The RACE OPT RP-RT-103M Medium Rear Foam Tyre Set delivers focused rear traction for 1/10 scale Formula 1 cars. With a medium 25-degree hardness, these foams are intended for circuits that reward mechanical grip. They help you hold corner speed and deliver steadier exit traction lap after lap.
This medium compound gives a controlled feel and resists rapid breakdown on sticky surfaces. The 25-degree rating offers a compromise that works well for drivers who want competitive grip without constantly swapping tyres. Fitment is straightforward for typical F1 rear hubs like the F103 style.
