is it ok to lower your car After you weld in SFCs? i think it should be, but would it change the "loading" of the car and cause problems because the SFCs were welded in with a different loading
thanks!

anyone know if it matters?

 

No. It doesn't make the slightest difference.

This whole thing about "loading" the SFCs is mistaken. The goal of the exercise has nothing to do with "loading"; what you're really trying to do, is to make sure that the car isn't tweaked some way or other from being held in some unnaturally bent position on jack stands paced at random points under the car. You want to make certain that the car is straight, or even slightly pre-stressed in the opposite direction of "load", so that when it's in its normal situation of sitting on 4 tires on the ground, it's straight. You only get one chance to weld them in: once they're in, they're there to stay.

FYI, I had my SFCs put on with a race car jig.... no wheels, no rear end, no engine, no interior, no nothing, just the shell on the jig, after pulling the body out to the factory's exact measured dimensions. Needless to say, the car is straight.

 

thanks for the reply. what do you mean pre stressed in the opp direction? how would i do that?

the one shot thing is what im nervous about. i want a perfectly straight car, like yours is.
