Boxster S brakes on non-S

[steve_wilwerding]

I know that there are some old threads on this topic, but I'm just wondering if there is any new information.

Would like to put 986 Boxster S brakes on a '98 Boxster. I know the rear calipers/rotors don't fit, and I've seen that Brembo sells (or at least used to sell) "hybrid" rotors that fix the issue. Is that still the case?

My guess is that I can buy Boxster S calipers on the secondhand market a lot cheaper than I can buy the whole kit from Brembo, and if I could just get the rear rotors from them, it would cut down the cost.

Any other new options available? I would like to do all four calipers, rather than just doing front S brakes.

Brembo no longer has the hybrid kit (or parts for the rear) available.

It looks like Suncoast sells a kit to upgrade just the front brakes to S calipers/rotors - I'm wondering how much this throws off the brake balance (which is already biased quite a bit towards the front).

Anyone done just the fronts?

I had 2001 S big reds installed all the way around on my '99 Boxster. What you have to do, or have done, is the rear wheel bearing carriers have to be replaced with the S wheel bearing carriers. You will also have to replace the emergency brake mechanism to the S. When you replace the wheel bearing carriers the ABS light will come on because your axle is smaller than the S axle and the sensor will not sense rotation accurately so you will have to make a bracket that allows the sensor to be further in the carrier or install S axles. It can get expensive but I looked around and found a wrecking yard that sold me all four calipers, drilled slotted rotors, new pads, the carriers, emergency brake and a bracket for the sensor and installed it all for $1500. I've had the brakes on for about two years and the difference has been incredible especially on the track. If you can do the work yourself you should be in that price range.
