NOW TAKING ORDERS IN VENDOR'S SECTION!!

Please refer to my thread in the vendors section for pics and info on the final design of the G1 brace and how to order. Here's the thread:

http://www.camaro5.com/forums/showthread.php?t=62586

After installing my 3 inch JBA catback, the stock cross chassis brace (at least thats what I call it) rattled on the larger exhaust tubes, being .500 inch larger of course. The first thing I noticed when getting under my car to do my exhaust was how whimpy it looks. Stamped steel and real thin. So, figured I'd make one myself. I'm a CNC machinist at my father's shop and had a little extra time this weekend.. these are the results.

Basically theres 2 reasons I did this. Main reason was to clear the bigger tubes. Second, my brace flexes ALOT less than the paper thin factory one.. so some added chassis rigidity can't hurt either!

Was going to do a one piece design but didnt have any .500 plate that I liked so I did a 3 piece type deal. Two bases or "risers" and the center plate is bolted with stainless 1/4-20 machine screws. Was going to do SHCS's but didn't have enough depth for a counterbore so went with just standard 82 degree head. I think it turned out nice though. I have it bolted up to the car now and I works perfectly. No more contact with the tubes. Takes about 5 minutes to put on or take off. Next time we have parts going to the plater, I'm going to slip the brace in with them and get it black anodized then go back and skim-cut the chamfers again.

Heres some pics. Let me know what you think.

Nice job. My dad is a CNC machinist also. He's really talented at what he does...

I work there part time but not as a machinist. Where do you work?

We work at a place called Seiler Instruments, we make parts for the army.

We're down in central texas. Been on machines since I was about 15... went full time at 19. I'm 24 now. We do oil and gas, medical, aerospace, computer... and as you can see, automotive stuff on our own time haha.

Pretty damn impressive. You are quite skillful. Thanks for sharing.

It had crossed my mind

i would be down for something like this, then I would just powder coat it and be done. The nice part is clearence for the 3 Inch pipes (that should be going on this week), more rigidity, and better protection for the investment of exhaust... just my .02.

I'd be interested as well. I replaced my resonator/H pipe section with a X pipe and it hits occasionally. Thought about putting a couple washers on there but if you did this for the right price, I'd be interested. I like the look of yours better, lol. The added tunnel rigidity is a bonus.

eynigush · 01-18-2010, 09:38 PM

I'd buy one.

That's some impressive machining!

I know what goes into something like that. Looks Great!

TUNNEL brace. Thats what its called. Not a "cross chassis brace." I'm dumb.

I was also thinking about making some links that would connect to this brace and go all the way over to the each subframe. Was looking under there and there are 2 unused threaded holes on each side and they look lonely.. wanting to be used. Seems like that would really help rigidity.
