Switching over to a bias ply front tire for the track and/or a set of skinnies can help as well. A radial tire especially a large, wide diameter tire/rim combo like a 245/45/17's or wider on an 8"-9" rim will experience hardly any side to side motion like a soft sidewall, bias ply drag tire. As a result, the back end moves around all over the place and the front end stays planted, this will cause the act of keeping the car going strait down the track, to be a bit of a chore.
If the bias ply isn't an option, going with a skinnier tire/rim package would help some, since a narrower tire is less prone to darting from side to side, like a wide tire is. You could always let a few pounds of air out of your current front tires to soften the side walls up a little, but that’s kind of counter productive to achieving your best time, since softer front tires increases their rolling resistance.

Do you have newer control arms ?? If you have worn bushings or stock arms they will sway alot, I know mine did, It was all over the place, Kinda make it more exciting.....I replaced the lower arms first and it made a big diference, Plus you have to play with air pressure and tires also..

I put 26x10.50x15 MT ET Streets on my GT. At 16-18 psi, it felt like a dog wagging its tail. It scared the crap out of me. At 20 psi, it feels quite normal and stable. I don't have enough torque or power to spin the tires loose even on a halfway decent track prep.

mismatched bias and radial will make the car a bit of a chore to keep strait. I would invest in some skinnies for the front as well.

Guessing your supercharged running the 1/8th. Guy i know has an 03 cobra and used to run it with et streets in the back no skinnies and he said the sway was really bad. He got skinnies in the front and he said there is almost no sway. He traps 133 in the 1/4
weld prostars, draglights, whatever you like the looks of. 15x3.5 or if you want to go a little wider 15x5. I went 15x5 becuase i have a daily driver and run skinnies up front all the timewht99gtconv said:

I've heard that too. The reason I was given is that radials (front) and bias ply (rear) tires will track differently. Having the same type on both axles will make them track the same. I don't have personal experience on that so I didn't want to post it. We already have too much of that.Ruckus46Gt said:

Others know what they are talking about...worth a try.
