What are they?
Our custom moulded 36mm bump stops are the ideal choice and a great tool for fine tuning your suspension. Our 36mm bump stops are a specially designed multiple-use, progressive spring rate bump stop geared towards cars that have been lowered looking to recover lost shock travel. A collaboration between Fat Cat Motorsports and 5X Racing, these special bump stops were originally designed by FCM then brought to life by us. They are built to utilize only the lower portion of the taller 76mm Speedthane bump stops, capturing the "sweet spot" of that much longer progressive rate stop. Since the 76mm stop is too long for most suspensions, (especially lowered suspensions) this 36mm stop allows the same style of bump stop - just without the length - and is perfectly sized for your lowered, reduced shock travel setup.
When you lower the suspension in your car, you lose shock travel due to the springs being shorter. This does not work well for stock length bump stops, as your shock will now have less distance between its body and the bump stop, causing a reduction in shock travel as the shock will bottom out on the bump stop even sooner than before lowering it. The easy solution to recover this lost shock travel is to use a shorter bump stop, and this is where our 36mm bump stops come in! Pushing that benefit even further, we offer three different densities to custom tune your ride characteristics. In the past, only one density of 36mm bump stop was offered - the stiffest density - so the name "Track Kit" was appropriate for racing and track use as the bump stop engagement was stiffer than most street users would prefer. Using our 36mm bump stops, a driver can lower their suspension without sacrificing shock travel and customize their ride characteristics by using one of our pre-made kits consisting of combinations of our: 100 in/lb Yellow (soft) 36mm bump stops, 200 in/lb Blue (medium) 36mm bump stops, and 300 in/lb Black (hard) 36mm bump stops. Of course one can always create their own kit by purchasing our bump stops individually HERE.
We realize bump stops are an education all in their own among the vast landscape of suspension technologies, so we strive to help educate you to the best of our knowledge with the help of Fat Cat Motorsports. There is a vast knowledgebase both on our website within our 5X Racing Technology and Information Center and online via forums and articles.
