They offer a race pad (P3) that they developed only for the E30. I ran them last year. The best pad I ever had on my car. 2nd best is porterfield. Both pads will go the distance and both have very little wear on the rotors. The P3 stops a little better.
I know, thats why I gave you a link to their contact page. They also have a sponorship program available. Send them an email, they'll reply within a day.
