Radical Clubsport chassis number 100 is a red car that originally came with a RPE ZZR1100 engine with flat slide carbs, Willwood brakes and AVO dampers. In 2009 a front splitter / diffuser, rear wing and mounts, and lengthened rear diffuser were added. The car was raced with several different engines including a ZZR1100 ATMO, ZZR1200 turbo ATMO and a ZZR11 turbo. All of these were run with electronic fuel injection. At this time the brakes were upgraded to 280mm floating disks & HiSpec calipers all around. In 2014 the bodywork was replaced with Arc angles body parts and the engine was changed to a Hayabusa 1440cc. In October 2020 the engine was being rebuilt to 1340cc configuration.
