S-Car Crew,

Greetings!  I trust every had a grand all hallows eve!

I'm the progenitor of BIRA's Sys3.  One of the reasons I was able to
convince Greg Amy into doing Sys3 was the fact that Audi's 314x30 EuroA8
lies about 10mm closer the strut than the 312x25 US A8 rotor that we
used in Sys1. Thus, not only does Sys3  provides a slightly larger
monobloc caliper (996 v. Boxster) and a rotor thats 2x5mm larger, but
its "inboard plane" lets more wheels fit.  I ran S6 Avus wheels over
Sys3 on my '91 200TQA and there are pictures of this combo on our
website under "Member's Rides."  There's also a "wheels we've
test-fitted" section under "information" that  includes member feed back
as to what wheels work and what do not.   We currently have over 300
members, and in the past,  many of them have helped their fellow members
or potential members by testing fitting a wheel to see if it will fit.

>>BIRA syays it will take them 6 - 8 weeks to get more brackets. Their

>>anytime soon", even though their site says they have 3. I'm hoping to retain
