OEM Tunnel Brace

[PDXSSCE]

I saw posts regarding aftermarket parts, but didn't see anything regarding the OEM part(s).
Do the convertibles have an OEM tunnel brace like the coupes?
If so, is the part identical?

My guess is it would be the same, here is a link to an aftermarket one that lists for all models

The verts have additional bracing like that compared to the coupes. Some interfere with mid-pipe upgrades to 3". Why do you ask?

I ask because of the following thread:

I'm wondering if it's something my car could use & if so would it fit?

The coupe and vert brace are identical. the vert has a second brace with 8 mounting holes further towards the front of the car. Any tunnel brace fits either chassis.

Nice stout piece. I wonder if you could feel the difference. Here's the ARH brace I considered in order to add their 3" midpipe but the hp/$ equation wasn't attractive. This "chromoly" tubing brace with multiple anchor points should be an improvement over the OE stamped steel.

You've all been very helpful.

The ARH brace pictured is a nice piece, it would replace both braces on the vert, the coupe has the holes for the front vert tunnel brace, which the ARH brace uses. The difference, however, is negligible. Most won't feel a difference in chassis stiffness. The tunnel braces under the car from the OEM are to resist collapse during a side impact. These cars are very stiff from the factory, the only reason to add bracing is using R-compound rubber in a track setting. The vert only requires additional bracing because there is no roof structure to resist flexing under load.

What's your thought of the OEM brace pictures in the OP?

It does what it is supposed to do, which is resist forces that would let the trans tunnel collapse in a side collision. You car has one stock, so i'm not sure what you are needing to know?

I guess the more direct question, is if there's something to be gained in handling by replacing it with a sturdier one?

[2012LS3VERT]

Nothing that you will notice unless you are running race tires. I've tried several different designs on mine. The car doesn't flex in that direction, and the mount points are too lose together to stiffen anything other than the small section of trans tunnel.

But, the guy fabbing them is only asking $15 to cover his shipping cost. So.....

Given your interest, why not get one, try it out, and give us a review?
