It started in wanting something a little different for the Cav. I noticed that Wilwood makes 6 piston kits for similar sized compact cars ( Focus ST, Mini Cooper, Fiat 500 ) but nothing for us. I do have to take in consideration that the calipers that Wilwood are using were not available when the J-body kit was released. I contacted Wilwood to see what options we have in upgrading our kit to use larger 6 piston calipers and came up with 2 options. Hopefully, I can use all parts from Wilwood's catalog, then someone can duplicate this if they wanted too
Option # 1 – Dyno Pro 6 caliper
This option has a little less cost involved since you will be using everything from the existing kit, minus calipers, pads and mounting bracket. Since the Dyno Pro 6 is a lug mount ( kit comes with a radial mount ) it would require you to also make new caliper mounting brackets. Also this caliper is not as wide as the Dyno Pro 4, so there is some space savings if using a spacer to clear caliper
Calipers:
120-10134-RH

120-10135-LH
http://www.wilwood.com/Calipers/CaliperProd.aspx?itemno=120-10135
List of Pads:

Option # 2 - Forged Narrow Superlite 6
This option is a little more expensive all the way around, but it allows you to keep the radial mount. I will provide a complete parts list once I get my prototype kit done
Pic of the caliper
.81” vs 1.1” 12.2” rotor
Stock hat vs SRT-4 hat
The FNSL6 caliper is available in the rotor widths ( 1.1” and 1.25” ) not the .81 used in the stock Wilwood kit. ( Everything that I am showing is referencing the 1.1” rotor. ) The 1.1 in rotor is .29” wider than the stock kit and will not clear stock knuckle alone, so the offset of the hat needs change to compensate so the pics I am showing is with SRT-4 hat ( .77” vs .50” )
Stock knuckle
Well everything looks good from this angle
Then again…not so much from this one
The rotor is not centered in the caliper in the picture above. Looks like I will have to get another hat and take some material out of the knuckle so the rotor does not hit it

Any idea what the weight of those calipers is?
I may swap to the aluminum knuckles and all Wilwood parts.
um.. yes, please?
damn jason, doin work! love it. definitely following this...
RIP silver car. You will be missed.

Weight of the calipers is 4 lbs 10.8 oz
SRT-4 hat is 7oz lighter than the Cav hat @ 1lb 14.7oz

The Cav hat is thicker ( different offset of .77" ) on the left vs the SRT-4 hat ( .50" offset ) on the right

Will stock Z24 rims clear these?

I have thought about this. I was gonna call and ask them if they had a 9 pot caliper that would replace the 4 pot on just a direct bolt on...I guess this says the answer is no....

I highly doubt it Mike. I don't even have a stock wheel to try anymore

ryan slowzee got 13" brakes to clear on the stock Z rims...

hey very nice work jason. i will continue to follow your updates & progress on this project.
Why don't you mill the face of the bracket that way everything will come out away from the knuckle?
are those the right p/n for the calipers? i'm getting lug mount not radial mount when I go to wilwood's website
glad that my kit is lug mount then, its just a direct swap with the 120-10122

Yes, those are the right part numbers for option 1. If you are referring to the calipers pictured in this thread....I am using these (
http://www.wilwood.com/Calipers/CaliperProd.aspx?itemno=120-12002-BK ) which are radial mount but cannot be used with the thinner rotors. I did not provide the part numbers yet because I have not confirmed fitment

yea the 5.98" radial mount is what is used with the run of the mill wilwood setup for the jbody
just wondering I must have missed the lug mount part =X
yea..
reading> me
carry on I'll be quiet now lol
I'm watching this intently. Good show.

That is what I plan to do. I am looking for a local machine shop to mill the bracket for me.

Well, while I am updating threads I might as well do this one
So where I left off a few years ago, I had a Wilwood radial mount machined to the right offset
Well unforeseen by me, once the radial mount was machined the caliper no longer sat on the mount. It was not tall enough
I emailed TCE Performance and they built a custom Wilwood brake kit to my specs. 13.1 x 1.1" rotor, with 6 piston calipers ( with the same piston area as the 4 piston on the Wilwood kit )
I needed a small spacer to bolt up my 17" wheels
