    model 3 on track - the need for a good seat (take the poll)

    @MasterC17, I'd love to see photos of the stock seatbelts routed through the OMP Champ-R. I'm also curious about the padding used to increase your comfort in the seat. Is relocating the factory seat heaters (as well as lumbar support) an option? Thanks!

    Seat Back Strength - Racing Harness Ready?

    I talked to HMSMotorsport (the Schroth North American importer) and suggested that Schroth test the Model 3 seats as the vehicle is quite capable and becoming more popular on track. I also talked to them about the Rallye 3 harness and asked them why it wouldn't work with the Hybrid S. They...

    Seat Back Strength - Racing Harness Ready?

    Agreed. I wish the stock seats weren't so darn comfortable (cushion and heat) around town. On track I slide the seat far enough forward to brace myself with my left foot on the dead pedal. And I have to lean the seat farther back from normal to not have my head pushed too far forward with a...

    Seat Back Strength - Racing Harness Ready?

    The geometry of the center cam lock connecting point makes sense for the normal HANS. Still a mystery to me why it would matter for a Hybrid S (as the Hybrid S does require the over shoulder straps to be retained by the headrest, as in the Model 3 stock seat, or the harness strap holes of a...

    Seat Back Strength - Racing Harness Ready?

    I haven't seen anyone discussing the Schroth Rallye 3 ASM harness with the stock seats and a Simpson Hybrid S. I'm interested in HPDE events with the PCA (and potentially other groups) and would like to stop sliding around inside the car. The Rallye 3 looks interesting for the below reasons...

    Track report - Streets of Willow CCW

    Resurrecting this old thread. I've done many track days in the 3. With the stock lack-of-camber and on the stock 20's I get the best tire wear starting at 40psi cold. Yes that's way higher than I assumed I would need. And yes, the outside edges still wear first, but in my tests dropping down...

    CCS Retrofit Availability (2023)

    I received the CCS upgrade today for my 2017 X. I tried CCS charging at two different 50kW chargers and was able to charge at 46kW on each.

    Autobahn CC Joliet IL

    On a 2 mile course I have found that beginners *might* be able to do 4-5 20-30 minute sessions but are better off supercharging over lunch (after the first two 20 minute sessions. An advanced driver can use approximately double the battery of a beginning driver per mile. E.g. 40 minutes of...

    Track week-end comments

    I had a great track weekend for my initial outing after a Carbotech XP10 pad upgrade a couple weekends ago (with 245/45R20 RE-71Rs on the stock wheels.) Upgraded pads made a HUGE difference over stock. On stock brakes one really has to consciously avoid braking hard at the track. On the XP10s...

    MASTER THREAD: Comprehensive Road-Course Modification Guide — Optimizing the 3 for the track

    On the stock PS4S on 20" factory wheels and stock suspension I found 40psi cold was good. (~48psi hot) Lower pressures (~42psi hot) allowed the tire to roll over too much onto the sidewalls. 38psi cold (~47psi hot) worked for RE-71R with stock suspension. There really is a need for more...

    20" Wheel Options

    Odd that shops wouldn't mount the 8.5" wheels on your X considering that the Tesla 19" wheels (the ones sold with winter tires) are 8.5" wide. I'd love to go with a square 20" x 9" setup. Tsportline sells 20" x 9" fronts and 20" x 10" rears (despite the fact that the X only had 10" rears for a...

    Best Tires/Wheels for Tracking Model 3

    This is exactly how my PS4S looked on track day #4. (I'd never driven a car with such little camber on track before so I was not paying enough attention.) I was careful to watch the rollover of the tires closely when I switched to the RE71-R. Compare that to my crazy high 50psi (hot) RE71-R...

    Best Tires/Wheels for Tracking Model 3

    I've never had occasion to install too wide of a tire as I've been unwilling to modify the fenders. Within "what fits" wider has always been better, IME. :) I've run Hoosiers R6 and Wet H20 on another car and they're glorious on track. (glorious = an extra ~.25 - .3 G's worth of cornering...

    Best Tires/Wheels for Tracking Model 3

    I'm curious about that stiffer sway bar(s). One time I found the back end of the car felt unstable under heavy braking with relatively light side to side steering input. (I've since just been careful to not do that but an inexperienced driver could easily bring the car around.) I assume you...
