strut tower brace
Well, I just got my tower brace from shark racing and I was wondering if there is anything I need to worry about during the install? Also is there a certain amount I have to torque the bolts on the strut tower?

It's a pretty standard and easy install. Just be sure to leave your knock sensor mounted in the same as it was before you took it off. You'll have to either relocate it, or shave a small part of the metal off to get it to fit. This sensor is the little square sensor that sits on the strut tower on the driver's side. If you mount it any other way than the way it sits now, then you'll lose performance. wink.gif

Lo&Show, Random Is that true about moving the knock sensor?! eek.gif I've been running mine like that for quite a while now and it seemed to run ok. Could someone please take a picture of it how it's supposed to look so I can change mine. Thanks for your help!

Just as long as you have it in the same upright position you should be fine. I Jerry rigged a washer and put it behind the strutbar (cuz mine is from PPSonline, not SR, and the knock sensor wont fit, unless you take a huge chunk outta the bar) by the brake fluid or PS fluid thing, works fine, mine faces the same way, and sits the same, and is still technically on the strut tower, just moved back. I think I should be fine...
Maybe the other guys can shed some more light on it.

Don't know about that "must be upright" statement, KayJai...I haven't had any problems with mine being mounted vertically.
The sensor on the tower brace is actually a comparison sensor for the ECU. This one is listening to the ambient road noise being transmitted through the suspension to the body frame, engine, and everything else connected to it. The ECU uses this as a filter against what the primary knock sensor on the engine block is reading. When you hit a seam in the road, both sensors are going to pick up the "thump." The ECU sees that both sensors registered the noise, and can ignore it because it now knows the engine wasn't knocking. If the engine *was* knocking, then only the sensor on the block would pick up the noise, and then the ECU could respond accordingly.
So long as you have this strut-tower knock sensor located on a flat surface that will allow it to read road noise, it will work fine. I have mine mounted on the metal around the strut tower, veritically. Next time I'm under the hood, I'm going to try and devise a way to mount it directly to the tower brace, which would be a VERY GOOD source to read road noise.
