OK guys I have come up with a new kit to convert to the later and much more powerful dual stage brake servo.
These provide a significant increase to the brake force available. You also then have access to a huge variety of cheap and readily available spare parts.
You can also opt to use an S4/RS4 S6/RS6 A8/R8 larger 27mm master cylinder which is ideal if you have big brakes with a larger than standard piston area.
The larger master cylinder will restore a short & firm pedal feel.
Currently this is only proven on LHD cars, or RHD with a reverse intake manifold - I am just waiting on a stock intake in order to check clearance & fitment. It will be tight fit however no issues are expected.
Included:
Servo adapter bracket machined from 6082 T6 & hard anodised to 40μm
Extended pedal clevis machined from 34CrNiMo6 / 4340 / EN24T & zinc di-chromate plated
Modified OEM servo fixing bolts
M12x1 SAE brake line fittings
Brake fluid reservoir connector & terminals
Fixings

Optional extras:
I have a few good used S4/RS4 S6/RS6 servos available complete with 27mm master cylinder - £125 plus shipping
Re-built single stage PAS pump (bolt-on fitment) - £150 plus shipping
