My FRS is equipped with the TRD front strut bar and the TRD brace kit.
The TRD front strut tower bar that's made with carbon fiber right? Supposedly from the "same factory as the LFA". Yeah that bar is cool. In terms of performance, it's honestly a slight improvement. You need to track your car to get the full feel of it.
The TRD brace kit as in the red bars that's mounted on the bottom of the car right? Yeah, my FRS has that too! For those, I can actually feel the improvement on turns for regular driving, but that's probably the placebo effect hitting me. But when you track the car, you will definitely feel it, and I'm pretty sure that's not the placebo effect.
*edit* One more thing, if you order the TRD brace kit, the rear brace bar that goes behind the bumper is not compatible with the FRS. In the US, the bumper brace aka "crash bar" is actually thicker than GT86/86's in other parts of the world.
The TRD brace kit also looks really cool too from the rear if you're exhaust is not too large. My FRS has the triangle TRD exhaust system so it's a little smaller than stock and the two tips of the red braces stick out from the rear and it looks really really cool!
tl;dr for track/auto-X, you will feel a slight improvement with the TRD front strut bar and braces. Then again, it's probably going to be the same with all other brands.
