Thank you. You have rated this product.
58mm Medium Bumpstop- Popular with our stock class autocross customers because you can't change springs but you can legally run these taller stops (which effectively raises spring rate legally and you can re-balance the car by using SOFT up front, and MEDIUM at the rear with that big Racing Beat front sway you got from us).
As used in our GWR bump stop kits but here sold individually so you can mix and match as you want. Can be used front or rear with all shock choices we offer. Note stock class limit is 60mm of bumpstop, so to max your length under the rules you could add 2mm hard spacer (or buy our 3 inch units and trim to exactly 60mm). And there are other creative ways to do it, you can chop off the smaller/softer first 8mm and use a 10mm spacer for 60mm total, etc.
