OK that makes a little more sense but still a new one for me!

Are bias valves a no no for us? I know there are several different ones installed from the factory directly on the MS. Thoughts?

I do find that I need to address bias with different pads front to rear. I had significant rear lock up issues running Hawk Blues all around. Many guys in our region use Hawk Blue front, and HP+ in the rear. I now use DTC-60 pads in the front, and Blues in the rear - a similar bias F/R but more bite all around - less pedal pressure.

That is correct, less bite than all yellow and more than all blue pads. I can't remember where I picked that one up from but it helps with the bias and is less expensive than plumbing in a bias valve.
I'd like to try the Hawk pads next but not sure which ones. 60's and blues or blues and hp+

Bias valve are not legal. Split friction pads address the issue well.

No blow out, wore out. The blue wears faster than the yellow and has less bite. With all yellows in the rear, they lock up very easily. So I installed one blue pad and one yellow in each rear caliper to help with front to rear ballance. I can still lock up the rear but it's much harder to do.


This is good to know. I was about to put yellows in all around. Never thought of doing that.

Rears that lock up before fronts mean spins, or less than threshold braking. You want front to lock just before the rears do.

So looking at the parts books there are N/A cars with MCs that have the screw in bias valves so I would assume that it would be legal to go with that combo. Not sure it would help or not with the bias issues.

Looks like there are the following MCs:
23/19
19/19
23/23

I would assume 23/19 would be the way to go unbiased. A strait 19 or 23 with a bias valve might be better?

There might be more but that is what I have found. I dont know how many different bias valves there are.
