Here are my latest Indoor Carpet Setups, basically my winning setup of the Mibosport International event back in March with a pre production version of my LRP powered Mugen Seiki MTC2R!
Since the european carpet season starts soon, I'm going to start with it into October and can recommend it as a basic for both Stock and Modified.
Probably just some less steering angle or rear toe in for Stock necessary.
