MR33 Bumper & Body Space Setup Sponge 18x13x5mm (3) MR33-BBSS

These MR33 bumper and body space setup sponges give you precise control over your RC car's handling characteristics. Each pack includes three high density foam pieces measuring 18x13x5mm, perfectly sized for fine tuning the gap between your bumper assembly and body shell on 1/10 scale touring cars and pan cars.

Proper spacing between your bumper and body affects everything from aerodynamics to weight distribution. Too much gap creates turbulence and reduces downforce. Too little space causes rubbing that wears through expensive paint jobs. These sponges let you dial in the exact spacing that matches your track conditions and driving style.

The closed cell foam construction maintains consistent thickness under compression, so your setup stays stable through long mains and practice sessions. Unlike cheaper alternatives that compress permanently after a few runs, these sponges bounce back to their original shape. That means your carefully tuned setup remains consistent from the first lap to the checkered flag.

Installation is straightforward. Position the sponges between your bumper mount and body posts, then secure your body clips as normal. The 18x13mm footprint provides excellent surface contact without interfering with body post placement or bumper movement. The 5mm thickness gives you a solid starting point that you can adjust by stacking or trimming based on your specific chassis and body combination.

Experienced racers know that championship winning setups come down to millimeters. These sponges give you the precision to find those critical millimeters. Whether you're chasing faster lap times on high bite carpet or looking for more stability on slick asphalt, proper bumper to body spacing is a tuning variable you can't ignore.

Each sponge weighs almost nothing, so you're adding adjustability without sacrificing your car's power to weight ratio. The neutral black color won't show through clear body shells, keeping your race car looking clean and professional. Three pieces per pack means you have spares ready when you need to make quick changes between heats or try different configurations during practice.
