Chevelle Frame Rail Narrowing - Lateral-g Forums

HEEP · #1 01-01-2013, 12:06 PM

Ok, I have searched and read every thread on this subject. However, I could not see where anyone stated just how much was gained. What I am looking for is just how much you can gain from reducing the width of the frame rail itself. This is not narrowing the rails to create a four link drag race type setup. I am looking to add a larger tire in the rear. I'm set on a minimum of a 19" wheel, and my understanding is that I can get a 10" width under the well without any modification.
I have even thought of going full force and ordering these and grafting them in.

these are 3" tube that are supposed to fit under a stock body according to the company.

I am at the place where i need to make this decision so I can either move to the next step or stat cutting the frame.
Thanks in advance,
HEEP

Check out Scott Mocks 66 Chevelle build thread on here. Go to page 13, post 125. He narrowed his stock rear frame, and looks to have 315's back there. Actually he's got those tires on all 4 corners!
How wide do you want to go? I'm running 10" wheels out back, and I'm sure I could do an 11" with cut or rolled fenders, and the perfect back spacing.

You have a 68-72 car right? On my 67 i gained an inch and a half by reducing the width, but the earlier models frame is slightly different.

Due to the shape of the frame you will run into issues near the front.

this is a better solution.

Vince, I've looked into his kit. He is just now finalizing his build on the 70 models. He has the 66-67 taken care of. I just sent another email to him to see where he stands.
Might have to buy myself a late Christmas present.

I checked out Mr. Mocks Chevelle. That is the ABC kit installed. I'm ready to start cutting , I guess after I brace everything first.
