i dunno, in most cases of coilovers that ive used you can solve bouncy bouncy by playing with the dampener adjustments, thats partially why they are there. I dunno, I'm going to go ride in jay's car and only 1.3's car to decide what I think... at 650 I can afford 2 of them for every pair of Tiens i could buy.. and that extra money can go towards hard tie rods, and TC rods, and possibly rear lower control arms (i MAY have bent one slightly drifting the gold coupe)
