KH Discs vs 73+ Discs
Re SBP, you can now buy new 17" alloy wheels in SBP, so you aren't limited in any way.
Not limited in any way?
Coys makes
1 off the shelf wheel (the C-5) for the 5x4" pattern. 1. It's available in quite a few sizes, but the backspacing is so limited you'll only be able to use a 7" wide rim up front and an 8" wide rim out back, although you'll have your choice of 17, 18, or 20" rims for those sizes. Still, the backspacing will limit your tire options on even those rims.
Show Wheels makes
2, one of which is a 5 spoke style very similar to the Coys wheel. They are available in 17x7 and 17x8 only, and the backspace again is going to limit tire width.
My point is, yes, there are 17, 18, and even 20" rims available for the SBP. But only if you like 1 of the 3 wheels available off the shelf, and only if you're getting those rims for looks, not maximizing your cornering ability. If you want something other than those 3, or something with the right backspace to run wider tires, you're looking at paying for custom rims, and it would be cheaper to convert the whole car to BBP and
then buy rims than do that.
