Anyone removed the flimsy undercar brace?

[Bigboss]

its a subframe brace to help reduce chassis flex most performance cars have it…

The cardboard that goes on the back of bookshelves is also super flimsy, however is structural once you put in the 40 penny nails . That said, no idea what that brace does

That thing is about as stiff as a beer can.

I expect it's plenty strong under lateral compression and tension.

This obviously doesn't matter to folks who only drive in a straight line.

The bar is there to add rigidity and stability to the chassis when that area is under tension and stress.

It is not supposed to be very rigid because it has to be able to flex the way the chassis does.

You don't feel it because you don't drive the car hard enough. Even on a drag strip these bars improve traction by minimising chassis twisting at launch and full throttling.

That bar adds structural rigidity to the unibody, it is functional and should be left installed. It may seem somewhat flimsy when not installed in the car and so do most of the other stamped components that make up the vehicle structure until they are all welded, glued or bolted in place.

As an engineer who spent several years working in the aviation industry early in my career I analyzed that component when I installed my exhaust and it is structural.

Even the large aluminum plate under the engine is structural. If it was not needed Toyota/BMW would have not engineered it into the vehicle.

And nothing aside from driving in a straight line matters. It’s a win win.

Is there any other option on the market than cusco? I have nothing else on the car that''s blue

I have mine off It does pretty much nothing. I had to remove it for my aftermarket exhaust.

Maybe I should put mine back on and see if I can break it 🫣
I just finished a weekend at Homestead and was really flexing her. Shaved off another 3 seconds to get under 1:40. It’s great running with the newer Vettes and and bigger than Cayman Porsches.

Anyone have a link to the Cusco and will it fit with an aftermarket exhaust (AWE track in my case)?

You can buy it almost anywhere, this is what it looks like:

It fits just fine with my HKS Super Turbo exhaust

And my AWE exhaust, to specifically answer that part.

And with the Magnaflow, any properly designed and engineered exhaust should fit fine with the brace in place…

Damn she’s beefy I gotta have it

Went with RDH Japan... their selection and prices are insane. Got my Blitz bar from them. Mega happy. Appreciate the advice!

 

[SavageGTR34]

I replaced mine with the Cusco

Did the exact same thing when I installed my AWE exhaust

Get it powder coated whatever color you want.

It doesn't bother me that much to pay the extra cost to change colors.
