SPC upper control arms

[XLexusTech]

Anyone know if these arms allow for larger wheels for a stock sub?
My understanding is the Speed tech arms are narrowed for this.

However I thought maybe the SPC arms offer the same clearance.

I really like the no shims adjustability of the SPC arms.

I have a stock sub and stock lowers, SPC uppers with extra tall ball joints (SC&C stage 2 plus). Wheels are 17x8 with 5 1/8" BS. The clearance is pretty tight from the wheel to the upper control arm. No room for any more width without rubbing, at least on this setup. Maybe with 18" wheels and just the tall joints not the extra tall. This is a 71 Nova, maybe a little more room on a Camaro towards the fender, Im not sure.
