Since 2005 the Fat Cat Motorsports name has grown very popular among Mx5 racers and autocrosses. Focusing on highly specialized suspension builds, FCM is becoming a leader in the industry and fast drivers are turning to them for results. Launched by an engineer who found the Mx5 to be a perfect platform for autocross, today FCM supplies a complete line of suspension products from custom re-valved shocks in their coil over kits to re-engineered bump stops. Customers range from national champions to folks simply wanting a better ride, and FCM products have been featured on projects in Grassroots Motorsports magazine and Edmunds' Inside Line blog.

In our Mx5s, the bump stops were designed by Mazda to be an integral and functional part of the suspension. A common modification to the OEM bump stops has been to simply cut them, which cuts down their reliability and life span.
