There is enough flex to require a strut brace. A V8 with a lot of torque can twist a frame pretty quickly.

Yes, since the convertibles don't have a top they inherently have more "flex" than a coupe would.
This is true for just about any convertible, not just the camaro.

This brace helps in keeping the body a little more rigid during cornering.

Just normal straight line driving, you won't notice any difference.
It is when you push the car to its limits where the difference between a coupe and convertible would be noticed.

Look at the undercarriage of each and you will see the convertible has additional bracing there also.

In addition to the strut tower brace, the vert also has a reinforced trans tunnel brace and extra steel under the rear seats for more stiffness and rigidity that the coupes also do not have.

Thank you, gentlemen. I appreciate the answers. I heard many times over the years that convertibles (in general) are heavier than their coupe counterparts. I guess the extra metal underneath to make up for the lack of metal (roof, etc.) up top.

On a uni body car the body is the main structure. Front and rear subframes attach the suspension and drive train to the body. Cut the roof off and you lose the structiral integrity of the body. Hence the need for the additional bracing under the convertible, the tower brace is just part of the bracing needed to control flexing of the body.

Awesome!! Thank you so much for posting this. Funny how the bracket kit is just as much as the strut tower brace itself. Did you install it yourself, or is this a, "leave it to the pros" kind of mod?

I would suggest to leave to a Pro. My mechanic was very surprised when he drilled the towers to install my Hotchkis. You need a very high quality air drill to do the job.

Just finished installing mine. Can't drive it until spring, but that's one more mod off the list for this winter.

Silly question. Are any of you installing washers, or anything underneath it to prevent scratching and possible rust in case it that piece would ever shift or move a bit because of vibration? Just wondering if that would scratch the paint off and then be a candidate for rust at those sport..

I considered doing that to protect the paint, but decided its not going anywhere, it's a $185 part, so I'll leave it on the car if I sell it - no one will see under it.

Hint: If you hit it with a little Mothers Polish, it'll shine like, well, polished aluminum!
