It's still a bit surprising that there are people out there who are willing to devote time and money to develop new products for these cars.

Now 928 owners have another product from which to choose if they want to upgrade their brakes.

Thanks Carl!

Ditto.
Thanks for the people that are still dedicate their lives on making goodies for the 928.
Thank you, Carl and Constantine.

Very Good brakes in their day. Going from memory (could be wrong) 60 - 0 stopping distance was 130ft for a mid/late 80's 928. The same 60 - 0 stopping distance for today's top cars is 100ft.

That extra 30ft could make a huge difference in an emergency. I have been looking at the stoptech and brembo sites for a while now as one of the upgrades I want. There was supposed to be a partnership that brembo was in with another company to make Ceramic brakes more widely available for the street. Brakes were the major difference when I drove the stradale.


Greg (from Aus) has had these (from an F50) on one of his cars. I think this is a great product.

I figured there were two 928 owners that would be interested in these brakes:

1) the serious racer

2) the owner who has spent good money on 18" or 19" aftermarket wheels, and is tired of the "little" rotors that are peaking out from behind them.

I was very impressed with the Brembo personnel and engineers, they really did their homework. I provided the cars for them to measure, the design criterium, and the funds to make the project move forward.

First, I don't think bigger brake discs are going to effect 0-60 unless your current brakes don't have enough umph to lock your wheels up. The shorter stopping distances today's top cars are more a function of wider tires. Bigger brake discs are for dissipating more heat from the increased heating due to lap after lap of threshold braking.

Second, got rear brakes with the lighter 2 piece hat/rotor to match?

Wider tires, better tire construction, softer rubber, improved suspension, and vastly better ABS systems have much to do with improved 60-0 times. One of the exercises we do at our POC Performance Driving School is having students get up to 60 MPH or so and brake HARD...very HARD. For most it is total amazement at how quickly the car will stop. Few people on the street practice hard braking.....keeps them from being "panic stops".

This has nothing to do with the brake hardware.

You can be deep into ABS, and adding larger hardware wont stop any faster.

When they tested the 928 back in the day, those 130 foot measurements were done on skinny 16 inch wheels/tires too.

I'm in the 2nd group

A local 928 track car has front S4 calipers on the back - might be an idea for a second stage to this kit. Move the old front calipers to the rear.

People forget about this aspect of new products when looking the price over.

Considering the low volume of 928's compared to other mass produced cars with similar kits on the market. This price is a steal.

The 60-0 braking is the first exercise in the Driver Tech school I teach twice a year at the local PCA. It is amazing even then the drivers that have something against stomping the brakes as hard as they can.

Why would I wanna look slower?

But they also function as wheel spacers......

The GT2 also recorded a braking distance from 60 to 0 mph of 98 feet (30 m)-- Its ceramic brake discs have a diameter of 380 mm at the front and 350 mm at the back – for excellent braking power.

Guys, I agree that wider tires should help with braking (and also cornering), but if your brakes have enough ooomph to lock up 7" wide wheels they can probably lock up 10"'s.


We talked about this in the cross-drilled vs non-drilled thread. BRAKING is ALL about heat dissipation PERIOD! You are converting mechanical energy to heat energy. It is that simple. That's why F1 rotors glow orange approaching turns and then just as fast stop glowing - Speed was turned into heat. A larger rotor has more surface to give off the heat and cross drilled helps too.

When you lock up the heat is given off by the tires melting off rubber, but you lose control. All in all BIGGER disks stop you faster and carbon will stop even slightly better because they throw off heat better.
