I have two types of Wilwood Brake pads
Part No.150-9416K and Part No.150-8854K.
Anyone know which one is the BP10 and BP20.

Thanks

 

the 150-9416K are definitely the BP-20s....greg

 

BP10's are 150-8946K

 

gnatster: what pads are you running on the track? i switched to poly h's for my last track weekend. i like them a lot. i just hope they don't eat rotors too fast....

 

BP10- Street
BP20- Track

Need to bed in a new set of BP20's before I leave for RA, looks like a late night activity on the local roads.

 

i went through 3 sets of bp20's in three track weekends! that's the main reason i switched to the poly h's. (plus more tire grip available from the 225 hoosiers) it looks as if i'll be able to get at least two weekends from the new pads. i put on new rotors when i put on the new track pads. we'll see how they last. i've got Moroso next weekend, then i'll see you at road atlanta. looks as if we'll have a pretty good MINI turnout.

 

Thanks for the replies.
If the 150-9416K are the BP-20,s, what are the 150-8854K ?

thanks.

 

Running a google search on 150-8854K brings back that they are PolyMatrix B for both a Universal and certain Mustang applications.

PolyMatrix B are a great choice for most weekly racing applications on asphalt, and severe-duty use on dirt tracks. They feature an extremely versatile material with high friction values and low rotor abrasion over a broad temperature range. These pads require little warmup. Regardless of temperature, B compound pads offer smooth engagement with excellent modulation at low or high pedal pressures. Release is always quick and clean, giving you a better, more consistent feel.

 

I run the BP-10 on the street and the B pad for track days. I have 3 track days on the current set of B pads and will get 1 more day out of them.

I tried the BP-20 pads and wore out a set in only one track day. Also, they don't have the grip that the B pad has. The BP-10 is excellant on the street with very little dust or noise.

 

Found it....
looked on www.wilwood.com before did not see it, I suppose did not look properly.

Look under Caliper Model and then Superlite-4/6 Forged

150-8854K are BP-10
150-9416K are BP-20

Will be installing the BP-10 since I use it as daily driver and a track day now and again.
Thanks for the help.

 

I previously used Wilwood BP10 or BP20s on the track but found out that they couldn't deal with my braking and the Texas summer heat (ambient over 104). I have been using Performance Friction Carbon Metallic Race pads for over a year now. While they seem a bit pricey, they outlast any other pad I have used so, in the long run, they are about the same price as Wilwoods.
I never run the race pads on the street, just on the track. I still run BP20s on the street. Neither pad seems to cause excessive rotor wear.

 

UPDATES:

Please let me clear up what may be some confusion.

The smaller Wilwood kits are usually sporting the BP10/20 and B compound pads. The larger TCE/Wilwoods are the only kits which can offer these compounds and many others. The full line and explaination on them is here:
http://www.tceperformanceproducts.com/pads.html See the bottom of the page for the pads available for the DP (DynaPro) and the FSL (Forged SuperLite)

The 20's have proven to be a more potent high performance street pad worthy of light to moderate track duty. They however are not proving to be a good choice for hard track day use as they have a fast wear rate and when over heated (see the charts) do tend to drop off and go away quickly. For those uses you will be far better served by the B or maybe A compounds.

For the FSL customer the H pads are clearly the superior pad offered but in fact may be a bit more brake than many folks need for their use. Track junkies yes, HPDS events no. And none of these track pads should be considered streeetable.

Other pads such as PFCs are available from suppliers for the FSLs pretty regularly. Currently the DP caliper is short on many choices. A note that if you do run PFC pads they tend to put down a heavy transfer layer and alternate compounds may not be as effective immediately after fitting. Hawk also offers pads for the FSL however some compounds may require you modify the pad plate slighlty to remove the old style cotter pin hole and cope it for you larger bridge bolt.

 

todd: thanks for your input here. if anyone is running these brakes and haven't taken the time to talk to todd, do it. i had hoped that the BP-20's would serve as a dual purpose pad, but it didn't work out. no big deal as pads must be considered a disposable item for those who track their cars. if one is running track only wheels and r-comps, the time required to swap pads is minimal. the poly h's are sweet. many nervous porsche owners in front of me. i love my TCE bbk. greg

 

I hope this is the right thread...

Which aftermarket pads will fit on the wilwood brake kit???

 

CALL Raceshopper.com in Syracuse. Best prices on pads I've ever found. Plus all they do is brakes.

Depends on what calipers you have.

 

True. They are caliper dependent.

Here is the list of Wilwood pad options. You may find some from other suppliers however you'll need to know the pad plate number, not the kit it's on.

The smaller 11.75 and 12.2 are DP calipers, the larger 13" kits FSL.
