Attention first gen JCW owners...
I've got an 06 MCS non jcw that I just installed a 15% pulley on. I also have a CAI and cat-back exhaust. I always thought I had a strong motor but now this thing just rips! I also have factory LSD on it. If I'm going 15 mph and floor it, it spins the tires all the way through first gear and a good amount of second. From 70 to 110 it pulls so hard and fast, it seems like a totally different car. I've got 18" Hankook k106 tires on it so it should be getting good traction.My question is; do your jcw cars smoke the tires this easily? If so, how do these guys with even more power launch their cars other than maybe some serious backpedaling? One of my other cars is a Viper so I have experience with fast cars.

Front. Wheel. Drive.
The simple physics of it is that when you apply power, weight transfers rearward. In FWD cars, this equates to a reduction in available grip, while in RWD it means grip increases. In a nutshell, this is why your Viper can have 2-3x more power and not vaporize the tires every time you touch the gas.
I can't compare to a JCW, but I will admit that the first time I drove a (100% bone stock) MCS, I was appalled at how easy it was to spin the tires compared to the RWD cars I'm used to driving. My LSD-equipped 944 weighs about the same as a MCS and puts out roughly the same HP, and I could honestly work up a sweat trying to get the tires to spin like that.

OP - First, the k106 is not a particularly high performance tire, so that is part of the problem... they LOOK the part, but... (see post above mine to this effect).
Second, are you running JCW suspension or aftermarket firmer suspension? This would help reduce some of the rearward weight transfer during acceleration, which will give you more traction to launch up front. Glad you are enjoying the newfound power though!

No worries Chad1140.
I think you would agree that Mini Coopers are not really designed to be compared to V6/V8/V10/V12's or any derivative with nitrous. I come from a muscle car family and what Mini's are are fast urban cars with great handling that also minimize our environmental impact as well (because even when you drive it like you stole it, it still gets 25 City MPG).
I love V8's but Mini's are basically 85% of the fun of any big engine with 3 times the fuel efficiency + side perks, like finding parking spots anywhere "fast".

To Bad Chad 1140...
Drank my haterade this afternoon. One of my other cars is a Viper, not allegedly. I wasn't comparing the Mini's speed to that of the Viper, but my Mini will smoke my 740. All I was saying is that my mini is much faster now and has trouble getting traction all through first gear and part of second. The only reason I made reference to my Viper was to show that I am used to fast cars and how to launch them. So come on and learn how to read ,you bonehead, before you try to berate someone on a forum who is legitimate. Also my mods are CAI,pulley,unichip all installed by myself among others.

I do have limited slip from the factory. I ordered the car with it brand new. I thought Hankook tires with traction grade A would grip fine, and they did until I added the mods recently. To Myke@RPI, you sound like a jealous little kid. As if I'm going to waste my time proving that I have a lot of cars to a derelict like yourself. You say I have crappy tires, but obviously you don't have a clue as to how much money it takes to maintain nine cars. Get a life!
All I was trying to do was ask a simple question when I started this thread. Thanks for all your kind help.

A rating of A on a Hankook may not = the same A on say a BFG.
Each tire manufacturer has its own philosophy about UTQG ratings. Some view the rating as a huge marketing tool, while others tend to think of it as an implied warranty. Be cautious when you compare ratings - they may not be "apples to apples".
Also how old are the tires?
How many heat cycles?
Where do you live, being fall the roads may be cold and less grippy?
What type of road surface?
Those tire ratings...worth as much as the electrons used to type this message...

Then why not sell one of your cars since you cant buy the proper tires and I am not a jealous kid... By the way you are talking you sound like a high-schooler who doesn't know what he is talking about... The M5 in my signiture will smoke any one of your cars... guarantee... if you are ever in the L.A. area, we can see what your "Viper" or whatever else you have can do... Maybe ill bring out one of the Shop cars...

The tires are one year old with about 5,000 miles on them. I only run them from early spring to late fall. Surface is blacktop or concrete, and doesn't seem to make any difference. Also, it's been 70's to low 80's until the last month. All I can figure is maybe the rubber isn't as soft as some to get better wear rating. All in all, not a big deal and thanks for your considerate concern.
