hi sorry if this has been asked befor i tried the search but everything but came up.
i have been looking for some CSL wheels will 19" with 40 profile rubber fit straight on or is there any things to change ? its for a 2.5 z4 roadster on a 06 plate or will it be better going for 18"
cheers

19" and 40 profile is too big, you'll need 225/35 19 and 255/30 19 tyres - not cheap

TBH 18s would be good too.
