I've had the car lowered and can feel the front brakes working a little too hard, my IR thermometer shows that too. Is there anyway of increasing the bias for the rear?

If its been lowered at the rear then the rear brakes should actually be working harder than usual.

I would imagine they work harder when lowered too as the bias valve would effectivly thing there is more weight at the rear. I'm assuming that's how the bias valve works.

If it has a compensator, you can change the length of the rod.

As Smegal says, the length of the rod can be changed if you have the compensator...

However, if the car is a Phase 3 then the rear bias is controlled by the EBD in the ABS pump, and there is no compensator present. Wink

The abs kicks in too quickly and I feel as though the back brakes have a lot more to offer!

Running 215/45/16 Falken Ze192's 33PSI(F) 31PSI® I've driven a fair few 306's most of the braking can be felt on the front but on this car, it's excessive for sure. Probably crap calipers, as mentioned, I'll wait for the new discs and pads to bed in and take it from there.
