anyone have good luck with these yet? i have a set on my 8v and it rips. they are 39mm flat slides off a cbr 900. i havent dynoed it yet but i trapped 97mph in the 1/4 on a horribly hot and humid day. it pulls hard to 7500rpm. i just got it done so there is some tunning left but im very satisfied. the car is set up for road racing but if i run my slicks it definitely has a 13 in it. went a 14.35@97 with a horrible 60' of 2.4.
