Okay, so i've 90% sorted my Z4m R - I'll reveal all when i take delivery of it... (Fingers crossed next week)

I'm going to order some alloys and tyres for it straight away, as i want to sell the current 224m alloys and conti-sport run flats around xmas time - People tend to have a bit of cash from presents etc...

The new wheels i want is where my question comes in...

What are the widest wheels i can fit without any issues? I plan on lowering the car so the alloys are fitted to the arches, and dont want any rubbing etc...

I'd love to run 255x18 fronts and 275x18 rears, wide as f**k i know, but i'd like the car to have a 'fatter stance'

Do you think i'd need to have the camber adjusted? Can this be done on stock parts, do i need camber plates?

Any help would be great, if anyones done anything bigger, similar, or the same, again please chip in... Thanks :evil: :evil: :evil: :evil:
 
Hi and welcome :thumbsup:
Check on this site threads and on the tinterweb for offset calculators. There are a number of sites that will compare standards with offsets.
 
Standard M tyres are not run-flats.

I am running a set of BBS CH's and the sizes are:
ET35 8.5jx19 (235/35/19 Tyres)
ET20 10jx19 (265/30/19 Tyres)

My car is not lowered and i reckon i could run 275's easily on the rear........ running 285's would require a bit of adjustment (maybe coilovers).

The Manhart v10 z4 runs 285's on the same size wheels i have but i don't no if there are any suspension mods..... i reckon 255's on the front would rub as there is not much space up front unless you run an aggresive set-up and coil overs (not much adjustment in the standard set-up).
