Critique my spin please

I have difficulty with unloading springs, but that's the fun of practising. I have progressed to doing this on an auto-X track, but hopefully I won't have to at 80mph on a full track. That means something has gone wrong...and once is enough...

Yeah, 80mph is only fun after the sesson. Not too fun while in the moment.

That's a good quote to remember!

Sounds like everyone is on the same page.

I will say this: The M3 is much more conducive to the "catch and release" steering method versus the C6Z chassis. I "think" that the Z06 has less weight, and less feedback through the steering. It's hard to boss it around like the e9x chassis and get away with it.

Once you realized that an oops took place, you reacted very well by not panicking. The early turn-in and complete lift-off at initial over-steer is what contributed to the spin. Once you passed the point of no return, how come you didn't brake? Or, does the telemetry not show that?

I have found neutral throttle to be very helpful on the C6Z chassis in these situations, too much throttle will very quickly get you in trouble (as you might know). Considering the conditions, I would have turned in later and used less throttle at the entrance to the turn. You started to over-steer before apex. Also, you did start to saw the wheel back and forth initially, almost like you were trying to deal with understeer..just an observation.

I know that someone mentioned engine rpm not really being a factor, but with the LS7, at 2500 rpm you're sending close to 400lb/ft of torque through the rear wheels. It makes it "interesting" to accelerate in the wet sometimes.

edit: The Z actually has about 8 degrees of caster..

Good feedback! My telemetry doesn't report brake data. I actually had both feet in once I knew I was spinning like on ice!

The BMW Pugetsound chapter also have a Car Control day at Bremerton as well. If you want to practice, get out to K1speed and do it once a month to practice catching the kart.

When I in Seattle in 07, I think the kart track was being built at PR. If you need to fine tune your driving skills, karting is where it's at.
