1969 Camaro HRE fitment

[Dr.Acula]

What would be the ideal back spacing for an 18x8.5 rim on the front of a 69 Camaro with disc brakes?

Thanks

Factory disc or aftermarket? If aftermarket, which ones?

Fronts have Willwood 6 pistons and the rears are Willwood 4's. I was told that 18x8.5 should have a back space of 5.0"? I'm not sure if thats correct or not?


Thanks!

I've also been told that 18x8.5 fronts will require 5.25", 5.35", or 5.5" not exactly sure which to go with but I've contacted CCW, HRE, and have done tons of research and can't get any straight forward answers. I plan on using a 255/40/18 on the front as well as a 285/40/18 in the rear.

Your not going to get a straight answer... it's an old car with aftermarket parts.

If you are purchasing custom wheels, recommend you have all four wheel openings measured.

I'm just trying to get a idea of what I might need so I can work off that. Thanks anyways!

Wilwood 6-piston like the Forged Narrow Superlite 6R? If so, then the track width change for the 140-9804 brake kits is +.38" per side relative to the OE track width. Ride height is the next thing to consider along with tire size/diameter since the two will both play a part in fitment, so measuring your fitment or mocking things up really would be your best bet.

My guess is that 5" BS won't be enough given your brakes and assuming a 245/255 tire with 25"+ diameter. You can always space a wheel outward to compensate for too much BS...going the other way is a bit tougher.

Yes, the Superlite 6R's are what I have up front. So you're saying 5" is too much backspacing? I thought I would need more backspace up front
