I have a model 3 performance. In the EVX class.
I have a Autocrossed it for 2 years. I have multiple SCCA Champ tour and Pro Solo Trophies in other cars.
With MPP coilovers, front and rear camber arms, sways, 18x10.5" wheels and 285 RE71r.
I have accidentally ran it in normal mode multiple times, and times are essentially the same. I have tried many different settings with track mode, and for auto cross, 50:50 still turns out to be the fastest. I have tried Stability from -10 to -2, and actually like -3 to -2.
Summary is, with appropriate tires, camber, and suspension, I do not feel the track mode is that important. But tires, camber, and roll stiffness are the key. I ran it once in Stock form with the stock tires and it felt horrible.
My Plaid will be here next week. First thing will be to work on the brakes. They need to be able to handle the heat better, which will need bigger rotors. I am not a big fan of carbon rotors, but that is mainly for track use because with lots of heat they do wear and are expensive to replace. However, for the plaid, the may be a good option for daily use and maybe the odd track day.
The brakes on this car getting killed. But believing that track mode is going to solve this problem is a fallacy. Look at the size of the calipers compared to the weight of the car and compare this to other performance occurs. They are not even in the realm of what they need to be.
The Unplugged Randy Probst car that they ran Pikes Peak in and Laguna Seca has:
- massive aero
- CF front brakes and looks to have rear calipers that are different and don't use the integrated parking brake.
- Front upper control arms (in development and should be out soon for the public)
- Big rear sway bar (available now)
- Bilstein modified dampers (in development and should be out soon for the public).
I guess they could have modified the computer, but I discussed this with Eric from unplugged and there is no mention of that.
Stability control is only going to come in based on what the suspension is doing. Camber, roll stiffness, and appropriate tires solve that issue.
I have the lap record for a car with doors with a highly modified C6 Z06 at one track, using Hooser A7 tires, suspension, aero, Brembos etc. I left full stability control on, didn't even need track mode as with Hoosier and proper suspension/aero, the car just stuck.
Again, what more do you need to see?
