Awesome! I’ll be in touch with ETAs.

GiroDisc 370mm Rotors Only Ready-to-Install BBK

@Snelson3 has a DIY earlier in the thread. Tools: Time-Sert 1217 M12x1.75x24mm Inserts: Time-Sert 12173 Available from Time-Sert directly, various tool suppliers, or on Amazon.

I should have some feedback from Sonoma next weekend - running same G-LOC R12 compound as the car has been running with P-car brakes.

I had a tab open! M14 x 2 x 50.GM P/N 11570092

I need to head in to the shop for more photos this weekend, but ready to offer this up as a kit for those who do not want to fill their garage with metal shavings while re-threading the calipers or shopping around for parts. Still working on a more elegant bracket solution for the Spiegler...

Need one more order to kick off a production run. 4 to 6 week lead time for rotors from there.

Still working on full kit pricing. Hope to have some updates by end of the week.

Someone decided to take the non-smooth route on the way out. I was worried we would have to get him pulled out because it looked muddy but he survived the off-road excursion. Hope it gets paved soon.

I wonder how many Tesla Corsa participants are just going to drive down that gravel. I will if @buckets0fun will. Track management said “Tesla says it’s not ready, but I definitely see people charging.”

Ideally we would have 4 more commits for a production run for a full production run, but I will stock a few to make that happen if it takes much longer. Update on the Emotive setup - lines ordered, but troubleshooting some weird warnings with the car as it sits. Hopefully mounted up after...

Following up in thread since you asked separately! This seems reasonable to me.

Edit: Do not listen to this advice. Bushings are bonded to the bar. I don't see the bushings sold separately in EPC so seems like Tesla sells with the bar as well. IIRC LR AWD has the thicker 19.6mm unit. If it is indeed the bushings you might be able to get polyurethane replacements from...

@yjypm I am glad you brought this up. Some BBKs are massive for the sake of being massive. I will sit down and do the math myself as well. The third variable in static brake bias aside from piston area and rotor diameter is the coefficient of friction of the brake pad. That one is easier to...

I should perhaps re-state the disclaimer in each of the sections, but "compatible size" in this sense means it is within +/- 3% of factory diameter not that it will be a direct fit to the car or that the size even has a reasonable tire choice. FWIW, Mountain Pass Performance stuffed a 305/30R19...

1. To answer your original original question, I have some thoughts on why Tesla went with the 235. 265mm is 10.4" on a 9" wide wheel. Unsure if you have read this thread but there's some photos of 255s on the Uberturbines. 2. This may largely be dependent on the actual tire choice and your...

Absolutely an option that is being looked at inspired by some other setups in a previous thread. 👍 Have some parts being sent to a local powdercoating shop next week to sample their work.

I have found that spray polymers work really well to keep the hydrophobic properties of the ceramic "fresh". At the recommendation of my detailer I was using P&S Bead Maker for quite a while. It worked pretty well in terms of water beading, but I found that it attracted dust and sometimes...

Hope to have the Flex Z on a customer's Performance in the next couple of weeks. Sorry, no ride feedback yet as they just arrived and it sounds like you also want a longer-term review. I am pretty sure the reference is for a Japanese Domestic Model Performance model. I can capture this with...

18" APEX EC-7 I have to caveat this with the fact that this is on the ground since the shop car's front suspension is currently torn apart. You can see the studs are not 100% lined up, but my guess is there's going to be in the range of 15 to 20mm to the barrel. There's about 30mm from the...

It takes a village to raise a kit. This one is TMC's very own. @Lukez pioneered the 6-piston CTS-V DIY for the Model S. Then @jesse_le prototyped a rotor with GiroDisc for the Model 3 and Y. These full-floating slotted GiroDisc rotors for the Model 3 and Y come in at 370mm x 34mm. This mirrors...

I’ll be sure to weigh all stock Model 3 Performance components and get some brake line measurements. C7Z calipers arrive to the shop on Tuesday and I’ll bet GiroDisc ships soon. FYI: Summit Racing currently has the C7Z passenger caliper on clearance and comes out to about $8 more for the pair...

Those look well made. Does anyone have any hard data on rotor, caliper, or pad temps they're seeing on track - other than "percent of hot" provided by Track Mode?

I have been using TireRack and independent shops for decades. If you’re looking for the ultimate convenience, there are a few mobile installers on the TireRack installer roster (at least locally for me).

G-LOC Brakes was founded by racers for racers. When legendary driver Randy Pobst (of UPP Dark Helmet fame) ran this year's One Lap of America in a BMW X3 M Competition, he found himself with an emergency need for brake pads. While not exactly your typical performance car, G-LOC built and shipped...

For the cheap Amazon yellow passenger caliper, pull up the "Other Sellers" menu. Ironically the "other" seller is Amazon. This should bring up the $224 option which you can directly Add to Cart. It shows mid-August delivery for the cheapies. Also, tomorrow and Wednesday is "Prime Day". 6% cash...

One last rodeo on stock suspension and factory "who knows what it's set at" alignment for Holley High Voltage at Sonoma this past weekend. Now the building fun begins. Photo: Holley

Very late to the party, but G-LOC recommends R12 front and R10 rear. Finished up 5th track day with the R12/R10 combo over the weekend and have run it in the past on other vehicles as well. Love the modulation, but you already know that from using Carbotechs. :)

@santua only ONE more needed for the next order! Thanks for pushing this, Jesse and the fantastic research from @drpheta. Was chatting with @buckets0fun at the track over the weekend about this setup and cannot believe I missed this thread. I felt a spongy pedal on the way home and fairly sure...

Yes to hubcentric rings, assuming you do not have a Performance with the stepped hub lip. Your math to match the OEM backspacing is correct, but there is room on the inside for a higher offset and room outside for a slightly lower offset. Depending on tire size, ride height, alignment...

These are their spline drive "locks" or just order the singles. As stated by gearchruncher, you just need to find some M14x1.5.

Locking nuts are a deterrent, but a thief can bypass them in very little time. The idea is that they might not waste time on your locking nuts and just move to the next vehicle. Even rookie thieves can get past them. I once had two different sets of locks, but it became more of a hassle for...

I would avoid run-flats if you're looking for a softer ride. They accomplish running flat by having stiffer reinforced sidewalls. You can theoretically wait. Move the rears to the front though and rotate on time. The OEM tires will typically carry a price premium because people will stick to...

Dropping 13lbs from the top? Yes, please.

While this is bumped, Auto Werks Detailing in San Mateo has done more than a few of my cars if you are on this side of the Bay. Kevin does amazing work and has a steady flow of Teslas coming in and out of the shop.

18x9.5" APEX EC-7 +35 Flow Formed Fitting Some notes and pictures from when the new wheels went on the car. I have run APEX Wheels on my E90 M3 for many years and I am really happy that @APEXRaceParts is supporting the Model 3 platform "natively" with their new forged lines. The EC-7s here were...

You do not need to go to a TSportline or a Martian. At a basic level, the Model 3 requires 5x114.3 wheels drilled for M14 bolt holes. The centerbore should be larger than a 64.1mm centerbore for the "base" Model 3 and 70.1 or larger for the Performance due to its unique stepped hub - or the 64.1...

S1E2 - Thunderschleife Brakes On the last trip out to the track I resolved to switch out the stock brake pads and have a better charger strategy than RV outlets and distant Superchargers. I was able to find a local Model X owner who regularly rents out his CHAdeMo adapter which reduced the...

Did you have the car aligned when you had the tires replaced and how many miles ago was this? If it is lowered (sounds like it is) and your alignment settings are off (specifically toe) it will certainly increase the rate of tire wear. If you are looking to go back to all stock it isn't a...

S1E1 - Thunderhill Raceway Bypass - Willows, CA Fitting in a track day during the holiday season proved to be a challenge. Between family visits and school breaks it took me until the New Year to finally get the car on track. Luckily I was able to prepare a bit on the sim with the Tyrone...

Thanks and welcome to the forums! I am certainly not blazing any new ground here though. TMC is full of people having track fun with their Teslas. Our local Model 3 hot shoes are winning Time Trials/Time Attack events and then going out for double sessions in the late afternoon. Charging is...

Great lap! It's hard to tell from the in-car. How light does the car get over The Uphill?

Having mcbarnet007 blast past you in his street car down the front straight at Laguna Seca while you are in your fully caged V8 racecar certainly makes you a little envious. So last November I picked up a 2022 Model 3 Performance with the sole intent of turning it into a track weapon. This is a...

I went down there for the IMSA race weekend and no sign of any ground breaking. I wonder if they’ll try to take care of this in Q4 when the track is closed for the repave.

The County Board of Supes just approved a big budget plan for Laguna Seca. Not sure if any of this budget helps the superchargers, but I am happy to see the county is committed to the track Monterey County - File #: RES 22-086 I'll be down there this weekend and see if there's any evidence of...

Great thread and beautiful cage work. Looking forward to seeing this come together.

Still have an E90 M3. Have driven the F80 in anger at Thermal with BMW Performance School. Have taken the Model 3 Performance to the track twice now. The electric torque really helps you dig out of those turns and the low CG and location of the battery makes for a very balanced platform. The...

If you're getting "The Special Interest License Plate Internet Ordering System is currently unavailable." it's often because the personalized plate is already taken. The DMV site is terrible at error handling. These are all the restricted combinations and you cannot have the number 69 (NICE!)...
