New Wheels

Anyone have any luck on if 21x12 will fit the rear of a 63? I was browsing through the forums and found that someone was able to get 11.5s to fit. Not sure if that extra .5 is going to cause issues, or If I will need a spacer. Then again, thinking about if it will hit the outside of the wheel well area..... Let me know your thoughs.

I am curious what tires you plan to run on that.
Is the intention just for looks?

Purchased a W.4 Weistec turbo system, so looking to be able to run 325s on 21" in the rear. Having a very hard time finding 11.5 wide wheels, so wondering if 12 would fit.

The thing is that you should be looking for higher performance tires over wider tires.If you are worried about putting the power down 305 wide drag radials would do a lot more for your take-off than 325 would, even in Michelin PS4.
I would honestly start considering going to smaller wheels over wider wheels. If 18" fit over our brembos, that would definitely be my rear wheel size, but they do not.12" wide wheels only get heavier so evaluate what is important to your goals, not just wider wheels

Makes sense. Appreciate the input.
