Mine is a 2018 Model 3 Performance with about 29K miles.
I'm planning to do a HPDE at Grattan Raceway in Michigan in late April. I will Supercharge only at lunchtime, which will require ~2 hours including drive time. So, I'll probably get 3 20-minute sessions each day. I can run 1, 2 or 3 days - it's my call on that.
I'm not willing to completely demolish the OEM PS4 tires, meaning I'll stop running if I see they're about to chunk.
I'm getting stainless steel brake lines and will install new Castrol SRF fluid.
Those of you who have actually run on the track, do you think I can get by with the OEM brake pads given the above conditions?
Keep the PS4 pressures at 36 at the lowest, they do not like low pressures and will chunk fast.
The stock pads are ok on the track but are not track pads they are EV pads and if you are replacing fluid I'd do pads too. If you use them hard you will cook them, though you will get warnings. I recommend the Unplugged pads a good street/track combo. There are also many other compounds that may be cheaper. Its $600 well spent imo.
The rears are actually quite stressed simply because of how hard they work as the E-diff.
Have a blast and know that if you engage track mode you absolutely can lose control. Be ready for that and slowly find the limits if you don't have much track experience. At Laguna Seca I forgot that the last time I used track mode I put it on "Drift Mode"
When I engaged track mode I missed that the sliders were set to -10 TC and full rear bias. I promptly spun and puckered myself.
