When we go out and drive in our BMW CCA events, we were told in no certain terms are we to put a wheel or a tire off line, and any ass-hattery will subject you to a ban from the instructor corp in the Pacific Region. I ALWAYS drive during our events with 2/10th in reserve.
The difference in tire wear between 8/10th and 10/10th or 11/10th is HUGE. My rears are typically scrubs from club racer friends, shaved with anywhere between 2-5 heat cycles on them, and they still last about 1.5 seasons and ~10 days because I don't push hard. If I were an attendee and "not embarrass myself" is not a prime directive, I doubt my tires would last nearly as long. But NT-01s and the old RA-1 compound is very much alike in this regard, they last long despite heat cycles and are good to drive on until they cord. PERFECT for DE use. I did 3 sessions on fresh Hoosier R-6es and those are pure crack cocaine. Holy unlimited grip batman. But the difference between the first session and the last session was very apparent.

They must have some different policies in your region than in ours.
Our last driving school at Mid America Motorplex here was a realy wet one. We had at least two instructors go off far enough that the recovery crew didn't have a long enough strap to pull them out!

We don't hold our attendees back. In fact in the Andvanced courses they're often pushed past 10/10th in a controlled manner. We hold our instructors to a very stringent standard. Occasionally I get the urge to sign up as an A+ student just so I can let loose the reigns. I tell ya, the A+ program in our region is a ton of fun.
But there are still plenty to learn at 8/10th, it's just your consumables wear much slower and the risk of getting kicked out of the corp decreases significantly. Plus the incentives for me to drive 10/10th don't come around often enough (say, a buddy instructor in an E46 M3 were to catch up or vice versa). ![]()

Great thread, I've been weighing my options on my next car and the e86m is very tempting again!...
Anybody know how the potential of the z4 35is is like on track? Off topic but, my c6 z06 has proven to be the cheapest on consumables at the track. Rotors are $60, st43 pads $260, qt of 0-30 euro is $6, 25 mpg to track and back, tires last forever bc of the large contact patch and lightweight nature, car is ready to hit the track in stock configuration with very little improvement in times with suspension upgrades unless your thinking of motons. I may have just sold myself back to the z06, damn

Spoke to HMS Motorsport at the Glen last weekend and they summed it up for me. They have built 2 custom roll bars and set setups in Z4s and said that while their customers loved the workmanship, they started to not like the car as much anymore. He said if I enjoy DEs and like the car, I should just keep it stock inside and have fun; if I want to go to the next step with seats, bar, harnesses and HANS, then I should consider getting an e46 M3 or an e36 M3. Having instructed a few students in e92 M3s, I don't have a strong desire for that car anymore (I was planning on getting one as my next car a couple of years ago) just because it does not feel nimble and sprightly as the Z4MC. We'll see what the future brings but for now the Z4MC stays stock inside and I will keep DE'ing it as-is because the more I learn to drive this car closer to the limit, the more fun it becomes. It still challenges me every time I get behind the wheel at a race track. |

255/40/18 Hoosiers on 8.5in rims fit all 4 corners on my z4m provide incredible grip. Running 3deg neg camber up front and 1 rear to make fit. Rolled fenders but didn't need to. What prior post said about the way this car rotates and the feel of the slip angle at high g's has me hooked over my e90 335dinan for track days. I haven't tracked an e46 but cannot go wrong there either. I'm below 3000lbs and pull these easily on straights. But the Dinan is faster than both in straights.

I own a Z4MC... And I say: M3 all the way.
A Much, much, MUCH more BALANCED car. The controllability is WAY better, and it's an easier car to drive fast on the track. That said, I OWN/BOUGHT a Z4MC. It's a handful and has some seriously weird handling characteristics. With you butt hanging over the rear axel, it's an absolute HOOT! IMO it delivers WAY more of a the THRILL than the M3. YMMV. |

Apart from a bit quicker rotation I don't find the m coupe altogether that different from the m3 at the limit. What sort of weird stuff are you talking about?
With 265's or 275's all around they both seem very similar to me. In either car I get tons of communication from both ends of the car so they never seem out of shape or surprising really. |

Thanks for the continued feedback guys. I'm taking steps towards making my M3 a track car while leaving the Z4MC pretty stock.
My wife's been tracking the Z and it'll be a while before she outgrows it being completely stock.
