Anti Roll / Sway Bar Kit, MX5 Mk3/3.5/3.75

SKU: NC0-0990

Together with I.L.Motorsport, we have produced this aluminum sway bar kit for all Mazda MX-5 Mk3 from 2005 and later. The kit is made in AL7050, includes new front and rear sway bar, new bushings and brackets, and is TÜV certified for the European market.

The photograph was taken during the TÜV testing for product stability. After 1,000,000 cycles on the testing machine, bar stiffness suffered no loss.
This is a 35% stiffer and 45% lighter sway bar set, and with TÜV testing and certification, it is legal for use throughout Europe.

The effect is to really flatten the ride. The car feels like it is on rails with minimal body roll even on hard cornering. We have this kit fitted to our own car and I have to say that the ride is now 'near perfect' :-))

Fits all Mk3, Mk3.5 & 3.75 models, 2005>2015

I was initially concerned that I was just kidding myself that the car felt so much better with these fitted, but no, they really are that good, as other reviewers have said. Response on initial turn-in is better and cornering stability is improved. Well worth the expense and fitting fairly straightforward, although I did have to fit new drop links as the old ones resolutely refused to come off in one piece due to seized threads.

definatly a recomended upgrade! has compleatly removed the twichy steering and steering wheel jerk caused by potholes that you get with the standard rolebars. i was very surprised by the difference these make. they have increased cruising speeds through sweeping bends by 10mph. also they have cut down the amount steering wander under hard acceleration. b4 fitting these my 5 could wander nearly 2 feet off line in either direction after fitting it stays on its line. seriously i cant not recomend these highly enough, whats more if you combine these with new shocks n springs and a good wheel alignment you make your mx5 ride and handle like a 100k supercar!

Handling is improved but wouldnt say it has transformed the car. I fitted these along with the eibach 30mm springs. The car is noticeably lower and takes sweeping corners flatter and with more confidence and a bit more enthusiasm than before. There remains some body roll especially if you transfer weight from one side of the car to another quickly however it’s a reasonable comprise on British roads as the comfort levels remain good; the same as before (Mk3.5 sport tech). If you want to transform the car for the track these won’t do it. Id try the eibach bars with the polyurethane bushes. I’m happy with the compromise as I’ve got to put up with the ride for 1.5 hours a day!

These must be the best bang for buck, easy to fit suspension upgrades available. The reduced roll is remarkable and the car generally feels more planted and go kart like through the twisties. Ride quality is unaffected with the standard suspension. The only problem I had during fitting was two of the front bracket mounting bolts sheared on removal, overcome by drilling out and welding on captive nuts.

Had these anti-roll bars fitted to my MX5 3.5 Sport Tech 2.0 litre two weeks ago by MX5 Parts in Portsmouth and completely transformed the handling. Constant bump steer and twitchy feel of the standard MX5 Sport is gone to be replaced by accurate steering with noticeably less body roll and far high entry and exit speeds. Interestingly, the ride has also IMPROVED. This sounds counter-intuitive but the stronger but much lighter aluminium bars seem to counter the Bilsteins and revised springs of the 3.5 Sport and give the almost perfect ride for a fast road / occasional track day car.

Just had these fitted to my mk3 sport by Blink motorsport. I'm impressed with them. stiffer than standard, matched front and rears and lighter than standard. I have noticed (as have the other reviewers) that cornering is much flatter and more stable making the car much more fun!I have H&R lowering springs which also help but I always thought the car was no stiff enough in the corners. Coilovers wasn't an option for me considering my budget so these fit the bill and very happy with it.

These are excellent ARBs that do make a considerable difference in flattening out roll on corners, however, it must be remembered that no one part of suspension mod must be carried out in isolation. My Mk3.5 is a Sport Black model, to all intents and purposes a Sport-tech model, this means it comes as standard with the Bilstein shock absorbers, I have also had the -30mm Eibach springs fitted. The car has done in the region of 8500 miles. What I have notced since fitting these ARBs is that the car is a bit more jittery on road surfaces with unevenness at high frequency, close washboarding if that makes sense to anyone, it just seems that the shocks are less able to react to this particular road surface, conversely, if you are on a road surface with deep wallowing humps and bumps, the car itself wallows a bit. Perhaps time for me to be reviewing the shocks themselves and get all these part working together rather than against. Overall though I am pleased with this product it has made a noticeable difference ton the car's cornering on ideal road surfaces.

Contrary to other reviewers, I didn't notice any significant change in the handling of my Mk3 which disappointed me. My car has never wallowed when cornering although there was a slight roll when cornering hard. I was expecting a 'flat' feel when cornering after fitting these sway bars, but alas largely the same as before. I wonder whether my ZSport with it's Bilstien suspension was firmer when cornering than other models and so lessened the impact of these sway bars?

This is an extraordinary product! The car ride is fattened and more km/h can be achieved in every turn! The ride comfort is not affected at all and you always think that the car can turn even faster...This product combined with MazdaSpeed shocks and eibach pro-kit springs (as I have) is the perfect combination for a road and track use car.Very happy customer:))

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

Items despatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be despatched the next working day.
