Willwood caliper rebuild?

[mike finch]

Can anyone suggest the right person to rebuild Willwood calipers? The car is a 2007 Stohr F1000.

Also looking for a skilled person we can pay to work on the car in Austin Texas.

Mike,
They are so cheap, you should just buy new ones.
I recall the front calipers were $150 each at Summit.

Mike, I concur with Ivinsea. Your better off getting new calipers. I did just the same thing when I built my 2007 Stohr / 2011 BRD car.

Are you using .375" solid or .810" vented rotors? Or did you get the split package with solids on the rear and vented on the fronts?

I'm not a Stohr owner but as a Wilwood dealer I can tell you that replacing them is a better option. Depending on how old these calipers are there have been some minor improvements in this model since 2007.

It is the split package with vented front, solid rear.

Thanks for the advice.

My intention now is to buy new. Had a quick look at a front caliper trying to determine a part number but couldn't see one??

Mike, since Gary is a Wilwood Dealer ask him.

I've got p/n 120-9705 for the Rear which is a 4 piston 1.375" (piston size) using a 3/8" thick rotor. For fronts if you've got the .81" or .75" thick vented rotors you'd use p/n 120-5082 or 120-9693-SI.

Most of us guys are using .375 or .380" thick solid rotors on all 4's (lighter). Don't know if your opting to change out rotors or not, but if your changing calipers... do yourself a favor and check your rotors for wear especially at the bobbin mounting holes for egg shaped dimensions. Mine were bad, hence why I changed everything on my braking system... Rotors, Calipers, pads, master cylinders, line sets etc.

As far as I'm concerned.... if you go fast you'd better be able to stop it! A compromised or semi-par braking system is not an option! This is one area you don't want to skimp on.

Oh, on another note, I've added you to our National 'FB' drivers roster also.
