Sorry, I have to vent a bit and post something to watch out for on WW, the info above it possibly not correct on the BP20 pads.
From their site

I talked to one race shop and one brake company and WW and they all said the BP20 is for a guy building a street rod, not to dirty, works well, etc...not a race pad at all but look what they say on the site
I have had many sets of brakes and WW always has done the job very well, low cost, great performance, they just seem to have a problem with listing some pads correctly.
I spent over $440 getting front and rear pads over nighted to me, Carbotechs, instead of the proper WW as in BP30 or maybe 40 for my particular build because it was to late to get WW on time and I thought I had the right pads until it was posted here how the BP20 melted on the track.
