Well actually more rear brake and suspension Thought you guys would like this one. Entering turn two at Sebring I believe. No suspension upgrading before the next DE, but I will be getting more rear brake and some brake ducts. So, for those of you wondering what a good upgrade is, bias valve. OK well the file is too big.

I used to have a pic of my 944 up on 3 wheels coming through a slalom... Should have used it as a background before I lost it
Your back end looks kind of high

I have a bias valve on my 951, and it's so much better than without it. I don't know why they weren't standard.

Ive got a bias valve waiting to go in mine. And all new rotors. And Pagid Sports. SS Braided lines are already in

Does anyone know if there is a size difference between 86 951 master cyls and later ones? I read somewhere that 86s had a 17mm bore and later cars had 23 or so, thus a bit more stopping power...

5/33 928 valve here, puts a bit more to the rear effectively. You can also get adjustable valves...

How do i Identify the valve? My rear lock before fronts, but the PO said all he did was LBE and the strut brace. If i dont have a bias valve, I'll have to find out what the issue is. Could be that I just didnt do a good job bleeding the fronts after the SS line upgrade all around.

In anticipation of the next question...

Thanks, just checked, it says 5|18. Damn, that means I have more touble shooting to do!

I agree on the bias valve. One of the biggest bang for the buck upgrades or the track you can make.

Little bit bigger, crapy jpeg compression.

i might skip the ducting for now and do front springs and more torsion in the rear. Need to plan for that quickly though.

Wait, there is more than one bias valve? I thought if there was one installed, it was a 5/33, I didn't know there was a 5/18
Now I have to check mine...

Mikeaagesen

Can someone explain what this 5/33 and 5/18 means? I don't know what the numbers represent.

Eyal 951

Zero, 5/18 is the stock bias valve.

Mike,

It's the bar of pressure. The 5/33 means that 33 bar of pressure needs to be realised in the rear system till it relieves. Opposed to 18 bar. So, the 5/33 means that the rear brakes harder / longer over the 5/18 valve. Therfore more likely to lock up, but generally the car brakes "better". Can anyone confirm my nonsense?
