I've read many post about wheel adaptors, and the more I read, the more confused I get. I see people using adaptors from 1 inch to 2 .5 inch adaptors. What is the correct size adaptor to use with a 4th gen 16 X 8 Trans Am wheel going on a 87 Trans Am with a drum brake rear ? Should the front adaptors be different than the rear?

 

If I remember correctly I happilly used 1.25" in the rear

and 2.25" on the front.

Some people are using 2" all around.

Another option for the rear, is to get a 4th gen rear, and not use any spacers at all for the rear. Thats what I have done (did the spacers first, the swapped the rear) I got my 3.42 posi disc rear for $300. thats pretty close to the price of 4 spacers.

Hope I helped.

 

to get perfect thirdgen backspacing and offset (for 16" wheels) on fourthgen 16x8 wheels, you would need 2.15" spacers front, and 1.5" spacers rear. With a drum rear, you'd actually need more like a 1.65" spacer rear, since there is a thin spacer when using 16" wheels on a drum rear from the factory on thirdgens.

I'm running 2" all around, and i think it looks good that way.

I'd recommend the 2" all around or just swapping to a fourthgen rear setup since you do have drums in back.

 

I'm running 2" on all 4 corners.

 

I'm also running 2" adapters all the way around and no problems with them (knocking on wood)............I'm running aftermarket rims though....

 

Thanks for the quick replies. Any one have any 2" adapters they would like to sell for a modest price?

 

Heres a set
