I'm going to be putting my 02 together form a wreck and won't have money for rims and tires for a while.
So I was thinking of getting another pair of the wider rear rims and putting them on the front for a bit better grab, till I can get something better.
Anyone try this or see a problem with it??
Used oem rims seem to go cheap.
Thanks, Butch

 

Rear hub bore is 64mm, front is 70mm, they won't fit.

Ok, Thanks.
So I wonder how hard it would be to cut out the hub bore to make it fit?
And if they were cast the same, just one's bored out larger.
I know a couple guys that have machine shops, so that wouldn't be a problem. Thanks, Butch

 

It looks like the oem rims are the same on the outside, so the rears must be inset more. I wonder if I bored out a rear for the front, would the inset be too much?
Does anyone know the inset of these rims??
Thanks, Butch

 

You would be taking structural integrity away from the wheel when you machine it larger. They would fit and work but I would not recommend it. OE wheels are made to have just the load capacity of the vehicle they are going on. No more and no less. If you machine the wheel you will lower that amount.

 

I've seen/had it done with a few sets now that have extensive track mileage with no issues whatsoever. It is really a minimal amount of material that needs be machined. It will basically get rid of the "roll" on the inside edge of the bore. Go for it Butch!

 

First off, IF the REAR bore is 64mm and the front bore is 70mm, why would you have to machine a pair of rears to go on the front? If the REAR bore is LARGER than the front bore you would need hub rings for the fronts.

But I think this is a bad idea regardless. I believe (and feel free to correct me if I'm wrong) that a wider rim, and the necessarily wider section tire, would make the car more prone to oversteer as front grip increased and rear grip remained the same. This on a car that already oversteers seems like a bad idea.

 

You might want to check your logic there Tof

Butch, the last time I thought about doing this I came to the conclusion that I'd need to run a spacer on the fronts. This spacer will kill two birds with one stone since it will push the wheels outwards past the larger centerbore. I've seen pics of guys running 16x8 +50's from an FD RX7, so running rear wheels all around isn't that wacky.

I might mount them this weekend and take some pics just for fun. It'll be 245/45 RA1's on the back with 225/50 crap tires, both on rear wheels.
