[DeTomaso] Proportioning Valve recommendations

[JDeRyke at aol.com]

I personally use a Kelsey-Hayes knob-adjust valve sold by Ford/SVO, also 
used by stock Corvettes for years, and sold thru some of the vendors. I have 
had poor luck with the lever actualted valves 'cause the variance between 
positions is too coarse. 
I also added two 1" OD gauges (0-1500 psi) in the front trunk to show me 
what pressures were actually going to the calipers. My pressures won't be of 
much help to others, though: I use Wilwood 4-piston Superlite 2s in front & 
aluminum Porsche 911-S two-piston front calipers in the rear. But the gauges 
are a nice tuning tool. FWIW- J Deryke
