Hi, i have an old gc8 v3 Sti- i have standard 4 pot Calipers in front and 1 pot at back with hawk pads- these as getting a bit rusty and need to change (371.1bhp Steve Simpson) - i am removing the master cylinder anyway for Left hook conversion, I was considering...

remove the original bias valve for 50/50 braking,

Scrap Servo,
Replace with a shinny brake bias box,
Delete abs
Fit Willwood 6 pots at front

Keep the standard servo and go with Brembos of a 2001+ car, D2's etc?

My wife still drives the car now while i like an ultimate race car would this make it difficult for her? Is the pedal completely wooden? Any experience?
Cheers!

I can highly recommend removing the brake bias valve. Mine has been done three years this autumn and it feels far more stable and planted on heavy braking.

Super! Thank you that is as i read. I have Just been out and striped them- the cas has been in storage for a year and the rear calipers are seized too rusty to risk so thinking not to replace old with old... i think Mrs Santa will be good to me this year

Do you still have abs with the bias valve removed?

To answer your second question first, yes.

If the car is off the road and the calipers are of a decent type, why not send them to Ian at Godspeed for refurbishment? He is quick and decent price.

Or loook for an upgrade: mine now runs STi 2-pots via Ian's fitting kit.

How many of this bias valve is fitted to the Suby ? Basically what is involve in removing this valve.

Didn't do the removal myself, but AFAICS, simply unscrew the two pairs of pipes entering the valve, remove the valve body and link the two pairs of pipes to one another.
(NOT link each pair to each other, link the one going in on the left to the one coming out on the left etc).

Then bleed the system.

I can post a pic of it done if that helps?

Yes, please if you can post a picture.
Many thanks.
