I talked to Cindy Frei (Program manager for Prowler) today. She
said that the aluminum rotors are slated for the back only, while the
fronts get iron like everybody else. The front calipers are Minivan
pieces, the rear calipers are Neon fronts. She also said that most of
the advantage of the Prowler over the Viper is its weight advantage. The
Aluminum rotors effect braking very little.
I also talked to the former brake systems manager at Cadillac
this morning in the coffee room (He is now my manager) and he said that
they found very little difference in braking distances. They still
wanted to do it though because of mass reductions, but it was a $28.00/rotor
hit, above the price of iron rotors!! That's alot in OEM terms.
OTOH, I talked to Ned Ritchie last Friday, who reported using AL
rotors on a race car at Daytona, and after 24 hours, they looked good as
new! Who knows? I don't.
