If and when you do the clutch, i would do the brace and possibly the output shaft then. As long as your not getting wheel hop with the street tires you should be fine. I'm on drag radials with stock clutch and it's working well. It's not that hard of a launch cause i slip the clutch. I'm still in the 1.7 60's for now hoping to work down to the low 1.6s. Not worrying too much myself, but if it breaks it breaks... Luckily if i break my car now i have the whole winter to fix it and i won't be down for next season.

it breaks at stock power level or 887 hp lol, mine broke with the 340 rwhp, but i as running mt et streets i would just wait til my last stock one breaks unless you already have the drivetrain out
I broke my output shaft, ring and pinion, and diff casing with 331rwhp and street tires. Wheel hop will rip these things apart, and anyone who saw the carnage knows it was absolutely DESTROYED. If I had to do it all over my first mods would have been a clutch, rear, and tires.
If you are going to race the car, get at least a good rear with both shafts hardened, along with the brace. Why not spend the extra couple hundred bucks and risk having the other shaft snap? I have an RPM trans and stage II rear and I love it. I just wish I woulda changed out the clutch of all destruction (spec twin) while everything was out.
Perhaps dte has changed their design, but, theyused to use washers as spacers where it bolts to the diff. ECS designed theirs so it wouldn't need spacers. It just fits like it was designed specifically for our cars.
I was going to say just before or just after it breaks. I've done both. I ran 2 years on the stock stuff than added an aftermarket diff before I added any HP and broke it on the third trip to the track. Last Sunday, about 4 years later, broke the output shaft on a stock Z06 diff that replaced the aftermarket one. I did not put in hardened shafts, but will this time.
Rebuilt the trans last winter because I lost 5th & 6th, I would assume that was not race related. Wheel hop does break things but they also break without it as in my case.
here is the description of the product from the ECS site:
The problem of differential case fracture, transmission case breakage and driveline deflection during hard acceleration on the street, road course or drag strip is a common, inherent problem with the C5 Corvette that often shears the differential away from the attachment point at the transmission. A trans / rear brace is the best way to limit the potential for case fracture on your big horsepower corvette.

I know what it is for. I used to have one and took it off. That wasn't the question. I have seen many threads here about broken diffs but I do not recall a single one about a broke tranny case. I suppose you buy stuff from infommercial on TV as well.

Apologize if i came off sarcastic ...... just stating what is in "writing". Over the years i have read many posts and saw the pics to back them up of people breaking both the tranny and rear cases. This was fairly common before and DTE Brace was introduced (in the FI/Nitrous section)
I have one on my car for pure insurance - i dont drag my car that much, but putting down more then enough power to break things. I am not saying my rear will not break, but if it prevents the tranny case from breaking - it is well worth it.

I've heard agruments for and against, but honestly, never seen a post here regarding broken trans case. I have my own reasons for taking it off but would not try to convince anyone not to use it if they want to.
