With the double fire wall on the A4, does a front strut tower brace provide much, if any, handling benefit?

Being the dual firewall you really wont gain much. The A4 is pretty solid just from that and has a pretty tight ride to begin with. Now I'm not saying that it won't improve at all, but i doubt you'll notice much at all.

The false firewall is not a brace. They have cracked in hard driven cars. I installed a bar from PureMS 5 years ago that stopped the creaking from the cowl flex when pulling into the driveway. That driveway could twist a car pretty good when coming from the downhill direction. With the strut bar, lower bar, h- sport sways, and kw coilovers it would lift a tire for a couple feet.

Lookey what I found! (http://www.audizine.com/forum/showthread.php/105317-Strut-Tower-Braces?highlight=optima+034r)

I've got the LLTEK version. The strut tower bar makes the front end of the car much stiffer. Bigger difference on the a4 b5 than my previous vehicles..wrx and integra. Initial steering response is better and noticeable. Strangely, it also makes it feel as if you've got stiffer front shocks. If you can find one, get it.

In the big turbo a4 I had before my s4 I had a front strut brace from an A6.. took a bit of work but there werent too many strut bar options a few years ago when I did this mod. I liked the feel and really stiffined things up after putting the bar in I also had a few welds laid to fix the areas that were splitting from auto x/hard driving

There is absolutely no way it could hurt you. Anyway to get more rigidity out of the chassis is a good thing. I noticed a better steering response on hard/quick turns.

This is the one, worked well for me and kind of cool to keep it oem/oem+ not sure of how many people know about it

I'm going to try using a .5x2x48" piece of steel ($12 on amazon) with the brackets. Now if only people would call me back about the brackets.

reinforcing the firewall across strut to strut by welding a thicker bar and painting it would suffice as much as a strut bar and cost a heck of alot lower {for do it yourselfers}. the flex that seems to stiffen when people use tower braces on strut mounting points is because the flex in the struts is transferred away by securing the strut bolts, buy 034 urethane strut bushings. one thing i know for fact though is you want some flex, totally stiffening the chassis can cause buckling and actually create a weakpoint. the oem one rocks though for a simpler way.

That is the one I have too. Got it from PureMS in 04 or 05.

I don't think they sell them anymore. Couldn't find it on there. Just gives me a chance to bust out some power tools.

The improved handling is night and day for me. Great piece to get
