Went to a DE this weekend, and to my surprise and embarassment, completely wore the front brake pads down to the metal. Of course no AutoZone, PepBoys, Advance Auto, etc., had Lotus brake pads, so I bought cheap Chevy pads, traced the outline, and with a hacksaw cut off the friction material and epoxied it to the denuded Lotus backing plates. Got me home 450 miles! I don't recommend any one do this except in an emergency brought on by stupidity, that is, not bringing spare brakes to a track event. I won't make that mistake again.
