I ran these for four years on my k powered civic, covering thousands of miles, they never missed a beat, this was through vigorous use on track and on normal bumpy English roads! I personally cannot recommend these enough.
Performance on Road?
perfect, smooth yet hard and stable when your having some spirited driving.
Performance on Track?
on track, these were awesome, far superior to other suspension I have used in the past. easy for anyone to adjust the settings to the conditions/surface as appropriate.
Value for Money?
awesome, the only way you could beet them is to get them for free!
Would you buy again?
definitely, and I did!
