For new 93-95 90s, the S and CS models got 5-spoke "aero" Ronals,
6x15 with 195/65 HR 15 all-season rubber. Quattros got 6.5x15 10 (?)
spoke wheels with 205/60 15 rubber. Some dealers pooped and stuck
quattro buyers with the narrower combo.

Neither will fit. There isn't much clearance around the suspension
bits, front or rear. The widest you're going to be able to go is a
205 tire and a 7.5" rim.
Having said that, you *may* be able to squeeze a 215 under there if
you change the offset (significantly). Neither Tire Rack nor Discount
Tire Direct will "approve" anything wider than a 205...
Last spring, I put 7.5x16 TSW alloys with 205/55 16 D40 M2s on my
1993 90CS. They just fit, with less than 1/4" clearance around the
The other trouble you'll run into is that there are not too many wheels
available with the 4x108mm bolt pattern used on these cars. Most
TSW wheels will fit, moda and Borbet have a couple and that's about it.

I've been running the D40 M2s for about 6000 street miles and a
couple of track events and have been very pleased with the performance
for the price. The design is a little old and the wet performance is
not stunning, but still seems like a great 3-season tire.
They've stayed round and balanced. They didn't chunk or roll over
on the track, either.

The handbrake mechanism on the rear calipers is prone to seizing,
either with the brake on or off. It may just be the cables, but
brace yourself for calipers. I understand that once the mechanism
goes bad, they really can't be rebuilt...
