there are a few reasons!
1) i am a bit of a perfectionist, and this costs me a fortune!
2)the ride is far better on a coilover kit to standrad shocks and springs!
3handling is better
4)i can lower as far down as 85mm! so i can go down untill the arches rub then just adjust them up a bit to get the perfect ride hieght.
5) the car is an r-reg so the shocks were probably going to wear out sooner rather then later
6)if i can lower it the max then it will look better in my oppion, this is the main reason why the bodystyling is so subtle!
Any more questions my dear?
