Folks

Looking on the web and in the wiki everything is about the largest rims that can be fitted to cars.

I want to know id I can fit 13" rims onto the R31 rear end.

I know that they came with 14" rims standard.

I have also heard rumors that if you grind off the cooling fins off the calipers and remove the dust cover plate, 13" rims fit ...just.

Its just that 14" jap rims seem hard to find, and 13" suit the 1k so much better.

Hav ya got a spare drum to butcher? and you can school the rest of us!

dude if no one can comferm ill lift the diff tomorro and get lurch to side a rim on my r31 diff in on the ground atm

I had 13s (alloys) on mine, with about half the height of the cooling fins removed. Depending on wheel offset and how much more you take off 13" steelies could be possible.

some 13 inch mags will fit, most will not

Oh and this is a disc rear end that came from a silloutte not the drum rear, which I believe came with 15" rims standard. It was the standard models that came with 14" rims.

If the rumor about grinding the cooling fins off refered to the drum setup, that would make sense. The cooling fins on the disk calipers are pretty small. i didint think that they would make difference.

And thanks Perthute if you can check, that would be great.

No luck from anyone?

Oh well, my minions have been working hard, and it seems that I may be able to provide you all with an answer shortly.

have you got the diff?
you can borrow my rims dude..

Yeah I have the diff, just that its in parts in the shed of horrors.

If I get the chance this break, ill put the diff together, on one side at least, and drop by to visit. Who knows perhaps ill have some in my greasy little mits soon anyways thanks to some awsome dude and some ebay action!

I ran 13's on mine for 12 months. As mentioned below i had to grind the cooling fins down a bit (DISC BRAKE REAR).
