I know that our cars need different front and rear offsets for their wheels. I know that Ronals are all the same offset, but use spacers in the front to make up for the difference. I am wondering if you can do the same with GTA rims? For example, if you had a set of four rear GTA wheels, could you run a pair up front with a spacer?

And, for the record, what is the difference in offset between front and rear?

Thanks a lot.

 

IIRC the offset difference is 16mm on the GTA wheels. and yes you can run rears on the front with spacers. I am counting on added track width from my new hub/brake combo to run 4 rears on the car so I dont need spacers for the GTA wheels or for the R15's.

 

Thanks for the reply.

I am guessing I'd also need longer lug nuts, like they have for the front of a set of Ronals?

Anyone know the part number of a lug that would work?

 

I can look on the invoice for my hubs for the ARP number for the lugs but if you want to look on your own the lugs are M12 x 1.5 thread pitch. Any of these except the toyota ones are close. I dont know the knurl diameter you would need Summit

 

IROC wheels are 16x8 on 4.75 bolt pattern and in front they have a backspace of 4.75 in. and in the rear they have 5.25 in. of backspacing
