San Diego roads can get pretty bumpy in places. I used to run them firmer but got tired of it. On a smooth racetrack, the hardest setting feels like it should be harder!! I couldn't believe the transformation. Plus I like that I can corner balance them very easily once I decide how low to set them.
I've had them for 4 years, 60k and no sign of any wear.
Great to hear yours are holding up.
The last track had about a 1 foot dip in a 70 mph sweeper right hander that another NSX with after market suspension would almost lose and these would barely lose composure over the same thing.
With slicks, I now need a harness bar, I can't hold on!
