Offset on R32 Rims?

Does anybody here know the offset on the stock R32 16x8 inch wheels?

Also, on a related note, does anybody know if putting on a wider wheel, like a 9", would throw off either the ATTEZA or HICAS systems? I'm not terribly familiar with how they work, so I thought it best to ask.

The offset on an R32 GTR 16x8 stock wheels is 30 millimeters.

The offset on an R32 GTR 16x8 stock wheels is 30 millimeters. In addition to that, going to a 9 inch wheel will not affect attesa(4wd) or super hicas(4ws), it could however cause front tires to rub on your front fenders depending on which tire size you choose and how much distance you have between your tire and the fender. I had 17x9 wheels and 255 40 zr 17 tires on my GTR and on very hard cornering with bumps, experienced front tire rub on the front fenders. If you have adjustable spring tension on your suspension, you can go up enough on the spring to prevent rubbing in these situations. With the correct 30mm offset and fully adjustable suspension, going up an inch width on your wheels should not pose much of a problem.

If you're going for 17x9 or 18x9.5 wheels, go with +22 offset. I had the stock R33 GT-R wheels on my R32, +30 offset, and it had trouble with 245/17 tires (lowered car). Now I have 18x9.5, +22 with 265/18/35 and there is no rubbing.
