Brakes- Number of pistons ?

Hey Dirty- I will see if our locl Barns & Nobile has this issue. I just suscribed but I won't receive that issue.

Tommy- "safety and convenience above maximum performance and cost. In other words, you'd rather not be buying and installing expensive light-weight rotors on a regular basis".

Exactly.

Jason- looks very tight. What do you mean by, "IMO, for the money, there are brake packages than the the SSBC deal".

You mean like lower cost of other company's ?

When I speak with SSBC again, I'll let him know your rotor size and 6 caliper.

Thanks for the photo.

Willwood suggests a specific number of psi at the masters to have correct braking.When first setting up our car we discovered the rods off the brake lever to the masters was too low no way could we reach the pressure they suggested.Moving the rods closer to the pivot pin cured that and with the right pad compound the car will now stand on it's nose.
Be very honest about how you plan to use the car the most when ordering pads.

I've got the 12.19" 4 piston Wilwoods on the front of my Lone Star and the 1" or 3/4" MCs just didn't stop the car adequately. I ended up with the 5/8" MC. It stops like it should now and the additional pedal travel was minimal. I installed the 3/4" MC in the rear for it's Exploder 11" rear discs/calipers. Adjusting the balance beam got everything working well together.

Sorry! Better brake packages for the money. I have been a Wilwood fan, employee and now supporter for over 20 years (my stock car days).
So they are always my first choice. Mainly because of the price point, they offer high end performance at a lower cost. Replacement parts are far less expensive. Brembo, AP, Bear, etc. all make a gresat part, they are just more expensive.
I have a little experience with the SSBC line (the sliding calipers) and it wasnt great. so i carry a little bias.
However if SSBC is taking care of you, no reason not to try them out.

How do you find out the psi ?

Jason- We run Wilwood on the sprint car (one brake on front, one rear) for 12 years now with no issues, so i know their a very good product. SSBC are also good quality and like you said, their taking good care of me. If I were setting the car up as a dedicated race car, there's other choices as well.

Do you still work for them or retired ?

Take your time when planning your brake upgrade (a lot of factors to consider).

Here are few key points (no brake booster).

What is your pedal ratio.
Do u have enough fluid volume from your master cylinders to supply you Calipers??? Try to use smallest master you can that will supply enough volume for the calipers. Not enough volume = NO BRAKES
Use the largest rotar u can (u will gain mechanical advantage)
Buy a 2 piece rotors ( less likely to warp or crack also helps to keeps the heat away from bearings)



This is how u find pressure.

P = pedal ratio
L = Leg pressure in pounds
A = area of you master cylinder
F = output pressure of your master cylinder

P X L /A = F
example 6.0 pedal ratio, 100LBS pressure, 7/8 master

6.0 x 100/ .6010 =998 Now divide by 2 (2 master cylinders) = 499
pounds of pressure applied (based on 50/50 balance bar)

Good luck
