And a set of drag radials will make your track life much more fun. My super big 345 Invos are terrible on the drag strip, not much better than runflats, and my 555RII's were likewise terrible. I believe the NT05 is also a road course tire, so I'd expect it to be similarly less than optimal for the drag strip.
After drag radials, a stall converter will be be the best mod you can put on for track use.
BTW I bet the car looks great with the ZR1 kit...I just did the Grand Sport kit myself and absolutely love the new look. It's like a new car!

On the contrary, street tires will have much more of a tendency to introduce wheel hop which will do more damage on those components as compared to a clean launch with drag radials. With 73K on my car I'm still running my stock axles and a stock driveshaft (I had to replace mine only because I bent the front shaft during the LS7 swap).
The diff I'm running in the car is from a Z06 and is pretty much bulletproof but I don't know how that'll compare to yours.

Never had a problem with Hoosier's or BFG drag radials and when I had the car I made 466rwhp/411ftlbs with a C6 A6. Cut 1.53 60ft and ran 10.844@125.83mphSubfloor, LS1LT1, myself, and pretty much all the people in this thread have run real drag radials. Hoosier's being on the top of the drag radial list.
Forget what you heard and listen to all that really have raced their C6 A6's in this thread.

I've seen more rears break from street tires wheel hopping than I have with drag radials. My drag radials at 18 psi don't wheel hop at all.OP you have an auto, you don't need to worry about your rear so much. But regardless, if you have wheel hop, let out.
One thing....
Sub, chime in on that problem with A6's spinning upon launch, then rehooking and downshifting to first and over revving? Or was that just Hoxxoh who had that problem.

13.1-13.2 is what i was running before during the summer when i had ported intake,tb,headers,exhaust at sir and dynoed 370hp. i have gotten it all the way down to 12.5 with great wheather and track prep and was told it could even be better with tires! something does not add up? my car has to be faster than that. I personally think my car would run a 12 sec quarter mile any day no matter the conditions. when i first got the car it ran a 13.5 at sir at 110 i believe and that was during the summer as well. so since stock the added total of 110hp more and 90 more ft tq should easliy make it 1 sec faster than my slowest time even on a really crappy day right?

I never had that happen. Must have been something with Hoxxoh's tune. Maybe if your cruising and nail the throttle it would downshift, but I never had that happen at the track and I had plenty of passes under me.

no rotors or brakes from z06 put on. just the stock z51 brakes and rotors still on! i know it can affect performance but my traction was usless after head and cam install and i though bigger tires would compliment it perfect so i went with stock z06 rims sizes and did the kit so it would not look funny and of course those great looks were just as much a factor

Not with a stock torque converter. And I've seen +4000 and higher DA at Atco too ya know. 
True. But I think it might depend on the temps (and even the trans, manual or auto), I've found 555Rs virtually useless under 45-50 degrees and that was with only 335rwhp.
I know almost any drag radial will start to go away in freezing temps but the 555Rs seemed to go much sooner. But in warmer weather I agree that they can do very well.

Of course the "Stock" converter has a lot to do with it... and if I ever decide to go to a 3600 I will have to change tires to MT or something = to them...
With the stock converter she was in the 12.3's @ 114 mph DEEP STAGING.. if she went in shallow I'm betting it would run 12.0x

Tom will probably chime in here, but from what I remember he got pretty bad wheel spin, let up to try and get the car back under control and then erroneously put his foot back on the gas causing it to downshift and subquently over-rev.
The general rule of thumb with the A6 should be that if you have to take your foot off the gas completely to control the wheelspin then I would suggest just aborting the run. If however you only need to back off a bit but never remove your foot completely then you're usually okay to stay in it for the remainder of the run.

We're still getting pretty decent air for the Saturday morning Test & Tunes in Sacramento. While the DA hasn't gone negative recently, if you feel like making the trip up here I can almost guarantee I'd send you home with a 10 second timeslip.

You have a very nice setup.
I think even in the heat you'll be running low 12's. Get a converter and high 11's.

I think he has a stock converter...Not sure he would get 10's without a after-market converter?

In that case, just plan to get here late Friday afternoon and then we'll install one that night and hit the track the next day. It only takes about 4-1/2 hours to do and I'll cut you a deal on the installation cost since you'll be driving from such a difference.
Or not, just a thought...

You can't beat that offer! I would take Subfloor up on his offer...Very cool.
