6 Piston Wilwood UPDATE!!

[sm105k]

Hey guys, sorry for the delay in response. COVID keeps me pretty tied up with the kids at home any any time we leave the house it's as a family so my testing is limited to solo trips to the grocery store haha.

I've had the kit installed for a little over a month now, and will be pulling it back off tomorrow evening to check the integrity of the adapter and to inspect all parts to ensure torque specs are correct for the material. Drawings and work instructions are ready for release, and I have worked with our suppliers to bring an entry level pricing for the first buy in amount, looking to be a minimum of 12 units.

Attached you'll see some testing that was done to compare the Wilwood setup to other options currently commercially available in the SHO community.

2013 SHO PP factory brakes with fairly new Ceramic pads - 2.75 seconds, 124.33'
Jordan Randle's 2013 SHO non-PP with Powerslot rotors and pads - 2.62 seconds, 116.65'
2013 SHO with Wilwood 6 piston rotors, R1Concepts slotted rotors and BP-20 pads - 2.57 seconds, 114.71'


I will say there are several variables in the testing, from pad material to incline between testing, but the Wilwoods were much smoother, less fade and steering shake, and did not take near as much pedal force to stop. I am hoping to test again in the coming days to see if I can improve the times with the Wilwoods and will report back.

Thanks for the info!

Yea, to really compare stopping power like you are, you need to have all 3 setups at the same track on the same day with the same tires...

Tires make a huge difference in stopping power as well and road/outside temps make a massive difference.

Ideally a track where you can really lay into them over and over would be best.

I disagree.  They need to be done on a public street at the same time with the same tires in the same conditions.  That would be the correct test.  A track is a prepped surface and can enhance the tests. I prefer real world conditions for a real world application.

I suggested a track as it’s the safest way to conduct these types of test. If there is a paved location where it can be done safely that more replicates real world testing, great.

But you still need the same tires, same day, etc etc... or the test for stopping distance isn’t valid...

Also, a stress test would be good too.. how fast does the stopping power deteriorate under repeated abuse such as hot lapping or going down a very windy mountain where you are on and off the brakes a lot...

Just sayin.

I agree.  The last statement is really profound.  With my Powerstop Brakes and pads I have one good stop from triple digits before my stopping power deteriorates rapidly.  Also in the mountains I have found the limit to my current set up as well.  It also wasn't pronounced as well.  One corner I had brakes, then next corner....incredible fade literally nothing.  I was lucky the corner wasn't a decreasing radius and after there was a good bit of run off. Took about 7 mins of normal driving to get things to somewhat normal.  I even have my shields removed.

Still hasn’t answered my question... based on the info provided...if this isn’t going to provide much additional stopping power for a 2013+ since it already has the bigger MBC....

Is there any benefit beyond the name? I can buy rotors and pads anywhere.
