REAR Racing Pads?

[TonyV]

Just curisoty.... do you guys run racing pads/shoes in the rear brakes?
Wouldn't racing pads in the front over power the stock rears pads?
Thanks guys, sorry for all the questions. (rookie;) )

[Cheers!]

It depends on the coefficient of friction at different temps. I would assume the fronts get hot sooner than the rears do, as the rears also stay cooler than teh fronts

So if you were to run some hawk blues (which don't work well when cold) and run some hawk HP+ in the rear which work really really good when cold, the brake balance would be messed until you got it hot.

To me if I do not have a brake bias problem I would run the same compound front and rear

Maybe Bill can step up and expand on this.

The issue with us Solo 1 guys is that the rear brake pads are usually more time consuming to change than the front, so we simply use an agressive street pad for the rear, and leave them as is.

I jack up the car one side at a time, and change 2 wheels/2 pads at once. It might add 5 minutes/side when changing into my track things.

I run the same pad material in both fronts and rears, but I go through 2 sets of fronts for every set of rears. Some folks run an intermediate pad (or less agressive track pad) in the rears. I've done track in front and street in back, and the car was noticably less stable when braking.

i use race pads up front and good street pads in the rear, i find the rear does not do much of the braking and have had no issues with brake proportion being out of wack either

ressurecting this thread to see what anyone else is running...

Would race pads all around be best for a track only car?
I was thinking maybe some hawk black's ( HP plus?) or some 97 series performance friction's for the rear, to go with Hawk Blue's in the front? ...Rotor Wear is fairly important for me in the rear...

:confused:

Tony, I think it depends a lot on your car. As wgt transfers forward the fronts have to do much more of the braking than usual and the rears less. If you add in R compound tires there is even more wgt transfer meaning more braking for the fronts to be capable of. Also for my car the stock proportioning valve is slighly rear biased anyway so there is no need for good rear pads on my car.

This past weekend the brakes were working fine but there is virtually no wear on my cheap OE rear pads. Although my car is heavy enough to heat up HT-10 pads very quickly up front the rears never got all that hot so I see no reason for race pads out back.

After a bit of experience with track cars, as well as a fair number of discussions with some brake pad engineers, I find that unless you have very good weight distribution while braking, you will need to stagger your friction materials, from front to rear.

How much you need to stagger, and which compounds you will need to use will all depend on your use, your car, etc...

As a general rule, I would usually suggest that you stagger 1-2 levels of compound. So, for example, if you are using Hawk Blues in the front, a good match to the rear would be an HP+. On a very heavy car with a lot of weight transfer, you may need to stagger 2 compounds. On a stiff car with fairly even weight/torque distribution like a modified Subaru, or a Porsche, you may use Blues all the way around.

Of course, all this depends upon what you are using the car for. Blues should NEVER be used on the street or on a Solo 2.
