Looks really nice out of the box, shame you won't see it much but you'll tell the difference immediately
Just what my car needed fast shipping and easy install after getting the old ones out can’t wait to order a tuner next
Amazing product, car glides over bumps while staying rigid in corners.
Very comfortable and exceptionally weight 10 out of 10.
