[urq] Firewall brace for clutch/master cyl.

[Brandon Rogers]

I was unable to pull up the ebay part -
I've seen the firewall flex - especially with older, stiffer clutches and
or/crustier cars. 
I've had the formerly Jeff now 034 firewall brace on my car for a few years
- wonderful piece - very effective - a must for all ur-quattros.

You have an edge on me as my German is nearly non-existent ... especially on
technical terms ... but I did use some on-line resources to try to figure
things out:

	Spritzwand => firewall
	Verstärkungsblech => reinforcement sheet

... the eBay ad's title indicates that the part is intended for an urq:

	"Kupplungsverstärkungsblech f Audi 80 90 Ur- quattro T85"

Based on your statement it sounds like Jeff's part is indeed a firewall
stiffener of some sort ... from hearing a description I thought that it
connected the firewall to the pedal mount ... apparently that is a mistaken
impression.  

My personal preference would be for something that connected the pedal mount
to the clutch M/C ... and if the 034M part does not do this I'd be tempted
to try the other part.

Well, first let me say I'm sorry that I had to include the body of Steve's
reply in my reply, but that's how my Blackberry works. I bought the clutch
master brace from Jeff a few years back, so I'm pretty confident the two are
NOT the same. 

Besides, the German Description in no way mentions the clutch master
cylinder -- and you know how accurate those Germans are...

.... not sure I agree Ingo ... but then I don't know.  I'll forward the
message to Jeff (the person who designed and first manufactured the part
Javad sells) for his thoughts.  

The problem which causes the firewall failures is exactly that the clutch
M/C is attached to the firewall ... as the clutch is depressed the same
force required to force the clutch open is pushing the firewall forward.
When the car is new the force is fairly light, but as the clutch wears the
force gets higher ... as does the stress on the firewall.  Over time the
bending back and forth weakens the sheet metal that the firewall is made
from and it cracks.  Audi's solution to this problem (at least on the T44
and V8) was to mount the master cylinder to the pedal mounting casting.  

Without having used either product it is a little difficult to see how they
are installed ... but they should attach to the clutch M/C mounting bolts
and the bracket the pedals are mounted to to carry the pedal force.  Funny,
I think I can visualize how the eBay part works ... I think Jeff's part may
attach to the bracketry attached to the steering column.  I suspect the
difference in price is that the 034M part is machined from billet, where the
other part appears to be stamped.  I know Jeff's part can be installed
without disconnecting the clutch pedal linkage, it looks like the other part
with require the linkage be disconnected.

Two totally different parts. The ebay one is a clutch strengthening piece
and appears to be for the clutch mechanism itself -- not a firewall brace!

If you look at both pictures it's hard to believe they are build for the
same purpose, can 
anyone technically explain why they look so different? Price is also
different lol.
