Wheel hop - C6 with A6
Should I be worried about getting wheel hop? I am scared (really can't afford) to blow the rear and I am in the process of the build so adding Pfadt engine and transmission mounts now is cheaper than later.
Wondering how the F55 shocks compare to coilovers or adjustables.
Build plan in the signature. Running stock run flats for now, plan to move to stock 18" front wheels widened to 10.5" by Weldcraft with MT 305/35 ET Street IIs, but only if I need to for wheel hop or for a better ET.
Hope to get in the 10s with a reasonably streetable NA build.

Go with Bilstein sport shocks and poly bushings. You may also look into getting a RPM differential with C6Z output shafts, they're far stronger than our stock A6 parts. That's what I did (upgraded to 3.42 RPM gears with C6Z output shafts).

I had never encountered wheel hop until I installed my 427, then it was like I could not
get on it at all, my Toyos T1r did their job with the H/C Headers motor.
so now I'm waiting for my 18x11 wheels to come back from the Powder Coater so I can mount my r888 305/35zr18 and try again!!!!

10s can be run without touching the rear on an A6. One of the nice things about an A6 and drag radials is that the A6 is not as hard on the car at launch and the DRs have a little give in them to help absorb driveline shock.
Running 10s on runcraps is very hard to do. You'll want the drag radials. Coilovers are expensive and unnecessary to run 10s.
If he has the F55 suspension, he doesn't want to toss out the shocks.

My car with Michelin PS2s in 285/35R19 Wheelhopped so bad it felt like it was going to break apart. I got rid of those for a set of 18" diameter Nitto 555R2s on the back, and now not only is it very difficult to break them lose, but when they do, they make the most awesome tire screeching sound ever, with ZERO hop... I am a huge believer in 18" tires now!

So I am now doing the Bilsteins for the improvement in handling that they offer, and also because my stock shocks are at 45K miles now. I'm pairing them up with a C6 Z06 rear swaybar to balance out some of the formidable grip those 305 width R compounds produce on the back!

What makes you think that a set of bilsteins are better than the F55? That is the whole point of spending for that option is to get the shocks. I've seen several demos showing that the F55 seems to do very well at keeping the car planted at speed, but I'm not a 100% sure on launch.
If you are replacing shocks for the purpose of drag racing, I'd look for QA1's if they make them for the vette. They work well in weight transfer situations because you can dial in each corner.

i haven't made a ton of passes, but with about 15 passes under my belt, and 8k miles on the car, i haven't experienced wheel hop once, not on the runflats, not on the invos, not on my 335/30/18 hoosier drag radials, and not in the last 2 days on the 345/35/18 m&h drag radials
because you can throw the 2k f55 suspension away
autos don't hit the drivetrain no where near as hard as stick cars
