Vendor Street and Track Performance Pad options for Base and Performance Upgrade Brakes Now Available

[EVTuning]

We now have Performance and Track only Pads for Base and the upgraded performance brake caliper option. We also have two piece stock size replacement rotors. They shave on average 5-6lbs of unsprung weight per corner. Rings can be replaced separately when they wear out. Model 3 Brakes (Images are base pad shapes)

Are the rears for the Performance 3 ready to ship? They show unavailable on RB's site. PDM3PR-391

Not yet, few more weeks. Very strange design. It’s busy season for track brakes right now so trying to get it prioritized. Ordering now ensures you get in on the first batch. More orders means it’ll get more attention.

As a performance owner, I found the "now available (but not really yet)" disappointing. Hopefully that will be short-lived. :|

I understand. I am working on getting them to get the rears pads ready ASAP.

Ordered front and rear XT910s earlier, along with braided lines and a pressure bleeder. Have some Castrol SRF waiting to go in too. Hoping this will set me up well for my first HPDE track day with the P3D on 5/18. Fingers crossed for the rear pads to be here by then!

@EVTuning Have you actually mounted the RB rear rotor on P3? I preorder a set from RB directly back in January, which they finally shipped to me 2~3 weeks ago. Due to my schedule, I didn't get a chance to install them until couple days ago, sadly the rear rotors RB sent to me did not fit. I've since contacted RB about this and still waiting for them to come back to me with a resolution.

Just want to make sure rest of the Tesla P3 community can gain from my learning experience for being an early adaptor.

I had some issues with base brakes rear pads but those have since been resolved. Let me see what I can do to help your situation. They’re typically great with getting things sorted.

Any extra help would be appreciated.

Warren there is pretty good at sorting things out for me.

FYI, I just posted my installation of the Racing Brake 380mm BBK for P3. - P3 Brake Job

How badly will I wear through the XT910 compound for occasional track usage and mostly autocross?

Not really willing (at this time) to switch between that and the XT970 compound on a regular basis. Since XT970 seems like too much to use for daily driving, figured the XT910 is at least better than stock.

Will I also wear rotors faster?

 

[Lunares]

Also, any plans to offer XT960?

Eventually I’d like to see the full line. But funding this alone I have to prioritize where and what we have Racing Brake first. If we get enough traction with the other two compounds I can reinvest in a third option. This is all small batch production stuff for now.

I'd be willing to, since I have base model calipers and those pads are a lot easier to swap. Easily less than 10 minutes, probably closer to 5 min w/a little practice, total time added to the wheel swap I'll be doing anyway.

However I'm wondering about the implications of swapping pads vis-a-vis bedding. If I'm putting in the XT970 (front only, I assume) the first time I'm going to have to go through some sort of bed-in for them I think, to get them going. IIRC pads usually need to be heated to around operating temps once to get their surface, and the binding material in a thin layer below that, prepared for actual use.

But for sessions/days after that can I basically swap between the XT910 and XT970 on the same rotors and treat them as already bedded in, just swap and go?

Also, can I swap rotors underneath the XT910 and that's okay, too? For SCCA AX events I have to go back to stock rotors, because arbitrary Street Class rules and stuff.

Awesome! Racing Brake decided to make a P3 specific rear rotor. It will be 1mm thicker than stock and work with the stock caliper. The rear rotor kit will come with P3 specific XT910 pads.

More information on the RB 2-piece rotor replacement for P3, It will be 1mm thicker and with the patented convergent vane and center mount design to improve cooling. The CAD simulated weight is 13.5lb, stock P3 rotor weight is 14.18lb, so the projected saving is 0.68lbs per rear side. CAD rendering is missing the open slot.
I'm looking forward to having these complimenting the front RB system on my P3. FYI, standard 3 replacement rotor is already available.

New CAD renderings.

Why does @EVTuning say 6 lbs per rotor but yours says .6 lbs?

Why does @EVTuning say 6 lbs per rotor but yours says .6 lbs?

Because EVTuning/RB had the wrong weight for stock P3 rear rotor. I took my rotor measured it then provided the correct weight to RB this afternoon. You should see both EVTuning/RB update their web info in the next few days if not already.

Photo of stock P3 rotor on scale. 14lb 2.9oz or 14.18lb. You can do the rest of the math.

 

[beastmode13]

Weight saving from rotor is not a simple goal of just overall saving. The goal is to increase the thermal and cooling capacity of the rotor brake surface/area, aka ring, while remove weight from the hat section of the rotor. P3 stock rotors are Brembo 2-piece design with stamped steel hat that is only ~2.5mm thick and vented cast iron ring at 20mm thick is a good option from OEM on a mass market car. To achieve the stated goal, RB increase the thickness of the ring by 1mm which adds mass for thermal capacity. With there convergent vans, open slot and center mount design, these improve the cooling. To save weight the hat is made of aluminum which is standard hat material for most performance aftermarket and OEM rotors. The lightest rotor might not be the best brake performance option.

 

[beastmode13]

Updated rear P3 rotor from RB, reduced weight to est. 12.5lb. Stock P3 is 14.18, RB's new design will be ~1.68lb savings per rear side Guess who will be one of the first with these on a P3?
