Carbon Fiber Exhaust/Chassis Brace with Spacer

So after putting on my new exhaust, my factory exhaust brace didn't clear. Rather than cut the factory brace or add a spacer, or even both. I decided to create a new one.

This is my first carbon fiber attempt. I'm just trying this first then off to my CF intake. I decided to tackle this first because it seemed easier.

The Mold - Factory Brace with wood




Laying the CF

I used the factory brace and added a .25 in wood spacer as a mold. Layered with 3 layers of 6K 2X2 Twill and West System Epoxy.

I have a feeling I'll still have to trim this, but at least I'm not cutting the factory brace.






Too much resin, not enough vaccum!








Cut down


Test fit


Clears by 5mm


I had no clear/gel coat but an extra layer of resin shall do



Other brace options

Oh yeah, Might as well just take it off!

I've been running without that brace for about a month and cant really feel a difference.

But if it's there, I'm sure it has a purpose. So back on it goes!

Looks good! Very interesting, since you don't really see it from an outside perspective.
