Chuckie Strut Tower Brace.

Sat Sep 29 20:24:53 PDT 2007

Guys,

Some miss information there, Chuck Pierce's design uses stock Audi S4 
tower plates and mounts up with the stock 200 Brake reservoir. The rest 
of the parts are source from industrial standard supply and are over 
designed for the application. The cross bar is not a box tube but a 
round steel tube with fairly thick walls. The adjustment bolt with 
reverse threads on opposite ends is standard hardware issue (just need 
to know which hardware story to go to) and treaded into the tube with 
lock nuts on each end (look at a Nissan 350Z for the inspiration).

I used the Chuck Cross bar to push out a collapsing right shock tower to 
get it back  to factory specs. If you can find one or can talk Chuck 
into making some more, you will find it works very, very well.
