Lowering suspension - but don't want to rub wheel wells

I'm going to lower the suspension by cutting the coil springs and lowering the rear leaf springs. The only thing is that with the lowered suspension, how can I be sure that the wheels won't be rubbing on the wheel wells when, say, you go over a bump or something in the nature of causing the springs to compress?

I want to go as low as possible, but I also don't want to be having any tire on wheel well contact over bumps. How can I assure this?

Thanks

 

Measure from the top of the axle to the bump stops. This needs to be less than the top of the tire to the wheel well in the rear.

In the front, you can do the same, but turn the tires full lock each way when measuring since the fender lip usually ends up being inthe way.

 

If the tires rub, your tires are too big or your wheels are too wide.

 

I just went for it... only when the rear tires DID end up rubbing the top-inside of the fenderwells, did I choose to screw with it.

I basically cut the rear trunk bulkhead loose from the tops of the fenderwells on the inside of the trunk and with the rear seat removed... Cut the wheel wells all the way around (horizontal cut) just a bit higher than the wheel lip-- then added an inch and a half filler and welded it all back together again.

Cole's 54 (salinas boys) actually raised the wheel arches, and I have to assume the wheel tubs as well. Thats probably even cooler.

 

it aint low if it dont rub once in a while. just learn how to drive it.
