Well tonight is the first night Im going to be racing with these rubbers, I have been practicing with them and there not so bad. You really got to make sure you don't put too much or too little traction action on them though, last week at practice I put too much on the inner front (came out maybe more than 50, like 75%...I was getting lame turns and too much grip. It does wear off faster though so you got to be careful I noticed.
Well wish me luck.
