Check that all the pulley set screws are on the flat spots of the shaft. I had that happen a few times. You pick that car up and give the wheels a spin and it all looks good, but under load from the engine it just spins free. Loosen them all and tighten them up again w/a little blue locktite.

Also check the dogbones or universals. If you are missing one, that could cause it to veer.

Because this problem is major and you need to rebuild the diff anyway, I think it's time to rebuild everything and inspect all parts.

I don't think there such a thing as maximum weight.

If anything - everyone else would be happy that you're over weight!

that is good to know becauase i thought that they were measuring max weight also. but you are right, it makes sense, max weight should not be an issue

no max weight rule. just min weight at 1725g.

To ensure you dont go below this weight it is best to weigh the car with rims but no foam or very very worn full wheels.

Default tire diameter

what is the result of running smaller diameter tires up front?

and vice versa?

The car won't handle quite right with larger fronts. Besides that, most people find the rears wear faster, so you normally start with smaller fronts.
