And further, what idiocy is 10%?? Would you care to quantify this rather odd claim?
Ten percent in what? Slalom speed? No. Skidpad grip? CLK55's was higher in the Car & Driver comparo. Get a grip, and go back to the ricer forums where people with your posting styles belong.

Slower M3 tests from the same site you deliberately did not post:

And of course, you picked the slowest CLK55 test, now didn't you:
Slower CLK55 test you picked:
Another one you intentionally avoided:
Lol, busted being intentionally deceptive again.
Compare these with the CLK55 test results you posted and show me the 10%, jerk:

This with 10mm wider rear tires and an extra gear.
Wow. Now *that* is enough to sway one's purchase decision--for a street car.

But you're an engineer. What does 10mm wider tyres do? Why does an M3 with 19's lap slower than an M3 with 18"s.
Wider tyres doesn't necessarily mean more grip. The important factor is the front tyres 'cos traction isn't an issue on most tracks. I don't know many tracks where on goes to 1st gear.
And with regards the extra gear, only 3 gears are used on a track like Hockenheim.
Just kidding.

but for the 10% claimed by Bestuhnin that also made me laugh, i never seen so much garbage. "55 handles atleast 10% worst then the m3" 10% worse in terms of speed or lateral g's. Pure speed has mainly to do with tyre grip and to lesser extent on C.O.G and suspension setup. There is a general consensus that the M3 handles better (better balance, feeling and control etc) but that is different to absolute cornering speed which is what gives good track times.

On the M3 vs CLK55 debate, let me add my .02 cents since I currently drive a 2004 M3 Cab.
M3 is a great car, excellent handler, and a eye catcher. I LOVE SMG, best of both worlds. Negatives are that I don't especially love the interior. And that is one thing where the MB definately has the advantage.
If money's not an issue I Personally would of loved the CLK55. But $62k for a Cab with the performance the M3 offers is a Steal. Hell my sister-in-laws 05' CLK500 coupe was more expensive than our M.
Either way they are GREAT vehicles for what they do. AMG tons of raw power and torque, with a luxury touch. M3 - Edgey, Linear, Sporty, a cult classic. Can't go wrong either way.
But you're an engineer. What does 10mm wider tyres do? Why does an M3 with 19's lap slower than an M3 with 18"s.
- the 17" handled better than the 16"
- the 18" handled fractionally worse than the 18"
- the 19" handled significantly worse than the 18" and 17"
Iow, they found that the advantage of stiffer sidewalls gained by going to the 17" was negated by going much larger--i.e., what most manufacturers are doing these days is dictated more by marketing than by handling.
And with regards the extra gear, only 3 gears are used on a track like Hockenheim.
??????? Lol, who was it that was lecturing me about physics? In a car being driven at 10/10, traction is an issue, period. If a car's rear tires lose traction coming out of a turn, it will oversteer, slowing its lap times. And 390 lb-ft through 245's will definitely tend to do this. So if the M3 can accelerate out of turns more quickly without oversteer, it would turn faster laps--and its wider tires *and* higher max torque peak of 4,900 rpm (to the CLK55's 3,000 rpm) would also help avoid oversteer, as would its M-lock LSD.
Well on an M3 you can never lose traction in 2nd gear by stomping it, unless its wet. So on a racetrack you will never have traction problems in an M3 on most tracks.
Coming out of a tight turn, you can overtsteer you say. That is true. But most OEM's design their cars to understeer on the limit. The front wheels give up grip before the rears. That's why most RWD's have a staggered setup. Much easier to control understeer.
Now lets say the fronts start to slide & you understeer. Does it matter what's going on in the back? Once the fronts start to slide you have to lift & the excess grip at the rear doesn't matter. You coull have 165's or 305's it wouldn't matter. 10mm wider tyres defintely won't matter.
In fact wider rear tyres lead to more understeer.

And what you seem to be forgetting is that I am talking not about the corner ENTRY, but the corner EXIT, under the application of power.
Here is a page giving tips to reduce oversteer and understeer. One of the tips for reducing oversteer is "install wider rear tires". Gee, looks like Roger Kraus Racing disagrees with you. Write them a nasty letter.
You might also want to read the section entitled "Exit Speed" from pp 26-29 in the book "Going Faster!" from Skip Barber Racing School and send them a nasty letter as well.
How the chassis is setup from the factory is *irrelavent* when there is insufficient rear grip to maintain surface adhesion upon the application of power. When you are driving a car in a 10/10 situation and the inside tire is making only light contact with the road, it is easier to overpower it, and the smaller the contact patch, the higher likelihood of this happening.
In fact wider rear tyres lead to more understeer.
And finally, M&M, I'm really not inclined to get into another meaningless debate with you about handling dynamics, nor do I care to engage in yet another pissing contest with you about M3's vs CLK55's, which given the amount of time you waste trolling here and in other forums seems to be an activity you prefer to actually *driving* your car.
The bottom line is this: if myself or any other CLK55 owner on this forum had wanted an M3, we could have gotten one, along with a second car, in lieu of the CLK55. Or, if track numbers were paramount, we could have spent a bit more and gotten a 996, a far better track car than the M3, or spent far less and gotten a Corvette Z06, which would slaughter any car being discussed here on any given track. But clearly track numbers aren't the highest priority for any of us, including you. And so we did not purchase an M3, and your infantile attempts to "convert" and/or annoy us are simply so much mental masturbation, akin to trying to convince one that blondes are "better" than brunettes or that the religion of your choice is the "one true religion".
The lap times shown in this thread show that when both cars are stock, an M3 can pull a lap time less than 1% faster than a CLK55, which is meaningless in everyday driving or even spirited weekend driving, unless one is a maniac in need of having his license revoked.
Ergo, the ridiculous "10%" claim has been slain and buried. So my work here is finished.

Praise Jesus!!!
Acceleration/Braking
0 - 200 - 0 Km/h m3 23,2 s clk 25,5 s (from ur last link)
thats the difference withought the m3s handling.
I knowyou have never driven anything on the track before, based on what you have been saying you just read things on the net. Ive taken the M3 to the track many times. Im from La, if anyone knows were buttonwillow is. Laps are around 2mins up depending on configuration. The clk 55 would not be within a couple seconds a lap like you guys are claiming. It is going to get killed on the braking. Just the esses would be over a sec faster in the M. Larger rear tires on an M3 wont do nothing but give you understeer, Im surprised MM had to school you on that part. u cant say u have more grip wen ur fronts not turning and your flying off the track. Ok. The times on that website are for the w208 clk 55. A second slower. ahhahaha. yea right. I have a kleeman 430 that will dust a stock 55. But it cant keep up with the M3 ever. I would enjoy haveing some friendly runs with anyone from the LA area. I aint anti benz. Benz people need to learn how to respect M3s, as they are the pinnacle of BMW engineering.
Whoever drove the M3 on the track with oversteer, must have had flared fenders and 305;s in the front wit his 275's in the rear.
I hate breaking down this stuff to dumb kids like u.

Do you hold any records at any track, anywhere? I doubt it.
Have you ever raced professionally? I doubt it.
And the fact remains that even with the track temperature about 12 degrees celsius colder, in the CLK55 Mr. von Saurma was not one second, but 0.6 seconds slower in the CLK55 around Hockenheim, which is about the same length as your Buttonwillow. And running the CLK at seven degrees celsius put it at a HUGE disadvantage to the M3's twenty degree celsius track temperature, as a supremely competent track star like yourself must surely know. It is a fact of physics that tires stiffen in colder temperatures, which is detrimental to their grip. This will affect braking times and distances.
Further, if you weren't so ignorant, you would know that when Car & Driver tested the two cars *AT* Buttonwillow, the lap times they got in the CLK55 were again less than one second apart from the M3.
You can write anecdotes about how with other drivers one car is slower or faster than the other, but I was under this silly impression that the *driver* of a car has, oh, just a teensy little effect upon the time a car can achieve around a track. For example, I would wager that Michael Schumacher could turn a faster time in a Ford pickup truck than you could in your CLK430. Does that make the Ford a better track car?
To get a true measure of both cars' capabilities, they should be tested by the same driver, at the same track, on the same day. In this case, we have two out of three: tracks and driver. The date was different, and dramatically lower track temps give the M3 an advantage, and yet still, the times were within fractions of a percent of another, nothing close to the idiotic ten percent you're claiming. AND when Car & Driver did a direct head to head comparison of the two cars at the same track, the time was, again, less than one second.
Chew on that, troll-boy.
This seems like nothing more than sour grapes because you couldn't swing a CLK55 to me, or an M3, which you seem to like more than your own car.
