competitive? Chet whittels 240z i now own was the its record holder at road atl till he droke this past summer in his e36. he lowered the record by 1 second but did not run under that at this years arrc. Oh yeah he won the arrc twice in that car. It is running an e88 head to boot. As far as brakes, went testing a barbers motorsports track down the road and I must say the brakes were perfect turning 1.43's on a green track. If you do your homework on the brakes the are not much of an issue. btw That 240z is probably the legal front running IT car I have seen.
