1st gen Camaro with tubs, offsets?
 

Im about to buy wheels and need to know the offsets. Car will have tubs and aftermarket subframe. Car will also a big brake kit. wheel sizes will be
19x10
20x12

I have asked the same question in the past and the answer depends on what front frame and how wide the rear end is.
There are so many variables, I would call Frank at Prodigy and order the wheels from him. He will know exactly what you need after talking to you for 5 minutes. :cheers:

Ill be calling Frank soon for many parts. I got a deal on three piece wheels but have to get my order in by the end of the week. Man I know someone has done this combo.

Stock width rear end or narrowed? If you haven't done the rear end yet just order the b.s. you want and then mock them up and measure for the rear end width...it's truely the best way to do it!

For the front we need to know what aftermarket subrame....it does make a differance....

2nd this! its the best way cause you get the exact size lip you want. and yes the front subframe matters they are different track widths.
also another factor to remember what brakes you plan to use and if they chance the track width, how much/thick are the calipers..so the wheel pads are built thick enough to clear the face of your calipers.

Dude, my technical service is free for members. No purchase required. I don't care where you buying your wheels. Lots of people call me for their backspacing and then buy wheels somewhere else that we do not sell. I will help you with the backspacing. But I need more info.

Just call me

Thanks guys. Ill give you a call tomorrow.
Ill be doing the G bar 12bolt with the speedtech front end, pretty sure anyway:lol: I just figured I would get the backspace for that setup and build around those parts. :unibrow:

camaro2nv,
You should give Frank a call.... He is a really nice and easy going guy.

If it matters, I have a G-Bar, stock width rear end, mini-tubbed with 17x12s with 8.25 inch backspacing and that is pretty spot on.
