I have fks aswell, and living on a farm in the middle of know where is a pain,the car bounces like crazy, and i cant do no more than 20 mph.BUT the roads around here have being resurfaced and there so smooth and the fks are fantastic, but any bump or un smoothness and there useless have gone around a corner, with a slight bump and the car bounced side ways . I am going to persist with them and see if i can get them to work better. G
p.s. having being drinking a lot of stella so if it dont make sense - appaolagies
