Top recommended performance accessories for the Tesla Model S Plaid?

Honestly, you gotta be really careful taking that Plaid to Laguna Seca with the stock setup. That car is way too heavy for the factory pads and fluid to handle those massive elevation drops. Since youre on a tight timeline and have a 5k budget, I would suggest focusing entirely on the braking system first. You definitely need high-temp fluid like Castrol SRF Racing Brake Fluid and more aggressive pads. I personally use Unplugged Performance Street and Track Brake Pads and they handle the heat soak much better than the OEM stuff. Titanium shims are a decent band-aid but they wont save you from boiling the fluid. You might want to consider the Mountain Pass Performance Front Master Cylinder Brace to firm up that pedal feel. Cooling is a bigger project, so just make sure to pull any air duct covers to let the rotors breathe... just dont stay out for more than a few hard laps at a time.

> Im on a tight timeline and freaking out because the stock setup feels like it's gonna melt. Been thinking about this... In my experience, rotors are the real bottleneck for Plaids on track. I’d grab some GiroDisc Front 2-Piece Floating Rotors to help with heat dissipation. Also, dont overlook the Unplugged Performance Stainless Steel Brake Line Kit for safety. It stops the lines from expanding when the fluid gets scorching, which keeps the pedal feel way more consistent. Safety is priority #1 when youre tossing 5,000 lbs into a corner.

Just catching up on this thread and honestly, I am still pretty disappointed with how the Plaid handles heat out of the box. It is frustrating that such an expensive car needs so much extra work just to feel safe at a place like Laguna. I had issues with my first setup where even with better fluid, the heat soak was just not as good as expected and ruined my session. Since you want to stay under 5k and keep things reliable, here are a few things that actually help without breaking the bank.

• Airflow is your biggest enemy. The stock cooling is honestly a joke for track work. I would suggest getting the Mountain Pass Performance Plaid Brake Cooling Air Deflectors as they are way cheaper than a full ducting kit but actually help direct air to the rotors where it is needed most.
• Handling that weight. The factory alignment is way too soft for heavy braking zones. I found that adding Unplugged Performance Adjustable Front Upper Control Arms allowed for enough negative camber to stop the car from rolling onto the sidewalls, which makes the whole braking process feel way more stable and safe.
• Better grip. If you are still on the stock Michelin 4S, they will get greasy and dangerous after three laps. Look for the Michelin Pilot Sport Cup 2 285/35ZR21 to get much more consistent bite when you are trail braking into turn 2. You should really spend some time reading the track sub-forums on Tesla Motors Club. There is a huge community-driven spreadsheet there that breaks down the thermal limits of the Plaid. It helped me realize that managing the battery temp is just as important as the brakes if you want more than two hot laps.

Late to the party but totally agree on the rotor upgrade. Im really happy with how much titanium shims help too... theyre such a cheap way to keep the heat from cooking your caliper seals during those heavy sessions.

• Definitely add titanium shims to the list.
• Make sure youre bleeding the lines after every single track day. Its a solid way to save some cash for tires later.
