Hi All,
I'm Rafi, and I run RR-racing.
Hopefully you've heard of me, I've servicing the Probe/MX6 community for 7 years.
About 6 years ago, I approached Fidanza and paid for the first production run of flywheels (just go to Probetalk and you can probably locate the very first BB run that I sold out of 6 years ago!). Back then I had a hard time convincing everyone that 9lbs was not too light for a flywheel! To make a long story short, I think it is safe to say that I was the one who put Fidanza on the map in the Probe/Mx6 community.
Very Recently, I switched to a new brand of flywheels made by Aasco Motorsports. Here are the details, as some of the information posted here is not accurate. I made the switch, because I honestly believe I am now selling an even BETTER product:
(1) Aasco Motorsports is well know for the line of Porsche flywheels, just ask anyone who deals in the Porsche marketplace.
(2) For other car lines, Aasco Motorsports manufactures flywheels for others, such as some clutch manufacturers, etc (I am not allowed to publically mention the names).
(3) Mazdaspeed aluminum flywheels were used by the Speed World Challenge Protege's and 6's are made by Aasco Motorsports, not Fidanza.
(4) Aasco flywheels are made in California, Fidanza is outsourcing much of their products to China to save money.
(5) I have personally measured runout on the Aasco flywheels, and it is about 40% better then Fidanza.
(6) Aasco flywheels officially weight 9.2lbs, not 11lbs.
(7) Aasco flywheels use a much more expensive to produce friction surface. Fidanza just bolts in a rolled steel plate, Aasco heat treats their plate and hardens it to make it more homogenious. This significantly reduces chances of chatter, particularly if you use "puck" style clutches.
(8) Regarding someone's comment that Fidanza has more bolts holding the friction kit then Fidanza. More is not always better. When we first came out with the Fidanza flywheels, they had 18 bolts, now they have 16. Fidanza reduced it for a good reason (actually due to warpage issues). Also, there is another issue, since the bolt notches are inset, technically speaking they accellerate wear of the disk (just as drilled/slotted rotors accellerate wear of the brake pad). Provided that the flywheel is well tested and friction surface is durable, you typically want to put as few notches in it as you can.
(8) My appologies to the buyer for not updating the website, i first had to sell all my fidanza stock.
(9) Since I just started selling Aasco Motorsports flywheels, I am giving my word that if you are not happy with the quality of the flywheel, or it isn't better then Fidanza, i will gladly refund the money. I've been around this community for longer then most, and I believe my reputation as a probe/mx6 vendor is second to none, so take it for what its worth.

I'm going to think about it for a day or so...
