wilwood or pbr brakes

[ponchopwr70]

I'm getting closer to buying brakes and have two routes I can go. My first set-up is wilwood 13" 6-piston fronts with sc+c stage 2 plus, 12" wilwood 4-piston rears and a 7/8 wilwood master. My second option is C5 front with afx spindles and 12" rear with 1 piston pbr with 15/16 master. (proberly would go with touring classics set up.) I will need to run spacers on the c5 system ( any ideas on a good spacer for tt2's or should I make my own?) The price is a little cheaper for c5-afx set up (couple-hundered). I need to run manual brakes. I'm not sure which system is the best one to go with in regards to, stopping power, pedal effort, weight difference, and relibility. The wilwoods look better in my opinion but the c5 look fine too. Any opinions or experience on these systems? Thanks in advance.

AFX+Wilwood???

My wallet isn't big enough for that. I have too many other things to get.

C5 PBR all the way.

Frank, check out http://www.skulte.com for wheel spacers. You don't want to run a wheel spacer more than 1/2", above that you'll want an adapter that bolts to the hub/axle, and then the wheel bolts to the adapter.

Not to steal your post, but I'm at the same crossroads. The Wilwoods are unfortunately out of my budget, but I can get the C6 Z06 kit with everything (hubs, brackets, pads, etc.) shipped for less than $2K. It'll make it near impossible to run TTII's so the $1500 I'm saving over Wilwoods might go straight towards rims instead. I can do the C5 conversion for under $1500, but is the C5 caliper with a good pad and 14" rotors up front (kore3 hybrid kit) and 13" rotors out back going to be sufficient for a 4000 lb full size wagon?

Thanks,
Eric

AFX with the C5 PBR/ Touring Classics!! Besides the fact that you won't have to shell out big bucks for the Wilwood set-up ( you'll never notice a difference in performance, unless you're building a track car) With the ATS AFX spindles, you get all the added benifits of improved handling with a great performance brake system!! I have that set-up on my 68 Camaro. Plus I have the added bonus of living here in Vegas, so when I was done transferring a totally restored car into a Pro Touring car, I had the priveledge of having Tyler and Russ @ ATS do my alignment and install my Global West sub-frame connectors!! All I can say is " Get in, Sit down and Hang on!!!" The difference with the spindles, is amazing!! You won't regret it. ATS is a dealer for Touring Classics brake kits also. One stop shopping

I have the AFX spindles with Wilwood 13" 6 piston brakes. I also am running the Wilwood 4 piston rear brakes.
Here are some things to consider that I ran into - A larger caliber like the 6 piston Wilwood or Baer brakes on the C5 AFX spindle requires a wheel that has enough clearance between the caliber and spoke of the wheel. Also with this type of set up a 18" wheel is needed for clearance. I had plans to run a TTII or similar wheel but cannot because of the spoke clearance. Currently I am having Budnik build a set of wheels to fit this application.
Looks killer but was not expecting the additional cost to make all this work together. I chose to run Wilwood because it gave me the extra clearance I needed in the rear due to the internal E-Brake. So to keep all matching I used Wilwood up front. If I didn't have the clearance issues in the rear I would have probable went with the 13" C5 conversion brakes with AFX spindles.

Thank you all for your input. I've made up my mind to go with the C5 caliper (not C6 Z06 or Wilwood). I'm buying a set of the tall Caprice/B-Body spindles that have been modified to accept the C5/C6 caliper brackets... it's going to require some fab work on the upper arm since nobody has anything for the 58-64 full size yet, but if all goes well I'll spend the money on the AFX spindles later. Is it safe to assume that the hubs I buy for a tall spindle (from Kore3) will work on the AFX spindle too?

Thanks guys. You rock.

The ATS AFX spindle uses a one piece sealed C5 front hub/ bearing assembly. That bolts into the spindle with three bolts. Gm factory part.

The Wilwood 6 piston, 13" front set up WILL clear "most" 17" wheels. Just went through this on a project in the shop with 6 piston, 13" and 17" wheels. Some will not, but most even shelf 17s actually will clear. TT2s come to mind. Spoke clearance is not typically a problem either with Wilwood unless offset has to be real funky for a particular car. With our beloved Camaros offset, spoke clearance is rarely a issue.

Well another set of wheels isn't an option. So does anyone have experiance with the c5 set-up as manuals? KMD your set-up looks nice.

Ponchopwr70,
The 17" Torq Thust wheel will fit the Wilwood 13" 6 piston brakes but only by less than an 1/8 inch. It is just to close for me, so I believe the 18" is a better choice.
The problem of the spokes interfering is because the caliber protrusion past the hub. This is mainly due to the application of C5 Wilwood brake. If you ran a different Wilwood setup other than C5 you might have better luck with the caliber protrusion. I did put the TTII on my car but had to use 1 1/2" spacer to gain clearance. I can't really tell you what the clearance will be with the C5 conversion brakes but I would have to believe it would be better.
I am happy with my set up now, but boy did it get expensive quick.

KMD what size master do you have with your wilwoods and how do your brakes feel? How do you like the afx spindles? To stay with the torq thrust I can either get wilwoods for stock spindle and use tall balljoints or go with afx and factory c5 brakes. I guess it depends on what I want more, to have afx spindles or to have wilwood brakes. I don't think I will notice a diffence with either set-up because they both accomplish the same thing. Sorry if I'm asking to many questions or being repetitive

I don't have the car running yet but getting close. I have a dual power master cylinder (1" bore). I will know more on how all works together once I get it running.
The AFX spindles are very nice, you will not be disappointed with the craftsmanship. I believe the C5 brakes are a good way to go also. They look good, perform well and cost alot less. I had some clearance issues with my rear brakes that I had to run the Wilwood set up with the internal E-brake. So I thought it made more since to run Wilwood in the front aswell.
I really like all the advantages that the AFX spindle offers. Improved suspension geometry and improved bump-steer for a A-body car.
I believe that the spindle offers much more advantages than the upgrade from C5 brakes to Wilwood brakes. But that is just my opinion. -Kenneth

i think i and martz chassis would say wilwood
