Can't beat the pesky Viper
My friend had a 97 GTS coupe, with some bolt ons it was a solid 11 second car trapping over 123mph. I am sure your friend's viper with the mods is trapping the same.

The C63 can more than hold its own against the "big boy" CTS-V. I have eaten several of those for breakfast on both the street and at the strip. Granted they were minimally modded beyond stock (exhaust, pump gas tune, etc), but then again so am I with only a tune and exhaust.
I am happy to just hang with a Viper in my 4 door grocery getter, that I can comfortable drive across the country if I wanted to with my bags in the back seat.
Not to mention when the po po roll up they are all over that Viper before even looking my way. Poser indeed.

The CTS-V is a great car with huge potential. But Its very close to a C63 both with minor mods.
The viper was going to the shop for headers today, I was following in a truck and GTR pulls up.. We all merge onto the freeway and they both get into it... Viper was slowly walking on the GTR.. But it was verrryy close.
Headers, tune and tires (R6's 255 front and 295 rear on 19 pound Forgestars) and you will leave the piggy V on a road course. If the V has pulley and tune he will heatsoak before the tires and brakes warm up.
Big Boys ???????? Gimme a break
Torque is acceleration, hp is top end. No shame in losing to an 8 litre Viper. He's got at least 100 ft lbs of torque up on you.

If only it were true and you could do with out rubbing all the time. Given the C63 Front Engine RWD the car need at least 315 or 335 in back to hook up and not be all tail happy in the turns. I've got 315 on the back end of a Porsche Turbo and it eats them like pretzels
Size 295/30ZR18
Load Range UTQG Max LLMax Load = 1,235 lbs
Max psi = 44 psi
Treadwear: 40
Weight 24 lbs.
RimWidth 9.5-11"
Overall Diam. 25.3"
It's a lot of tire but within spec's. 17mm pads and small tire diameter provide the clearance. Can not take more than one passenger or it will rub severely.

Interesting.... Are you on stock suspension? Did you have to do any bodywork to your rear fenders?
I'm completely OEM and the difference in traction going from 255 -> 275s was staggering... makes me really curious about finding ways to get more rubber on the back.
My C63 is, in my opinion, the BEST four-door sports sedan, daily driver, sleeper beast available (within my budget).
My GT500 is, in my opinion, the BEST example of raw American horsepower and torque, not a great daily driver but the most fun and best sounding car available (within my budget).
The GT500 is faster and better handling than the C63, but that's only because it is MUCH MUCH easier and MUCH cheaper to mod.

How sad is it that a true LT/Tune Only full weight C63 such as mine is faster than every single CTS-V with full bolt-ons and pulleys?
And the few that are faster all have internal engine work/nitrous/race gas?
While I will say you are correct about the anemic rear tires I can't help but think that the rest of that statement was intended for describing the CTS-V itself....
"Porky Curb Weight" CTS-V 4300lbs vs C63 3924lbs

"Iffy Transmission" Please don't get me started on how garbage the 6L80 trans is. I have 200+ passes on my stock trans. I haven't broke it yet.
