SCCA Autocross Class for the Model 3

[SK360]

Ok, thanks. Sorry newb question. Ive only run the Evo this year so far and havent taken out the new Tesla toy to play.

No worries! I mark a fake start/finish line on the map and hit the start button before my run and stop after. It records it to the CSV file as lap 0 since I didn’t cross the line but good enough for AutoX data.

Quick notes as I start diving in to the Tesla... Loosening everything and biasing towards max negative camber I'm at -1.2deg on both front wheels.

Most of this came from the control arm mount biasing inward when tightening. I also disconnected upper control arm, articulated upwards to max height before tightening just to bias preload as much as I can bringing car down.

Certainly not enough for SS competition but better than 0.6 stock.

That is a pretty solid gain (anything to just help the shoulder of the tire!). Can you elaborate on the "control arm mount" and what you did there? When I tightened my shocks on the front I leaned on them while tightening the 3 top bolts but I'm wondering if there is more opportunity for me (I have not measured where my - camber is at)

I used a prybar between the sheetmetal access holes and the stud on the upper arm mount. I biased from one hole while tightening another just to make sure it was maxed out. Then tightening control arm I also biased it all the way in and up at max height. I didnt try loosening the lower control arm and maxing that bias since it will probably get pushed back in under load.

Awesome - Thank you for sharing. I had a Boxster and one thing I loved was that it had actual "slots" where the struts mount so you could actually adjust for camber...A shame the M3 doesn't have that capability
