After a year of ownership I think it is time to write a reveiw.

Before this kit my 1,6 NA was riding on a rather stiff setup with standard shocks (+225.000 km) and H&R lowering springs. The ride was low and harsh on some occations. I did however never have any issues with front tyres rubbing the wheel arches or any inner parts.

I then changed over to the Koni Sport suspension, complete with new bushings all over. The height was set with the lower spring perches in the highest position in both ends. Unfortunately the result was not satisfying. Well the ride was brilliant, a significant improvement! But... the rear end was sitting sustantially higher than the front end, which in return was (too) low. When driving, slightly spirited, the front wheels would hit the inner liner. On two occations when I turned and passed a pavement (slight change of level) my front wheel made contact with the front wing and caused a lot of damage to it.

After this I decided to go back to original springs. I fitted these with the spring perches at the bottom level all around. Well at least the noise dissapeared, but the rear end were sitting very high compared to the front end (and compared to similar MX-5 on stock suspension). The ride was pretty good, but a little soft. I then fitted two Racing Beat sway bars to see how that change the behavior of the suspension. A fantastic improvement - and a must have (no matter which brand of sway bar you choose!).

Now in the continious search for the perfect setup, I decided to fit the Koni springs again. But this time with the front end in the top perch and the rear end in the middle perch. The looks have changed for the better now, even though the rear end still is higher than the front end. Oh yes, and I bended the edge of my front wing again...

So what annoys me - that the ride height at the forward end is just TOO low for my everyday use. Things would be perfect for me if it was possible to raise the front end maybe 15 - 20 mm. I have a suspicion that the forward springs sag just too much?
By the way - the springs are fitted correct all the way around.

My initial thoughts were that I could save a bit of money on the Sport Kit instead of a complete coil over. It was definitely a wrong decision, because I have spent a lot of money on changing springs and suspension alignment afterwards each time plus the repair on my front wing. At the moment I am looking for either a set of springs which does not lower the car so much(the shocks are perfect for me!) or a complete coil-over setup.

The quality of the kit, well I can't complain about it. It's decent quality, even though the yellow paint on the shocks is very thin and corrosion will probably show after a short time in the Scandinavian climate.

The shocks are perfect for my use, the ability to adjust the firmness is perfect for the combination of daily driving and trackday use. For me the spring rate is just a bit to low and the issue with the riding height is just annoying me too much to recommend them to anyone. If you don't mind the difference in height and want your car sitting low - well then the kit is perfect!

The quality of the product is four to five stars for me, but due to the above mentioned issues my experience with it is two stars. That's the reason why I am forced to give this product an average three star reveiw. Rating: 3 of 5 Stars! [3 of 5 Stars!]
