So how much (if any) rubber buildup is acceptable on the bottom of a touring car chassis running indoors on carpet?
Background --- I have been running 17.5 Sedan, USGT and VTA classes indoors on New mid/high grip carpet this winter and have been experiencing varying levels of rubber buildup on the outer edges of the chassis bottom. Even though it does not seem to hurt the performance I often clean this rubber buildup off of the chassis between rounds. Is this extra step necessary? Is rubber buildup something to worry about?
Obviously the chassis edges are rubbing on the track surface and removing rubber from it. Is this slowing the corner speed of my cars down noticeably or is the affect nothing to worry about?
What is everyone's opinion that has run on high grip carpet? Thanks!
