Raced a C63 with my Z06
E60 M5 curb weight- 4012lbs.
Sorry man but that isn't the case. Less than 100lbs. Plus the wider track, longer wheelbase and tighter transmission of the M5.
As for audi, The S6 is a 430hp pig. It competes with the 550i. RS6 looks good but weights 2.2tonnes compared to 1.8tonnes of the M5.
I do not understand AMG why did they mess up on the tire size... this is one of the most important thigns on the car for handling... I mean even M3 comes with 265 in the rear.... how do the expect a heavy car with 6.3 engine and 440 ft of trq do well with 235 front and 255 rear... such a bs.

I will improve that on my car, 265/75 on the rear is a must, and im sure with PP and slight engine tune... this car will eat up m5's.... I have 2 friends with bmw m5's to beat, they are picking on my C63! And I will do it. after few slight vrp mods!

In this case the V-10 is better then the V-8 if your comparing a M5 to a C63.
I'm not impressed with any non-turbo Audi so I pay no interest to them.
I would put my money on a M5 around a road race course any day if it's racing any stock AMG,even the Black Series
(maybe the 6 even has better dynamics cuz its a coupe)
here is a video of a side by side comparison of the CLK BS vs M6

Bobby ,pm me and let me know when that C63 is out there.
They have cars that wrangle 1800 HP through a 10.5-inch-wide tire. That's equivalent to about a 266mm-wide tire for the metric folk.

Also remember that adding width to the rears without the commensurate bump in front will only exacerbate the factory-installed understeer.
Sticky rubber in OEM sizes also adds grip without penalizing acceleration or braking - unlike heavier, larger tires that add to the unspeakable evil of unsprung weight.
He followed me onto the highway and we did the classic 3 honk race. The first 2 runs I started in 2nd gear. We went from about 45-120 on both of these races. Each time, the C63 would hang with me for a split second and then I'd just pull on him hard.
The 3rd race was at a little lower speeds, around 30mph. I was in 1st gear. I got lots of wheelspin and traction control was fighting to keep the car straight. I pulled him even harder this time and beat him by about 10 lengths. After the race, I gave him a thumbs up and told him to follow me back to the meet, but he kept going. Props to him for running me though.
My impressions are that the C63 is a very, very quick car. I think it could hang with a 996 911 Turbo.

Tires are a must...i laugh at your width (255),with 285 rears on a 55k you still break traction easily!
M5 walking is at higher speeds. Lower is AMG advantage. Dig is AMGs
ChicagoX can wider tires both front and back slow the car down in the straights?
lets say 19 wheels 9inch fronts 11 rears?
Fantastic job, somebody ban this douche.
just for reference SL55 is not the fastest 55 amg car... a sedan is

SL is heavier then some of the sedans out there
days of sedans not been considered sport car contenders is over
an SL65 is a nice car non the less though, and i would jump on it for the power that beast makes
Hell I need my space to race man. I went at it with a C6 Vette the other day in what I considered light traffic and still had to jack on the brakes at 150mph. He had to learn a little respect when cutting off a faster car.
