4kq performance parts

[george nimmer]

I'm looking for a US distributor for the Sparco Aluminum Strut Tower Brace for Audi 4000 quattro.  I can't find anyone who is selling this any more.  Any clues where to find one?

Also, I need a larger rear sway bar.  Even with the center diff locked, I'm getting some understeer (although not nearly as bad as when the center diff is UNlocked).  Blau and 2Bennet sell a modified 22mm unit, but I'm looking for something more like 25mm.  Any leads on this?

I'm running my 4kq in SCCA Solo II (SP class), and need to add a few go-fast parts before the next event.  ;-)

TIA
George
