Has anybody done this? If so I would really like to hear about it

Would that not be a little over kill?

But I know that Boxster brakes work so I assume any 996/987 type of caliper will work.

It has been done, but it is expensive. VCI sells a kit around 7-8K for the front and rear. Racers Edge offers a 14" Stop Tech Kit that is a little less. Good Luck!

Yes, talk to Pete95zhn. He did it on his former 951 (RIP)

Pete actually had GT2 brakes at the front and GT3 brakes at the rear.

You could easily get away with just doing the fronts. What about changing the m/c though? Not a whole lot of reason (apart from the fact that they look great) to go up in size without changing other components. Might possibly work less than stock.

over kill on the rear but a 951 at 150mph requires at least as much front braks as a GT3 at 150 mph the 951 may be lighter but has effecive 70/30 brake bias front to rear wear as a gt3 has almost 50 /50 due to rear engine . so GT3 brakes are made to stop half a GT3 and you are using them to stop 2/3rds of a 951

Isn't that a contradiction though? If you want more stopping power to the rear then wouldn't you do the rears as well? Anyway you can fit a bias valve I guess. I'm of the same opinion though. If you have a high powered 951 (eg 450whp and upwards) why shouldn't they have the same stopping power as a GT3? We are disadvantaged enough compared to them and their electronic wizardry, we weigh a similar amount, have greater torque and in this case hp, so why not? However their calipers are not connected up to our m/c so perhaps we need to address this aspect too.

Can't seem to connect to Racers Edge website? Who's VCI?

Anyone measured stopping distances in their 951s??

60 - 0 I measured 104 feet. Seemed too good to be true, but I measured 3 times...

No, but on the road my stopping is pretty good. On the track at say 130 mph to 50mph is more of a test repeatedly.

Vehicle craft inc, they have been around forever.

well if you want to upgrade the rear put your fronts back there. but the rears are about 95% the size of the front stopping as i said 30% of the car . simply get a pyrometer and piont it at the brake or even the wheel and see if the rears are getting hot I've worked out to a few ways to do the master cylinder on RHD cars
one is hydralic assist tandum master no real advantage other than real estate for inlets
but the other is balance bar with masters mounted vericly i gues next i need to go balace bare and twin hydralic assist masters vertical . whoo thats a mouthful

Stoptech while a decent kit is not in the same league as the Porsche/Brembo calipers.....and I actually have Stoptechs on one of my cars.

It also depends what generation GT3 brakes we are talking about. The early GT3/996tt calipers and rotors will bolt up on late 951's for a cool, if you shop around, $3000 (new)....the sixpot are more , especially the rotors, and need adapters for early cars. One would have to do a lot of re engineering to make them fit on the later 951's.

If I had the money at the moment, I'd do a full PFC kit front and rear.
