A simple question really, but I'm looking at some 18" lightweight wheels for my 57 plate MCS. From what I have read the 17's that come on it are ET48, and the JCW 18s are ET52. Both are 7" wide though?

Now, having seen a few Works wheel equipped R56 MCSs knocking around I have always thought they looked a bit shallow and indented (just a personal opinion, no offence intended), so would I be able to get away with a 7.5 and a lower offset (say ET45/48), or is there a reason why the JCW wheels are the same width as the 17"s?

No doubt once I have the above sorted I shall have other questions re tyres.

all depends on your brake kit and the wheel itself - width of, and interior spoke design etc.

So there is no "perfect" ET for an R56.

The brakes are the standard OEM setup (for now), however as I only do the odd track day a year, the only upgrade I can ever see happening in that dep't is upgraded pads & discs.

The offset of 52 for the R53 is ridiculous. (I run 42 rear, 34 front). The R56 should have even more clearence for 8" wheels (8" is doable on the R53)

Thanks Damo, I have decided that the max I would want to go is 7.5" width, however the offset is still troubling me a bit. I'm thinking a max of ET40 might be doable, but feel that may be pushing it to the limit?!? I've also asked a couple of wheel dealers to quote me what they think will be the best fitment for the wheels I have chosen.

40 would be a bit of a squeeze at the rear (outside edge) on an R53 and have a bit of rubbing, but should be fine for an R56. I think it was the fireball guy that said there is loads of room for big wheels on the R56.

Hmmm, I think he may be right, this is what the rears on my car look like (17" flames on SS)...

Forgot to mention in my other post, I was talking about a lowered R53.

7.5" ET40 on a standard height R56 should be more than fine!

I think 7.5" somewhere on or between ET40-45 is what I'm going to go for. I just need to sort out what tyre dimensions to go for now! Any suggestions, 215/35/18?

Cheers

215/35 R18 OR 225/35 R18. Also depends a lot on the tyre. I have 215/35 R18's Yoko;s and they're very wide. Wider I'd say than some other makes of 225/35 R18's (toyo's defo!)
