any car will break traction depending on the rev. why would anybody put 295 on a M3, so it can run slower. d

 

So it can get better traction from a stop.

 

yeah but that's a bit excessive for a bolton car. My uncle's dinan sc E36 definetely needs the big beefy tires. He has some sort of M racing wheels that are 18X8 and weighs around 15 pounds, it's nuts

 

I'm talking from off idle not revving.

 

Understanding TCS and traction in general is the best knowledge you can have. TCS is good for everyday driving but not for racing. This is why race prepared cars go with a positive traction locking differential. Most cars have an average TCS system from the factory and depnding on the popularity of the car, you may have a choice for a better aftermarket differential. Tires are a quick fix for traction, once they loose their new "bite" they are no more a cure. Good traction off the line is based on suspension upgrades to transfer more weight to the rear (if the car is RWD) Control arms and torque arms are the most popular bolt on fix. Often times, owners with powerful cars focus on power and not "power delivery" which doesn't allow them to make their best 1/4 mile time.

Here is a neat link that shows you how an electronic TCS differential works if interested.

Yeah right. 323's are not fast in a straight line. By third the WRX should have 3 cars on you unless the WRXer is playing around.

I know this because I owned a 2000 323. It was great in the twisties (w/sport suspension) but terrible on the strip. Best times were high 15's.

FWIW disable the traction control every time you drive. The 2.5 doesn't have enough grunt to break traction hardly ever anyways.

 

who is this directed to? me? :dunno:

but E46 M3 has a trick lsd rear differential. It's variable locking from 0-100% or was it 0-70%? I forget.

 

I know that, but it is a far cry from a Detroit locker in terms of strength or grip. Even with variable lock, it still should be off when you launch in a straight drag style run. I know you realize this, but when you launch, simple is better as far as differentials go because you want all the power transfered to both wheels, not have the car fighting over which wheel will get the drive motion. When people modify cars with either more power or a different gear, the factory electronic TCS differential becomes less effective. However, it is a nice feature for when you are going around a rough turn at a stoplight and walking on the throttle, it really grips.
