My car has had a dte transaxle brace on it since when I bought it (c5z, about 380whp) but I often wonder if it is just extra dead weight. Do transaxle braces really provide any benefit in road course applications that do not see the shock loading that drag cars do?

Any feedback on this guys?

Last C5

With 380 rwhp and plans to road race, I would say it's dead weight.

I would have to respectfully disagree. Ever watched the shifter in an in-car video of c5's on a road course, with sticky tires? I would think that anything you can do to stiffen the engine-tt-diff would be a good thing.

Plus, "ballast" isn't dead weight.

what's it weigh?

Dead weight....

In all of the time we have been road racing these we have never once seen the diff try to depart from the trans. We have however, seen the diff try to break through the side case of the diff. All of the billet side covers, braces, supports in the world wouldn't stop it from breaking the main case of the diff and the only real option we had was going to the ZR1 diff in all of the cars and just cycling them out after 4-5 races to keep them from breaking.


Keep in mind we were on a full slick, but the cars ranged from 400-500 rwhp depending on class.

Depends on your level of car prep. I would love to have one on my car. What better place can you add weight when you need it and it not be considered ballast per the rule book?

At first I thought you were talking about the pfadt-type diff braces:

I'd still not remove it if you plan to truly get near min comp weight.
