IL Motorsport Rear Chassis Brace, MX5 Mk1/2/2.5

SKU: 247

IL Motorsport Rear Chassis Brace Bar

This chassis brace was designed by a NASCAR chassis engineer for maximum rigidity. Each brace can be fitted in minutes and uses existing mounting holes. Even better, as you do not have to disturb any suspension mountings, there is no need to have wheel alignment carried out after fitting.

These braces are now made for us in Europe allowing us to both reduce the price and monitor quality control thereby bringing you a better product at a better price!

This rear bar can even be used in addition to the factory bar fitted to later cars for even greater strength.

Fits all Mk1, Mk2 & 2.5 models, 1989>2005

Fitted to my mk2.5 bolt holes line up 100% but with a standard exhaust it requires the ends of the tubes to be cut shorter at a angle to clear the exhaust. Not a big problem but fouls until cut.

Instalé esta barra en un NB2 con el escape de origen y, como ya se ha comentado aquí, los extremos chocan con el silenciador pues apenas si hay 1 cm de holgura y distancia entre ellos.La solución? en vez de mover la posición de la goma que sujeta el silencioso, como se ha dicho por aquí también, yo opté por lo seguro: rebajar -limar- la longitud de los extremos. Y lo hice al máximo, todo lo que pude hasta casi llegar a las soldaduras. Pero el corte lo hice con inclinación, en ángulo, rebajando más en la parte más cercana al silencioso, de manera que he ganado bastante distancia y ambos elementos no se tocan por mucho traqueteo que haya.Lógicamente, después de rebajar los puntales, tuve que pintar la pieza, cosa que no le vino mal pues el acabado de la misma es bastante justito (tanto en pintado como en soldaduras). Por todo lo demás me parece un elemento útil, que se ajusta perfectamente (casi parece un refuerzo más de origen), y que se instala en minutos incluso sin tener que levantar el coche. Una lástima que se fabrique con este defecto de tan fácil solución, pues acortando un poco los extremos y dándoles cierto ángulo en los cortes encajaría perfectamente a la primera.

Really light but feels super solid. Fitted in ten minutes. I removed the rear tie hooks I noticed when I fitted this brace and I'm pretty sure the car now weighs less ! Not had a chance to hit the twistys yet to check performance

Was dubious on the difference this would make, but for everyday use, this does smooth out the ride and removes quite a bit of shake from the rear of the car. The car is now noticeably quieter.I previously fitted a front chassis bar, and then completed the set after a few weeks. Front definitely makes the biggest difference, but rear is worthwhile if you don't have any bracing in place.Only surprise is that the nuts are 1/2 inch imperial! Had to dig out my old spanners to fit.

If you are considering buying this, just do it! I've just added front and read chassis braces to my '96 Mk1 1.6l which didn't have them factory fitted and it makes a big difference. Not just handling is improved even more, but the ride is much more comfortable over bumpy roads and those damn thick paint strips on the way into 30 mph limits! The car feels more predictable and stable when cornering at high speed but I'd say worth it for the ride improvement alone. Dead easy to fit, didn't even need to jack up for rear brace. Instructions from MX5parts are better than manufacturers but IL Motorsport's website has lots of photos from different angle so you can check where they go (referred to as "connection rod, back): http://www.ilmotorsport.com/shop/article_detail.php5?aid=172&oid=1123&depth=3&page=0&count=12&PHPSESSID=cf7600d1d91e2a7797d72697a2a1a078

I purchased one of these and it does improve the handling and ride on my Mk2.5 feeling far more secure and helps to reduce scuttle shake along with front top and bottom braces. However the one section of the rear brace fouled the MX5 parts back box fitted to car. Luckily I have a small engineering company in the village that I live, who allowed to use a bench grinder to grind a large 45% champher on the end of the tube to stop it fouling the back box. This could easily be resolved by the manufacturer doing it in the first place and this would stop the negative comments that appear on the site.I will say that MX5 parts always deliver in double quick time and I,m very pleased with everything I have bought from them and will continue to buy from them in the future.

Bought this on Sunday and received Tuesday due to bank holiday. Well made piece with spot on fixings for my mk2. Had a lot of sanding to do because I wanted to paint it annodised red with a candy cane pattern. Came out really well. Seems to have tightened the back end up quite abit around the corners. You seems to feel where your back end is a lot more if that makes sense. Thanks guys for the great product and summer offers, love the online store!

Ordered front and rear braces Thurs, arrived Fri and fitted Sat to my 1991 Mk1 - great service from MX 5 parts. These braces really do make a difference, make the suspension feel much more positive, cuts down 'skittiness' when cornering or riding over poor road surface. Can't understand why Mazda didn't think of these as standard items - if you have a Mk 1 with no braces, get some of these fitted!

Fits fine on a MK1 but needs to be upside down so the loop is at the top. Just bought a 2002 MK2.5 and it hits all of the exhaust pipes and back box. Solution is to cut the stubby open ends short with an angle grinder. 15 mins work job done and it now hangs as it should do with the loop at the bottom. Great piece of kit with the usual MX Parts super fast delivery but why do they make the studs so long when you can only get about 15 degree turn on a spanner?

My wife bought this together with the front brace for me for Christmas (aren't I a lucky chap?) These chassis braces have transformed the handling of my early Mk1! Previously it was a bit twitchy and skittish and it would rattle and slip over bumps and potholes. Now the chassis braces are fitted, it's a completely different car - it's planted, composed and solid. I can put down more power into bends now and it feels rigid and poised, just like my late Mk1. I'm delighted!Fitting the rear brace is a doddle and even the front brace was simple enough if you read the instructions carefully (I didn't, at the cost of a frustrated hour fitting the bolts the hard way). The bolt needs to be placed INSIDE the wishbone bracket, facing downwards, as opposed to how mine came assembled from the factory. It is then easily accessed with a spanner through the bottom gap between the lower wishbone and its bracket.It was unfortunate that the rather untidy welding, particularly on the front brace let down an otherwise excellent piece of kit, but I wouldn't let that stop you from getting a set!

Delivery Information - MX5 Parts

We understand that its really important for you to receive your goods in a timely fashion and for a competitive price. To ensure that we can deliver this we have developed a strategic partnership with both the Royal Mail and our courier partner, Think Worldwide.

At the present time, we only offer one delivery option ‘our carrier’. We will dispatch your goods with the most suitable carrier, for main land UK deliveries this is normally Royal Mail 1st class for packages weighing under 1.5kg and Think Worldwide for those that are over.

Our delivery charges are based on the weight of the consignment and the destination address. For UK mainland deliveries they start at £1.97 for a package weighing under 300g and rise to a MAXIMUM of £9.95 for a package weighing 1.5kg or over (EXCEPT very large bulky items that have an additional shipping surcharge added). The exact delivery cost will be clearly displayed at checkout.

Delivery times are estimated at 1-3 working days by Royal Mail, and 1-2 working days by Think Worldwide for mainland UK addresses. If you order before 3pm, Monday to Friday, we will dispatch the same day. If you order after 3pm, we will try to dispatch the same day, but if we cant it will be the next working day. Items ordered after 3pm Friday or over a weekend will be dispatched Monday. Items dispatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be dispatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t dispatch your order the next working day, we’ll email or phone you with a revised dispatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note, shipping times are an estimate, and can not be guaranteed. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

A signature is required for ALL orders delivered by Think Worldwide. Someone must be at your delivery address to sign for your parcel between 8am and 6pm on a working day. Please send it somewhere it can be reliably signed for, like your place of work, a neighbour, or perhaps your grans. We can (but we don’t like to) ask the courier to leave your parcel without a signature. If we do this, it will be YOUR responsibility if the parcel is lost or damaged. If you want it left, you need to give us your express instructions in the ‘additional information’ box at the end of the checkout process. It would be helpful if you could also indicate exactly where the package should be left.

If you need to change your delivery address, for any packages that have been dispatched with Think Worldwide, there will be an additional charge of £9.95 if the package has already been dispatched.

Please remember, even with Royal Mail deliveries, that any items which are too large to fit through your letter box will need someone to be available to receive the delivery.

Our Guarantee - MX5 Parts

We guarantee that you’ll be satisfied with mx5parts!

You have our absolute commitment as fellow MX-5 owners, car nuts, internet users and hard-working people that you’ll be satisfied with mx5parts. If you’re not, let us know and we’ll sort it out!

We guarantee “always fair prices”

MX5parts maintains an everyday savings pricing policy. We watch other retailers closely and maintain competitive pricing. The internet being the beast it is means that any Tom, Dick or Henrietta can set up a website in their back room and charge bargain basement/off the back of a lorry (guv) prices. Often they will have no stock, no returns policy, questionable security, no guarantees and of course poor customer service. MX5parts strives to be open and honest, so we will never inflate our prices to set up an artificial ‘sale’ (a common – and illegal – retail practice).

It is inevitable in an open market like the internet that there will be some individuals selling some items cheaper than we do, and some selling them for more than we do, just as in the high street. We take great pride in offering a fast, efficient, friendly and secure shopping experience, with great products at fair prices. We encourage our customers to shop around, but are very pleased to welcome them back again and again.

We guarantee to despatch your order when we say we will

If you order before 3pm, Monday to Friday and we have your items in stock , we’ll despatch the same day . If you order after 3pm, we’ll still try to despatch that day but, if we can’t, we’ll despatch the following day. Items ordered after 3pm Friday or over a weekend will be despatched Monday. Items despatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be despatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t despatch your order the next working day, we’ll email or phone you with a revised despatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

We guarantee to replace any goods which aren’t suitable

We guarantee to accept back any goods that you do not want, are not suitable, have changed your mind about, infact, for ANY reason, provided the goods reach us within 30 days of dispatch from us, in their original condition and packaging. Please tell us why you are returning the items, just for our records. The original purchase price of the goods will be refunded on to the card that was used for their purchase. Sorry, but we can not refund the carriage costs.

We guarantee full warranty support on all items

Just contact us if you have a warranty problem. All goods supplied by mx5parts are from official sources and are covered by the normal manufacturers warranty.

We guarantee that we will only charge your credit/switch card when your goods are dispatched

This is your right under UK law and, if we do anything else, it’s illegal!

(Please note: This doesn’t apply however if you have chosen to pay via PayPal. Due to the way PayPal works, you are effectively sending the money to us rather than us asking for it so in this instance we will have received payment at the time the order was placed and not when it is ready for dispatch).

We guarantee that we won’t pass your email details on to anyone else

Absolutely not. All your details are treated as strictly confidential. We’re internet users, too, and we know how annoying unsolicited email can be. We wouldn’t risk annoying you by being the cause of it.

We guarantee that shopping with us is safe
