Evo brake / wheel upgrade
Discussion
Im upgrading to a set of ap 4 pots with 330mm discs on my e36 but speaking to ap they tell me im going to need 8J x 17 wheels and that my standard 7.5J x 17 fronts wont have enough offset and the caliper will rub on the inside of the spokes. Dont really want to swap the wheels as i want to keep the standard look of the car. The wheels ive got are the 5 spoke, I dont think putting a set of rears on the front is a good idea but it would keep the look standard.
Any suggestions?

Wheel spacers should do the trick surely?
Iwas thinking that, but its one of the things that AP said they wouldn't recomend.I've downloaded the template from the AP web and tried it on my fronts and they will rub a fair bit but they dont on the rears, i think ill try them on the front when i get a mo and see what the clearance is like.
Wheel spacers are a common modification and I have not heard of one problem caused because they have been fitted. I think that you will find this is A.P. being a little over cautious just to cover their arse in the event of anything going wrong, after all , it is no skin of their nose for you to fit correctly sized wheels and eradicate ANY possible problem whilst installing their product is it? ( Never mind the extra expense incurred or the fact that you may wish to keep your existing rims because you like them! ). Ring a few specialists ( Simpsons, Thorney ect. ) and get their opinion, but personally, I would go the aforementioned for sure. Good luck 
Wheel spacers can be a problem if they are poor quality or if they are very large.
Increasing the track by large amounts by using wheel spacers puts extra strain on the wheel bearings that they may not have been designed to take, this can lead to premature failure especially on a hard driven car.
If the spacers are of decent hub-centric type and the width is not huge then it shouldn't pose a problem. Even cars direct from the manufacturer have come with spacers, the 16v Integrale had 5mm spacers on the rear from the factory.
I also have a set of AP 4 pots waiting to go on my M3 Evo, I did consider getting another two 8.5J rear rims to go on the front but ended up buying a brand new set of 17x8J MV2 replicas. The advantage of these is they are lighter than BMW wheels by a few kilos.
