So then the same as the non upgraded brakes.4 piston front, single piston (floating) rear.

Same number of pistons, but not the same size.So then the same as the non upgraded brakes.
There is brake proportioning valve which sets the pressure ratio from front to rear.any further increase on the piston size would put too much bias towards the front.
Seems like it would depend on the wheel. Not sure what the minimum safe clearance is.
Well crap, guys. Looks like 18's aren't going to fit over Performance brakes. Somebody (Alighieri256) just recently posted in another forum that the rear clearance between the caliper and wheel is 0.955" (a quarter). 19's will fit, but no 18's. Interesting enough, the fronts have a bit more gap and might BARELY clear 18's. Crazy that it is the rear that are the problem.

Can you please clarify if the wheel size showing in the pictures with "quarter" clearance is a 18" or 19" wheel.
It is neither. My understanding is that would be the 20" wheel that comes as part of the Performance Upgrade Package that includes the upgraded rotors and calipers.
The performance brake package has 355*/335mm rotors (w/red calipers)
Unless you are certain that their piston sizes are indeed different, until further proof with a physical check*, I would think they should probably have the same piston sizes based on the fact that the rear rotor size and caliper are the same on both models, being now the performance model has an oversize rotor of 355mm (vs. std 320mm), any further increase on the piston size would put too much bias towards the front.
Model S front is a 4 pot caliper with 40/44mm pistons and is the same as:
Aston Martin DB9Another mid range popular motorsports cars with 4 pot calipers are:
Audi TTRS
CamaroSS (G5)
CTS-V (V1)
Mustang GT500
Viper (G3/4/5)
Brembo's GT40 (aftermarket)
EVO 8/9/10 & Subie STi both are 40/46mm
*Anyone here has done this?
Has somebody actually measured them to know that? (I have seen it reported anywhere officially yet.)
Front 355mm diameter is a published dimension by Tesla, although same in diameter as S but must be in different thickness due to different calipers.
The new STi has 6 piston front brakes.
My IS-F had 6 pistons calipers with 360mm rotors and 18" wheels fitted just fine.
Does any one know if model s brake hardware will bolt on model 3?
The HRE site states that the FF01's are not compatible with the Model 3. How did you get these on? They have no wheels with the 5x114.3 bolt pattern.HRE FlowForm FF01's FTW!
20x9.5 w/ 255/30/20 & 20x10.5 w/ 275/30/20. Email [email protected] for more info!

Will 18s fit over those? I am pretty sure not but always worth asking.Model 3 front OE 1pc rotor (320x25mm) weight (used @10,000 miles):
Track duty rotors (355x32mm) retrofit to model S caliper (compatible with model 3 hub/spindle) Rotor shown is still a model 3 rotor.
