well i bought these over a month ago and im quite impressed with them. they werent to hard to install (check the FAQ forum for the DIY) and there is a noticeable difference(not much but you can notice). i paid $155 canadian for the pair.
it cleared up quite alot of the clunking in the rear of the car (and my old RSM's were still in ok shape). there are two settiings Race and Street, i havent tried race yet but i assume the ride is a little stiffer in the back. I plan on changing to race when i get my shocks installed. i will update if i feel any positive or negative feedback.
my rating of this product is 9/10
my rating of the price is 8/10
