whats the difference
 

between this:
http://www.srmotorsports.com/protege.htm
(Mazda Protege, MP3, P5 Aluminum flywheel)

and this :
http://www.protegegarage.com/
(Unorthodox Racing Nine Pound Flywheel)

^^ found in the 2002 protege section

there is a 100$+difference...im guessing there is a weight difference, but what could be the difference?

nope, they are the same 9# flywheel. asked Ken about this and he said that sometimes people are given different pricing structures based on previous sales and other factors. As protegegarage gets a little more developed and larger I'm sure they'll have THE best pricing in the mazda-piston engine game.

would there be a quality difference?

nope. I think they are the same unit.

well, i know what i want for christmas! :-P
