My C63S coupe is slow

Man I just feel the car isn't as fast as I first experienced with it at the dealership. The car has tremendous torque but is rear wheel drive so I feel like the car has trouble putting all those torque fully to the ground, the rear wheels always spins.
Is there anyways I could make the traction better? Changing tires maybe? Do some ECU tuning?

If you're spinning the tires all the time then it isn't a power problem.


Sounds like you might want to get stickier rubber.

If you are still on the stock tires and temps are under 50F the CA will spin like crazy. The rubber is summer only.

I've switched my 285s to 295s in the rear.

Slight increase but the car flys at the right temp.

Tires need to up to temp, ambient temps need to be good, etc.

Also, brand new tires have to get some wear before they hook up in the intended way.

All of which we have no info on.

A car with 500 hp does need to be eased into power in low gears..

Sounds to me like the car you test drove had different tyres to your delivered vehicle.

They are factory fitted with different types not all the same, FYI you may want to go back and check what that car had fitted, otherwise just upgrade as most people do

You are just used to the car now, traction issues notwithstanding. Happens to everyone. Get some new rubber, your butt will be puckering again in no time.

You should go take a driving class and learn how to use all the power you have. This is an honest suggestion I am not trying to be a douche. If you're not used to it you need to learn how to drive the car. Hence the reason my wife hasn't driven my car yet.. one of the reasons for buying this car is losing the back end. If you don't enjoy that then the car isn't for you. Sell it and get an AWD or buy bigger wheels and 305's

I guess it's all perspective... I've had my C43 for a month and haven't fully opened it up
(trying to do a semi easy break in at least) and coming from my Infinit G37 it feels extremely fast. Never driven a C63 but that will change this summer at the AMG driving academy.

I will say I am becomming more and more unimpressed with the stock Continental run flats (feels too firm and too slidy/squishy at the same time), maybe try a different tire?
