hi all: just got my car back for service and had dealer install the gt3 brake master cylinder.........this 1 upgrade makes a big difference in pedal feel......instead of "mush" pedal is now really firm and solid....i would recommend this to anyone that does not like the brake pedal......

+1. Gt3 brake booster and master cylinder definitely helps pedal feel.

+1, it is a must for tracking it your car

Interesting, I was just told the dealership couldn't install the gt3 master cylinder as it is not a Porsche-approved upgrade.

Each dealer is different in what they are comfortable doing

The GT3 master cylinder is actually two steps up from the standard master cylinder provided in the 987 ( including Spyder and Cayman R) One step up would be the PCCB master cylinder which is also the standard master cylinder offered in the Carrera S. Since PCCB's were offered in the 987 there should not be any problem with a dealer installing that master cylinder in your 987 and you will notice a firmer pedal.

My dealer said that too but when I queried it with them they said they had never done one so didn't know if it would work, and that if I knew it would work (i.e knew of someone who had done it) they would be happy to do it.

IMHO it should be a standard fitment on 987.2's and certainly the Cayman R

You had an LA-area dealer install a non-approved Porsche part you bought elsewhere? Please do share which dealer is so accommodating...

I just had 997gt3 master cylinder installed in my '11 Boxster S by my independent P-car raceshop. I will drive the car in 2 weeks and give a report. (I'm out of town now.)

I think the dealer relationship happens on a case by case basis.

I find Rusnak Pasadena excellent and very accomodating.

My god. I couldn't drive the cayman with the stock MC. The brake pedal would slowly go the floor at red lights. On track, the car was undriveable, with absolutely no brake pedal feel. Gt3 MC ought to be standard equipment. What were these factory engineer guys thinking putting an obviously defective MC in all the cars? Pretty shameful by my way of thinking.

The GT3 MC 'army' is finally growing. Redemption. My sanity is confirmed... for now.

Undriveable? I had no issue lapping GT3/RS cars in my stock Spyder. I agree it's a little mushy, but not that dramatic.
