btw Tony. A 1.75 sec improvement is great first time out. What times are you doing to put this into context?

Why? Because the factory 951 ABS system is extremely slow in its activation with far too small of a pulse, occurring way too slowly, and is far to easy to activate.
In short, on a race track it's junk.

Is the S2 ABS the same system as the 951?
The rear banana arms would have to have the holes for the sensors. It would be easier to buy 87+ parts with the sensors in them.
I would like to know the part numbers of ABS pieces Tony used, We are going to install ABS to son's project 951, but at this point it would be easy to use Boxster parts instead of 944 S2 system we have.

It's very substantial.
The top super fact POC GT2 cars (highly prepared 996 cup cars/996GT3 cars with excellent drivers (quite a few professional)are turning from high 1:23's to an average of a mid 1:24's.

A 2-row (the pins on the connector) 986 pump.
Note: You will have to rearrange the brakes lines where they enter the stock pump so that they align with the correct respective ports.
Also you will have to know how to pinout the 986 wiring harness so you connect up your wheel sensors, as well as a abs light, and finally an aftermarket OBD2 female diagnostic plug so that you can take your car to someone that has the factory Porsche software and PCMCIA card setup to reset the ABS and troubleshoot it if necessary.

Sounds like an easy improvement for those of us with factory ABS. Personally, I haven't found the factory system completely worthless. I did do some tests originally with it disconnected, but although I was able to match my times with a bit of practise, I was never able to eliminate the occasional lockup and flat spotting race slicks is too expensive for me so I have continued to run with it.
This does sound like a real performance improvement though. What's the bet there is suddenly a shortage of 986 ABS pumps?
