Speedy,Haven't measured tires but have to run same size on all 4 wheels.I run 40psi RF,30LF and 40 in both rears.What about a larger front sway bar and stiffer springs in rear.I've got a 1/4 inch toe out in FT and rear.Thanks For the Reply,Mike

does same size mean in number only - say 205/60 13 etc. i would try several different brands of the same tire size cause we have found that we can get about 1.5 to 2" stagger using the same size but different brands. we even go so far as taking the smallest brand and have it shaved to about 1/4" tread depth to gain stagger. if not then i would focus on setting the car up with somewhere around 47% cross to get the car loose on entry. we had to do the same thing with a dodge neon we ran a couple of years back.i havent seen as high a pressure as that eithor. i typically run more than everyone else and i dont even come close to that. i would adjust down equally until you feel the tire are rolling over and then go up a bit. mine ran its best at 20 lf, 24 rf,20 lr, 20 rr.i would use the rear tire pressures to adjust the car since they only follow anyway. put it on scale and try adjusting up and down on them and see where it goes.

GMMan,

We have run 40 in the RF tire on asphalt track, it helps keep the tire from rolling under and chunking the tread off. But....for dirt, that is too much. Speedyd1's pressures are much more realistic. I've run left side tires as low as 12 pounds, but don't go under about 18 or 20 in right sides. If the track is very rough and wants to pop tires off the beads run tubes in 'em.

Think of it like in the snow. Run sicker tires on the back to alow the rear to swing around. Just the opposite of a rear wheel drive. You also need lower pressures as recommended buy other guys. But ke is to use throttle more so to pull you around. Find front wheel drive tires heat up faster. This of coarse means tire pressure rises faster too. Good luck

I have a 1989 cavalier and i here that running a fwd car on dirt will put you in the wall. the car is on the way and is still being built but i'm starting to have second thoughts. Is this true?

I ran a 92 cavalier last year (1st in points)

You can easily get 2"+- stagger by switching different brands of tires.

We have a 1/4 mile with steep banks. I ran low gear (Auto), and foot on the floor steering with the throttle.

I found a rear swaybar that got the rear loose, and helped over overcome the push.

The only time I got too close to the wall was when they overwatered the track.

I also got intimate with the infield signs (see link)

If at all possible lock (weld) the differential. Then your stagger will do some good. Clyde
