I figure some here will have more info on this, but Wilwood is advertising it has a big brake available for 914-4s. Just in case anyone would be interested. I haven’t even looked it up yet, but seen the ad in Excellence.

I had BMW front calipers and the front brakes were doing 90% of the braking. The rear pads were hardly worn while the front pads were shot. I switched back to stock front calipers with Porterfield R4-S pads and pad wear is even all around. Greg Amy uses BMW calipers up front, but installed a brake proportion valve with heavy bias towards the rear for even braking. That is the exact opposite to what I would have believed would happen! With a 3/4" master and the BMW caliper the bias should move rearward anyways. I HATE the original pressure regulator. In stock form it does not even see the front circuit and is merely an accumulator that starts to fill beyond an adjustable limit. The stock pressure for actuation is 525 psi from what I remember. It just "snubs" the pressure at 525... For a stock car that's fine but I'm betting both you and Greg Amy are using non/stock tires and that threshold needs to be adjusted. I'll be interested in how the 75 narrow body brakes work when I am finished. |
