Default Weld rts 15x12 325/50-15 mt drag radial

Should that work with a 6.5 bs on a 2" per side narrowed rear in a 200 camaro? I don't mind bfh and rolling fenders.

Has anyone here run this? Pictures?

Your really going to have to Mini tub or cut to get them to fit. With 12'' wide, your 2'' narrow rear and 6.5'' backspacing means you wheels will already tuck and those tires are huge!

I wouldn't be surprised if you need to go to offset lower lca's and a mini tub. But I would love to hear from someone who has done it.

^^^^^ me too.
I'm thinking if a 2" narrowed uses a 5.5 bs on a 10" then a 6.5 on a 12 should put the lip on the outside in the same place. Just not sure about the inside. What offset would you think will work...keep in mind I do not want them to stick out.

Now I am no rim expert by all means but have been learning alot since I've decided to run a narrowed rear end and had to order custom wheels. <---------- (My disclamer lol)

The backspacing will mostly change the position of the wheel and how far it sticks out before the width. Backspacing and width go hand in hand because you can't run huge amounts of backspacing on a narrow wheel because it will put alot of stress on the wheel, wheel bearings & suspension parts, Most of the time when you have a wider wheel it's been widen behind the face of the wheel not infront of it. No matter the width of the wheel if the backspacing is not correct it will stick outside the fender no matter the type of car.

If you want a wheel that won't stick out you should stick to the correct backspacing for the length narrowed or add more backspacing. In your case 6.5'' backspacing with a narrowed rear end will cause the wheel to sit closer to the inside of the car which is what your looking for. The problem is the more you want the rim to tuck and wider you make it the more of the inside clearance you need.

If your willing to modify your wheel wells you could run the 12'' with 325's & 6.5''. If it was my car I would just do it with a 5.5 or 6'' bs to try and avoid offset lca's and mini tub. If you can run a 10'' wheel with those tires I would do a 6.5'' bs and clearance where needed. The 5.5'' backspacing on a 2'' narrowed rear end will put the wheel in the same spot as if it had stock wheels on it and all you would have to worry about if the tire will stick out not the rim.

I really hope that helps and makes some kind of sense lol.

How about calling the wheel manufacture for the details? They should be able to tell you the offset. I would really like to know too, as hopefully in a not to distant future, lol, I hope to get some 18x12's for my car.

Normal fit is a 15x10 with a 7.5 back space. It should be a case of simple math here. Since you are narrowing 2 inches, but going 2 inches wider than a 10 wide, then you should need the same back space of 7.5 inches. Tire size would be most critical to you. Hope this helps.

Well what do y'all think about race master mh dr's thinking maybe 325-17's instead that way I will have room for brake upgrades later. 17x11's if I can't tuck a 12 with a bfh and some heat. With rolled fenders
