On the face of it, seems like it should work with the off-set TA's, short spring and correct BS, with maybe only an extra 1/2" to the outside, and IMHO, it should be good for the bearings. I'm currently looking into doing 17x11's w/max BS in order to require the least necessary flares. ...but I have yet to determine what that max practical BS is.
Surely someone has already done this math a thousand times.
4.5 is the max backspace for a 15 inch wheel... And that will take some mods depending on your tire selection and remember these cars are +/- 500 thou or better anyway
I can't help you with the outside as I have flares...
15x10x4 with 295/50/15 Dunlop GTQ worked fine with stock trailing arms and a stock spring.
15x11x4 with 325/50/15 required relocating the ebrake cable to the top and a 1.5" shorter rear spring
15x12x4.5 with 325/50/15 required offset trailing arms and the same 1.5 shorter spring.
15x12x5 with 325/50/15would require some massaging of the frame to clear and an even shorter rear spring and double offset trailing arms.

Reason: 't
Backspacing on stock rims on an 80 is 4 5/8" , with offset trailing arms I installed Centerline Conve Pro's 15/10.5 front 15/12 rear with 5" backspacing. With a short spring.

...With flares i guess, have a pic to see how the wheels match them?

Wow, learn something new every day. I always thought it was 4 inch BS
I have a set of Ansen sloted mag wheels, 15x10 for the Corvette ...if you're interested I can send you a wheel to see how they fit...I have no clue what the shipping will be.

That would do for the front!! do you know where I could get 15x12's for the rear ?

I will pass for now.
I dont have offset trailing arms and nor do I have a shorter spring at the moment. And I would hate to mess up your wheels accidentally.
I have 15"X9" back wheels (draglite XP's) with 5.5" BS and 295 50's. with 5/16" spacers AND some trailing arm pocket mods AND offset trailing arms and a shortened spring, they tuck up under the car perfectly. So, with my car and those tires, wheel width and mods, 5 3/16" BS. Don't think 10" wheels would work with with my setup and the same bs.
15x9x5 1/2 BS with 1.25" adaptors fits a P295 50. I tried 15/10's first and sent them back because I didn't want the jacked up Nova look we all used to see in the high school parking lots.
until I get money to change them. The backs are 235-60x15 and the prev owner put 225-60x15 on the front... which was not a good idea with 10 inch rims..
Here's a few pictures of how they look on mine.
I've got my sights on a set of original aluminum wheels off a 78.

Let me get this right... You guys are saying that with a 2" off-set TA (double) and moving the brake line that you don't gain at least an extra 1.5 inch for additional BS??
BTW, you might get one on, but a 295 on an 8 - 8.5" rim results in sidewall instabilities...

As does a 275 under hard use...
I dont have time to measure right now but that is essentially correct with 15" wheels. With 17's or 18's you dont have the section width of the tire to deal with...
If you look at my pics you can see 12" of tread and a 12" rim with nearly 14" of section width
The frame gets close on the top much quicker and the sidewall bulge gets close on the bottom... and dont forget that the 15 inch tire with deflect a bit back towards the spring bolt under hard cornering
I have about 1/2 to 3/4 clearance every where... I need to be a bit more careful as I can adjust both the position of the trailing arm in the pocket and at the axle. I also have to be careful when adjusting camber...
I know Norvel modded his TA's & added some relief to his rear fame kickup to tuck those 18's
You MAY be able to squeeze 15x10x5's on with the mods your talking about with 295's/50/15 but it would be close.

YMMV
Good point about section width and deflection. The first car I ever tested with a data acquisition kept loosing a wheel speed sensor until we realized the tires were deflecting much further than had been anticipated, and was knocking them off under hard cornering.
Yes the sw gets you every time,,, on a G19 10x15 the tw is 10" and the SW is 13.2" so the tw will fit,,, but not the sw""
I've got a set of Aero lightweight,, steel wheels, non dot,,,, with a 4.5 or 4.75 back spacing??? dont remember,, 10x15 brand new, black, If anyone is interested will make a deal in them,,, great track wheels...
I got to get around to make a list of goodies for the for sale page... at least the ones that Howard has not spoken for yet
I have some black steel bassets that are similar 1 set of 15x11x4 (non dot) and 2 sets of 15x8x3 (non dot, DOT's are heavier and limited in sizes)
