Well I have a set of square CSL reps that are 8J x 18 with a 35ET that are in reasonable condition, and have non-runflat Kaiser Kenda 225/40 x 18 tyres fitted. (No, I'd never heard of them either)! Two of them are barely legal and the other two have maybe 3mm of tread, but I don't want much for them!
I was going to fit them to my Coupe just to see how different it felt on non-RFTs, but didn't really plan to keep them so I they could be available.
With the different offset they'll sit a bit further out in the wheel-arches than standard E86 wheels too.
But best of all I'm just down the road from you in Sandhurst! :lol:
So PM me if you might be interested, or would like to have a look at them.
I've only got a photo of one, but it gives you an idea.
