What does the bumpstop do? It's what cushions your car on the big bumps when you get to the end of your suspension travel. It's basically the last part of your suspension travel. MX5's - especially NA and NB - spend a lot of time on their bumpstops, so they're a pretty important part of the suspension.
Strongly recommended for all 1990-97 MX5 - the stock bump stops are terrible. The stock bumpstops on NB and NC are similar to these, but suffer degradation with time and can actually crumble to dust. Swapping in a set of these stops on the rear of an early ND will give improved travel and decrease the chance of snap oversteer. Mazda moved to a stock bumpstop that is closer in design to this one on the RF and on 2018+ soft tops.
54mm in length. We think it's a good length for a MX5 at a typical lowered ride height. A shorter, stiffer bump stop will allow more travel before you start to hit the stop, but it also means a more abrupt transition on to the stop and that translates into decreased ride quality and less consistent handling.
Sold in pairs. Two pairs are needed per car.
Can be installed on all MX5's NA NB NC ND 1989-2020
