wheels and backspacing
im trying to find a new set of wheels for my 1979 c3 but im having trouble finding wheels that will fit or more so the right size with backspacing im looking for a wider wheel then standard. I read another forum where a guy used 17x8 with 4" of backspacing in the front and 17x9.5 with 5" of backspacing in the rear im wondering if there is a size I can put both on the rear and front so the tires may be rotated that also have the clearance with the backspacing.
these are the wheels I would like but I don't think the sizes will work

The US Mags website shows that the wheel you referenced, is available in a 15x8, (and 15x9, for that matter) but they don't give a backspacing or centerbore dimension. Their page refers you to a "tech page", but it comes up blank.
The wheel would look really good on a C-3, as long as the fitment is correct. They do list a contact phone number, so I'd give them a call and get the details.
(BTW, caliper clearance in the backside of the wheel's spokes, is also a critical C-3 consideration)

9.5" on the front won't work unless you are flared.
You can order these in any backspace you want.

Or see if Coys has 17" in stock for Corvette fitment. Do not let people tell you a 4.5" backspace will work.

I have '89 vette rims on my '72 which has later more flared fenders on it....like on a '78+ shark.... I used 2.5" VBP wheel adapters to keep the same wheel center line.....moved the ebrake cable tab to behind the rotor, many guys go on top of the arm.....I also drilled/tapped the lower A arms where the spindles act to limit the tires off the sway bar or frame....made no difference in parking lots....or U turns.....
275/50/17 rear 255/50/17 front....
275/50/17 rear 255/50/17 front....

im glad those will fit but I really want a set like butnik x gasser wheels or more so with more spokes to me torque style wheels look better on a chevelle or Camaro. corvettes need more spokes like the c5 zo6 wheels or something
