    Maximum allowed tire width in the class is 255 and only one aerodynamic element is allowed per end. So, either a diffuser, wing, or ducktail. Too bad they don’t allow heavier cars to have wider tires. Also wondering if there is a better 220TW tire than the 300TW PS4S (which make some compromises for comfort and efficiency).
    I see that the winning time for the RWD class was 1:56.2 so I wouldn’t count on 1:59 holding up as the fastest time at this event in the future. The record AWD time is only 1 second slower than RWD (I guess that was with the old tire rules).

    The spacer is probably to clear the suspension. The PUP rotor hats are 5mm thinner so they require 5mm spacers to have the same fitment as the standard brakes.

    Thanks! I guess Cameron's Long Range Model 3 was also Blue. Tricked me! :)

    Lots of people are painting their calipers red to look like the P3D+.
    In this case, he got Track Mode, so you know he’s the real thing.

    Also the 2 minute time. I would be super impressed if the RWD car could do that.

    A proper wing would balance the car perfectly. The rules of the class mean you have to choose between a diffuser or a wing, but not both. We would be interested to see which has a better tradeoff of drag vs. downforce.

    Cameron used a grinder to remove some material off his rear calipers to clear the 18" wheels, then touched it up with red paint.

    That's interesting, I ran a set of same spec wheels without any need to modify. Do you know where the rear caliper was touching?

    A tall wing would operate in the cleanest air but long struts and the endplates would add some drag. A diffuser might be lower drag but lower downforce also. If so, a wing might work better at slower tracks and a diffuser at faster tracks. Raise the corner speeds without too much high speed drag.

    How large can the diffuser be? :)

    Given how clean the airflow is around Model 3, might be able to use a less tall wing relatively near the trunk lid.

    Do you have better pictures of the rear spoiler and the front splitter? Would love to get a better look at those.

    This is the problem with the f'ing chicken *sugar* society we live in today...:(:rolleyes:o_O
    You get beat by better competition, accept your whoopin' like a real man & come back better prepped for next time.
    But no, you'd rather protest & get them DQ'd

    Big ups to @MountainPass and @Odiemac for whooping ass on that coward...:cool::p:D

    The performance brakes also have much larger rotors and look different. So even without a color difference, it's easy to tell.

    The RWD cars are allowed 285 tires all around, so maybe a super lightweight LR car with fender flares would be the hot setup ;)

    Like the BRZ that won the RWD class? :D It was probably running similar power to the STIs.

    Good stuff Sasha and Cameron. I couldn't resist arguing with some trolls in the comments of the video claiming they weren't impressed with the lap times. They tried to cite a stock Civic Type R rolling on RE71r's running a 1:57 at that track, but I had to point out that the RE's are much stickier than the 300TW PS4S and that stock F8x BMW M3's seem to run around 2:03 there. Those times are very good considering how close to stock the Tesla is and the daily driven tires.

    @MountainPass's testing at his home track seemed to indicate that traction at the front was the most lacking due to insufficient camber (and a lack of camber adjustment). Lacking camber adjustment he put wide tires up front and seemed to have better results. Due to the relatively balanced chassis on Model 3, wide rears and narrow fronts may not be as much of an advantage as on other cars and may understeer a lot. YMMV. :)

    I know this has been mentioned a lot but I would totally invest into my RWD if there was a track mode with traction control disabled.

    Just waiting patiently....
