[s-cars] Snow tires for the A4

[Eric Phillips]

Larry (et. al.)

The ECS Sys3 is 993TT calipers over Porsche 322 x 32 rotor rings.
They *barely* fit under 16" Avus.  And fit under some 16" Fuchs, and
not some others.  AIUI, ECS recommends 17" wheels for this combo.
This is very similar to the 993TT caliper/RS2 bracket/323X30 A8L D2
rotor combo that Gabe and I (and others) are running.

Which, BTW, fit in much the same way.  5mm spacers helped give me
piece of mind on my 16" Avus, but they weren't strictly needed.

BIRA Sys1 is Boxster monblocs over 314x25 Audi rotors.  Supposedly,
these fit comfortably under Fuchs, without spacers.  Dave Forgie has
this set up on his UrS4 with Fuchs, so he can provide fitment info.

I dunno if this helps any, but there it is.  :)
