How wide a rear tire can you run with the C4 rear suspension and stock '69 bodywork?
Presently I'm running some C5Z wheels (10.5" width) with 285/18 tires on the rear. I could have fit some 295/18 tires there, but the incremental price difference was too damn high for just 10 mm of additional tread.
I have some 315/16 tires on my C4 that I've been meaning to try on the 69 when I get a free moment from other more "important" projects.
Wow, I'm surprised. That's quite wide considering. Did you notch the frame at all the gain that tire width, or does the C4 knuckle and links give you more room?
I didn't notch the frame as the inner wheelwell bodywork is basically on the same vertical plane as the frame rail, and I would have had to also cut and modify the bodywork. My intention at the start of the suspension conversion was to leave the bodywork unmodified.
The two trailing links are set inward substantially compared to the original C3 trailing arm, allowing the wheel/tire to pretty much set inward pretty close to the frame rail and inner bodywork.
