thanks mcbarnet007 - yeah I'm working with my local mechanic and very familiar with Endless products - use them on my other track cars - we'll be going that route - Mountain Pass also recommends them! I was hopiong to do 1 day with stock pads - then swap them out and get some A/B data to post - but apparently the stocks pads aren't up the task - so we'll just do "b" - LOL
@mcbarnet007 mechanic is telling me endless pads lack “fitment tabs” for the model 3 and make some noise on bumps and usage - is this your experience?
Yes, the rear pads from Endless lack the spring tabs that the stock rear pads have to keep them from dragging on the rotor. My driver's side rear lightly squeaks when moving forward at speeds below 20mph. This isn't uncommon for more aggressive/track-oriented pads. I'll be trying to fix that this weekend and will update if I find a solution.@mcbarnet007 mechanic is telling me endless pads lack “fitment tabs” for the model 3 and make some noise on bumps and usage - is this your experience?

The OEM shims are on my endless pads, but one still lightly squeaks about 50% of the time at lower speeds. It's quiet enough that I can only really hear it with the window rolled down. Not a huge deal, but it's more annoying on an electric car that's otherwise silent.
It feels silly when I drive onto base everyday and the gate guards comment on how they love the car but it squeaks as I drive off lol. I think today I might try hammering the shims down better and applying some anti-squeak grease along the tabs.
Two track days on them so far and I'll be doing another tomorrow. Other than the squeaks, they've been great.Have you done a track day on them yet?
This is not my experience at all. Seems like you have problem(s) with your particular car.Summary:
- Track day @ Laguna - car was fun, stock factory compoments not up to the task - quickest times can only be achieved for 3 laps - after that the car needs 'rest' - best time 1:5x.xx on stock tires vs. 1:37.xx for GT3 on stock tires and stock factory gear (track alignment)
- Track day @ Thunderhill - car was fun, upgraded shocks, alignment + brakes (OEM pads), brake fluid - quickest times can only be achieved for 3 laps, after that car needs a rest, best time was 2:17.xx on stock tires vs. 1:58.xx on stock tires stock factory gear (track alignment) - OEM pads melted after a single 20 minute track session - limped car home doing nothing but regen - the OEM pads were literally GONE!
- Track day @ Thunderhill - car was fun, same as #2, new Endless Pads, quickest time achieved only for 3 laps, after that car needs a rest, best time was an impressive 2:11.xx on stock tires vs. 1:58.xx for GT3 (same as above) - tried for 2nd session, but while the car was physically correct - Tesla's software was NOT up to the task - car on track threw 8 different codes and was very very very unhappy
and all the above "faults" dropped the car out of "track mode" - and the car did not recover until after I brought it in and let it sit for 30 minutes…after it's "rest" the car recovered and I drove it home no problem - what went wrong? your guess is as a good as mine, and that is the problem - we just don't know, nor can we learn because the Model 3 is a pretty closed box, and calling Tesla Technical support and saying you're having trouble at the track - they just laugh at you.
- automatic forward braking disabled
- regenerative braking disabled
- automatic brake hold disabled
- stability control disabled (Drive with caution)
- adaptive cruise control disable (not needed/used on track)
- autopilot lane keeping disabled (not needed/used on track)
- rear facing backup camera offline
- brake overheat - reduced braking effectiveness
I have several conclusions in no particular order
- the Model 3 can be competitive for a "time trial" - one lap out, flying lap #1, flying lap #2
- a competitive Model 3 Performacne requires extensive modifications & preparation to achieve these numbers - way beyond the mods you need for porsche
- the Model 3 has NO stamina for a common 25 minute track day session - 4 laps is all you get - cool down on track - and you get another 3 laps - it can not run full pace for the entire 25 minutes
- the Model 3 does not have enough battery capacity for a serious track day with out fast chargers at the track - 60% battery usage @ Thunderhill for one 25 minute session - typical track day is 5 25 minute sessions
- Tesla's software is too fragile and will freak out after extensive tracking - extensive being defined as two sessions - I cut my 3rd track day short due to a vast number of software faults robbing me of confidence since I wasn't quite sure what state the car was in given all the warnings - I had limited support/tools at the track to properly diagnose the problems to determine what exactly was the problem - given that it's my daily driver - pack it up and bring it home - I have neither the time or access to sufficient technical information or tools to fully diagnose/fix Tesla problems at the track - it's still very very much a "black box"
- The Model 3 can be super quick for it's size and weight - but ultimately my conclusion is it's a got a long ways to go still
- _IF_ the Model 3 is quick out on track - just wait a bit - that problem will fix itself in one of three ways
- performance will start to taper due to extended use
- the car will come off track because it's almost out battery juice and will be unavailable for the next 2 hours while the owner leaves the track for fast charging
- the car's performance will be reduced because Tesla's software will be throwing codes left and right and distracting the driver from optimal performance
I am giving up tracking my Model 3 Performance - but will keep the track bits on it- and understand that when I trailer my track car (my GT3) to a track day it's why I have a track car - I will drive to the track in the best sub $60,000 EV using auto-pilot and a car pool sticker. If it tickels my fancy I might take my Model 3 our for 3 or 4 laps and surprise a few of the slower drivers at said track day. But I'll keep it a secret that that it can only do it for 3 or 4 laps, and that now I've used so much battery that I'm not sure how I'm going to get home.
- the Model 3 is a tantalizing sample of what EV's could be on track - and they are coming, and they will be quick, but there is more iteration required
- casual tracking of a Model 3 will lead to disappointment - it's just not there
- concerted effort can be brought to bear and you can track a model 3 if you're willing to endure some pain/disappointment for moments of outstanding glory that will surprise and confound the petrol head - but optimal results required that you show up with crew, have replaced most of the factory bits, have experienced team members, you work around Tesla's lack of robust software, and that you have time to iterate alignemnt, brakes, fluids, pads, tries, pressures and solve the at track fast charging problem, and that weather and conditions are just right
