My Ride: 330i, 330Ci
I tried a LOT of things back in 2006 to get better traction, and not everything you think would work does.

I remember at one point swapping from a 245 street tire, to a 275 "R" compound and spinning more. I also ran the car down to 10kms left in the tank, then filled the tank up and ran identical ETs, but with a slightly slower MPH.

My favorite was buying a jug of VHT traction compound, and applying it directly to my tires.

I still have the jug.

Tire pressures did help, but only once I figured out how to let out the clutch slowly on launch, and feed in the power. It's a lot harder than it sounds. Basically, I launched at say 1/4 throttle, then progressed to 1/2 throttle while feeding in the clutch. Once the clutch was all the way out, I'd add a little more throttle while "feeling" the tire spin. Most of the time the peddle would be all the way out and I'd have to shift into 2nd....no chance to add more power. 2nd gear was a little easier.

Eventually I got sick of spinning....and moved to slicks.

2009 I had too much traction.
