i went last sunday at the street nationals in my 182 and only managed a 15.03, i was gutted not to get into the 14's. i know what you mean about wheel spin it is slippery on that strip
Try not launching in the middle of the strip - if there is any moisture in the air, the middle of the strip gets greasy as every car parks in the same spot in the middle of the track and puts 2 lines of rubber in the same place - moisture and rubber makes a greasy track (ooh-err)
If you move to the far left or far right, you miss the rubber laid down and 'should' get better grip, though it differs day to day. Once you play around and find the best bit for grip you shouldn't have any issues, even with over 190 bhp I was only getting a chirp off the start line and that was on road tyres
thats it now grip been looking for drag slicks lately just so hard to find them over here. its done a 13.04 @ 107 but that was quite a lot different in setup to what it will be in a month or so
Hmmm, the issue with them is you put a huge amount of stress on the rest of the car, and you need to keep them warm - what are you using at the moment?
