I have done 7,000 mile on H&R's and the car still feels fantastic. Forget the looks the car rides and feels BETTER on the H&R springs, the looks are a bonus.
It was truly awesome round the ring. I hit 160mph in Germany and the car felt very planted and superb. I spent an hour between 110 and 150 mph, no issues at all, awesome set up. I can confidently load up the suspension at 120+mph which is normally a challenge for a road car....
