MPP Front Rotors

[Msjulie]

I didn't know where to post this so it gets its own thread; finally installed the BBK (front rotors) on my previously Stealth Performance 3 (I wanted to wait till after Tesla corrected a minor alignment adjustment cause they were gonna do it for free)

Not having a lift is less than fun but not really difficult. Just a couple pics, I started pretty late in the day and after cleaning up and all, it was kinda dark out... Yes... I had my calipers painted because I wanted to...


Everything off, brake tied up with wire tires

old bits, garage is a mess - those parts now safely stowed out of the way

initial tighten, car still up in the air - 129 lb/ft torque still seems pretty high to me but that's what I found everyone saying ( full tighten didn't happen till car on the ground)

Weird flash effect at the rotor/caliper upper corner... there's nothing wrong there, it was just a weird phone camera flash thing

Drove a mile or 3 to bed things in (didn't yet put the MPP pads on, but I will after some time... doing my own baby comparo there)

I think the brakes feel stronger but it could be in my mind... there's no increase in pressure but there's a bit larger sweep so maybe there's that increase of brake torque to the radius increase? MPP folks will set me straight no doubt

I do like the look of them too..

cheers

@Msjulie,

Ooooooooooo....eye Candy! Love it. Could you snap a pic or two in daylight!? Maybe straight on and at a slight angle? Great job!

P.S. Jealous!!!

So they only provide the front ones? What about the rear brake?

 

[Msjulie]

I went back and forth about and for now just fronts for me.. they have rears of course though

Car needs a bath, then I can take some better overall shots. Driver's front for now..

"The formula you need is Torque = Force x distance... braking torque is equal to the retarding force provided by friction between the pads and rotor, multiplied by the radius of the contact point between the pad and rotor.

Reference www.physicsforums.com"

I do feel quicker brake response.. I just wanted to prove what I thought I recalled

Looks nice! I saw on their site that the rotor hat gets rid of the lip on the hub. Did you have any issues with fitting the wheels with the OEM offset since it moves everything a few millimeter outboard?

 

[Msjulie]

@FrunkingFast I didn't observe anything that concerned me, the rims are 'early' 19 EOM - before they tweaked them for performance winter use *i think*

I caved.. I ordered the rear ones as well and they've shipped so yippee! @MountainPass

I think you were referring to this, for the Performance cars w/OEM big brakes

"NOTE: The P3D is known to have an extremely thin rotor hat. Our rotor is approximately 4mm thicker than the OEM rotor, so this will move your wheel outwards by 4mm. Using this rotor also removes the issue of the hub “step” that is often an issue for aftermarket wheel fitment!"

My car is essentially the AWD w/software unlock (and maybe somebody tested the motors more ..)

Can't wait for you to install the rear rotors! Thanks for the photos!

Rotors are supposed to be lighter. Did you notice any improvement in range?

Not yet, no big trips. Once I had an Audi A4 that I put Audi A8 front rotors on and they were heavier and you could feel it.. I *think* I may feel a difference here but it's 4lbs a wheel so maybe not..

Rear rotors arrived today, hopefully a weekend install coming depending on how cold and stormer it ends up around here..

Nice! Now you're ready for the next Tesla Corsa

 

[Msjulie]

Car still filthy (rain everywhere )

But rear rotors on - don't forget to put the car in tow mode before you disconnect the parking brake power line.. not a biggie but a time waste when you forget

The MPP site has a picture compressing in the rear caliper piston with tried and true clamp and such but I happen to have real brake tools Either works of course..


My tools, there's only a zillion brands



Towing mode retracts the piston almost all the way needed, needs a tad more and to have piston lined up so the pip on the brake pad slide into the slot on the piston (yes the paint job didn't get the way back of the caliper but it works for me...



old vs new - reused the set screw on the new one fwiw



dirty car, cool rotors

Also put in 2 missing liner plastic pins... my car feels better just knowing I did that..

Did you weigh the difference?

 

[Msjulie]

From MPP site, fronts:

• Lightweight, 3.41lbs lighter each

Rear doesn't have as much detail

• Significant weight reduction from the factory rotors.

So no I didn't weigh them myself.. Carrying the boxes with old vs new, you can tell there is a difference but w/o MPP to confirm I couldn't say how much in back

I will update the website!

MPP Rear Rotor: 13.09lb

OEM Rear Rotor: 16.88lb

I will update the website!

Nice, can you add the diffs (on website) from OEM as well for rear rotors?

 

[Msjulie]

So it was cold (relatively speaking) in the south Bay area this am, just under 40F - so regen correspondingly absent... using the actual brakes was satisfying as I am more convinced the new rotors bring a more responsive braking action..

Carry on

How did you paint the calipers so well? Did you hand paint the white Tesla letters or found a sticker?
