What's going to break? For the first time since I built my new motor (about 2 years ago) I'm going to the track. I just got my MT ET streets mounted yesterday so I'm sure something will break. I've never run this car on slicks so I'm not really sure what to expect. I'm guessing either the rear end or tranny will go first. My tranny has a mild shift kit and fresh rebuild and I'm still running a 10 bolt rear. I have Moser axles and a Trickflow girdle cover. This is also an LS1 rear not LT1 if that matters. I know this is a stupid post but I'm just really bored today.

I really don't think anything is going to break but you never know. I drive this car every day and it seems to hold up fine on the street but like I said I never ran it on slicks. I'm hoping everything goes smooth and I get decent times. I'm pretty much just going over everything so if something does break it's not my fault for stupidity. lol.

With an A4 and you're power level, if that rear is in good shape (sounds like it is) you'll more than likely be fine. The majority of my stock 10-bolt failures occurred on the street under less-than-desirable conditions, or just abuse.
If something does fail...I'd say 80% chance being your ring/pinion; 20% your input sprag.

I highly doubt anything will break. Just remember if the car wheel hops at all then let out of it because that's what will break parts. I have a untouched 10-bolt with 3.73's that has seen 1.5-1.6 60' and sixty foot times for the past two years with both ET Streets and ET Street Radials. If anyone beats the hell out of their car it would be me so I wouldn't be too worried. If you have a trans cooler the transmission should be fine. Something I would soon address if you haven't already would be relocating the torque arm off the tailhousing of the transmission and onto the transmission crossmember, UMI makes a really nice piece that I bought about a year ago, works great.

I already went through a 10 bolt and a tranny so I'm hoping I get lucky. My stock 10 bolt died when I just had some bolt-ons and my tranny blew apart right after I finished breaking my new motor in.

I've broke 5 rears....Trust me it's a crap shoot. First set of gears (3.73's) I had professionally installed. After that I just did it myself. I had an install kit, all new bearings TA cover, you name it....I got it. It still broke my 2nd time to the track. I have broke 3.42's and 3.73's. The only gear that stays together is the factory 2.73's lol. It has almost always been the ring and pinion. In all fairness a couple times has not been the gears fault. Once I broke the transmission and once I broke the drive shaft and torque arm....the gears did not seem to like that to much.
