II Much update

[parsonsj]

Maybe use BP-20s for street/autocross use and swap to Hs for track days?

3300# makes sence. I don't know why I thought it would be lighter. Lately I've been seeing cases of too much tire for a given car. I'm not even talking about PT type cars but dedicated race cars. In many cases if a tire isn't in it's operating temp, the size is irrelevent. I have no reason to believe that's the case with IIMuch but it's got me interested. I'd like to hear an update when you can. Where is your pyrometer?!!! It's the key to victory. Regardless, it's great to hear you're out on track keeping it real.

That could work. Try and take some temps at your rotors if you can, that would determine if you need a BP10 or a 20. 20's start to work well over 500*, while the 10's have a fairly constant Cf over the temperature range. BP-10's Cf starts out higher than the 20's at cold temps, which makes them nice for big rotors on the street.

One thing to think about is how well a H pad will bed to a rotor that was previously used with a different pad. Might want to call Wilwood to find out.

I think calling Wilwood is a really good idea. I think an even better idea is to call Porterfield Brakes, at 949-548-4470. I did, and I came away impressed and completely satisfied. I had called a few other places (Hawk, etc) to find pads for a set of uncommon Alcon calipers I had. After several calls to brake shops that had never even heard of them, I tried Porterfield. A gal answered the phone, she was as knowledgable in her field as anyone I have ever talked to (I think her name is Wendy, wife/racer of Andy P?), she knew exactly what I had, and knew that the pad was a custom, made from another. I went with their R4S compound per her suggestion, with regard to the tracks, I run/street duty. They can undoubtedly help you too.

Thanks Mark! I'll do that.

Maybe I will too...

I use the R4 pads on my Lola. Porterfield is one of the few places that has pads for the Girling caliper I use.

I put temp paint on my front rotors, - it disappeared!

[Damn True]

How much fun would that Lola be with modern brakes?

[David Pozzi]

True, I could brake a TON harder!
I can brake pretty hard now, just not for more than a couple of laps. With the weight balance and traction I have, I could brake hard enough to throw you into the shoulder harness!
