i was a rookie this year, so i really didn't know if it was the car or me,plus i probably lost my right rear tire 80% of the races i was in,due to one thing or another.when i did get to race the whole race, i noticed that i really seemed to have to baby the throttle off of the turns to keep from going sideways. i put in a 9" ford that a buddy had in his car. I noticed right away that it was crooked(wheel to wheel is 108" on right side and 105 3/4" on left.my buddy says he likes it that way,but i'm wondering if our driving styles are that much different, or if it's just me,or might that be a big part of the problem. i raced probably 16 of 22 weeks this year,and didn't win any.also it seems to get worse as the track gets slicker,i can half-assed run with the fast guys in the heats, but haven't had anything for them in the features.anyone?

What you are talking about is rearend lead and can be used to tighten or loosen a car depending on which way you go. However, the most lead I have ever heard a chassis maker recommend is 1/4". 2 1/4" is way out of the ball park. Not only would it throw your set up way off but you probably had to develop some bad driving habits in order to keep the car on the track. My advice is to square that rearend up - and don't listen to too much more advice from that "friend".

49 is right square that off.you must have looked like a dog that got beat running down the track the only angle you need is pinion angle suprising you didn't get yourself hurt running something like that it as for loosing tires do you mean you blow them or got them to hot if your blowing them have you tried to run tubes?what tire pressure do you run and what kinda wheels do you have. and just curious how did you make that so offset did you cut the control arms or what

the ol' boy that gave me the rear end had already welded the lower mounts on and i think the housing must have been moved before he did the left one. it bolted right up and the drive shaft is straight.he set the pinion angle when we welded the ears on the top of the housing.it's also sticking out a little further(2"?)on the left than it is on the right,the wheels,i mean.

oh yeah, the tire thing,if i didn't have someone cut my right rear tire, i'd roll it off the bead,one time i pancaked the wall,and that was just a stupid mistake i made,did a little more than flattened a tire that week.i started out with american racing D-hole steel rims,but now i have bart d-holes,i run about 17-18 lbs in that tire,and i run tubes,i also baby-powder the **** out of them.

your big problem might have been that the angle of the rear ennd made your tire stick out further in the front and made it ez target when ever you rubbed something do you run passerger tires or a pull off racing tire? stock pass tires need more air then you are running i never go under 20# on the right side i also run aero wheels they are the best for the money i found them on line for $29 for black mods and 32 for silver powder coat in 15X7/8

first square rearend, go from the center of the lower balljoint back to the housing on both sides. then if you have to shorting the top trailing arms to get between 7 to 9 degees of pinion angle.

(make sure your lower control arms aren't bent. Measure from the bottom of the ball joint were the grease zirt is that is the center. thats the easiest way I've found. Have the car on the floor while doing this 2people needed for accuracy. hope I can help)
