I've seen some kid cut grooves into the ABS tire with a hacksaw blade, kid should become a tattoo artist, looked really good. He also filled two grooves he cut with hot glue and it gave the tire some bite.

To my surprise ABS has a decent following especially with low powered motors, went to a comp where a team used it exclusively. It was a tight and very technical track, man those guys could slide, it was like 4 cars were being driven on the same remote, those guys were in sync. These guys bling their cars out with CF, alloy parts and LED's a super paint jobs and they don't plan on rubbing fenders!
