since plaids are made of purple compound with a hard compound on the outside edge, they can make the car twitchy turning in and pushy through the middle of the corner....
you can do things to the chassis to counteract most of this, but that makes the car more inconsistent..... some people like a pushy car by nature, but if you want good consistant stearing, use double purples up front....
and just so you know, plaids were designed for outdoor asphalt use.....for mostly nitro sedans......not for carpet.....
