C63s track tyres
Originaly Posted in the incorrect sub forum thank you BLKROKT for your reply
Hi,This is my first post on this site, I have just taken delivery of a new C63 s with ceramics which will get 4 to 5 track days a year on dry tracks. I have had a fair amount of track time in the past mainly in Lotus’s. Looking forward to lots of fun in this beast which is about twice as heavy and and has three times the power. I have a new spare set of standard AMG rims to mount some track dedicated tyres. It seems that I should go for either an R spec with a wear factor of about 80 ie trofeo R or Sportmaxx Race OR slightly less sticky pilot sport cup 2. Going to Phillip island in the early new year where it should be hot and fast. I am not looking to win competitions or break the car so don’t really want to be putting new sets of tyres on regularly, but do love the speed , I was around 1.57 at the Island in the lotus. Any advice on how this car will perform on the two types of tyre would be appreciated ,cheers.
I would probably go with the Michelin's since you're just going to enjoy some fun and not to "win competitions". The Michelin's are probably 90% as fast as the Trofeo R, but they should last 3x longer.

I run in general supersprint eventsand have a 2001 W208 CLK55 I use as a Track Car and I use Hankook Z221's, Medium Compound (265/35/18) on a 9" rim and have found them to be a better tyre than the AO50's.
Having said that, my best time at the Island was a 1:54:02 with AO50's (Medium Compound) however I managed to have Two Blow-outs on the same day, one at the Southern Loop and the other at the last corner coming onto the main straight and you know how frightening that can be.
Very lucky I wasn't thrown into the wall! I also managed another blow-out on turn one at Sydney Motorsport Park , again with AO50's.
My tyre pressures were as recommended by Yoko, 33 psi hot.
I run the Hankooks at around 38 psi hot.
My best time at PI with the Hankooks was 1:55:06.
I am preparing a 2008 W204 63 for the Track and will be running the same size Z221's on this car as well.
I found that the AO50's don't like the weight of our cars as they have "soft" wall and especially when you have tracks with long fast left handers, the right front tire is under enormous load.
Before the CLK I was running a W124 300CE fitted with a M117 RUF fuel injected engine which all up weighed in at around 1220 Kg's and i found after much trial and error, the Yoko's were the better tyre.
The Medium Compound Hankooks are "wearing" a lot better than the Yoko's.
Don't get me wrong, the Yoko's are a great tyre on lighter cars but just not right for heavier cars.
Hope this info is of some assistance to you.
If it was the "Cup 2" glad to hear the treadwear was minimal. How many more sessions do you think you could get out of it?
