FW: E28 Wheels

["Hunt, Reed (CAP, GEFA)" <Reed.Hunt@xxxxxxxxxxxxx>]

Russ,

I stand corrected.  I was under the impression that the E28 M5 has rear
arches that are flared more than our non-M cars.  

I do believe that tires come into play here, though, and that was another
point I was trying to get across, though I didn't specifically mention it so
my fault.  

As you know, a 225 MM width means different things with different tires.  I
am pretty sure that even if my wheels had been 20MM offset (which I figure
is just under a third of an inch difference), they weren't going to fit with
my original tires without rolling (BFG TA Zs, by the way).  Perhaps the
Yokos are a "narrow" 225 - don't know for sure.  No plans to go with a 245,
at least not until I drop a turbo in it :-)

Regards,

Reed

	Correct.

	I would like to disagree here.  The E28 M5 wheels should fit any E28
without
	fender rolling or trimming.  This was the whole idea behind these
wheels.  On
	my E28 535iS, I have custom ground wheels with 18mm offset at 16x8.
These
	wheels fit exactly with Yoko A032R's @ 225/50's.  I couldn't ask for
a better
	fit without rolling or trimming.

	Now 13mm offset, thats tough.  I agree that thats a real tough
clearence. 
	It's also tough to get bigger than 245 width tires on these cars.
Dinan does
	it but uses a real large offset, ~25-30mm.  This is for the rear
clearence and
	then they use a spacer on the front wheels to clear the strut tower.

	 
	> Moral of this, don't go much, if at all below 20MM of offset!

	Again, 18mm is OK, but your mostly right, you can't go much more
that that.

	Take Care,
	Russ
