Depends how grabby your clutch is. If you have something like a centerforce, you'll be driving over your driveshaft at some point. If you do baby the car on the street, it will be okay until you upgrade, but don't dump the clutch (feather it out only), no burnouts, and no powershifting. Or, just put junk street tires on it that won't hook, you'll be fine on them.

The brace won't help you any, either. It's not worth the effort.
