how do the Mitsubishi Eclipse Turbo AWD/Eagle Talon Turbo AWD not fit in the GS class philosophy of "Get Spanked by a Mini Cooper S?"Fastrack wrote:

o Comment: AWD cars do not fit with the current class philosophy of GS.
E: STX and STU: Brake rotors may be replaced with any rotor of equal or larger diameter made from a
ferrous or aluminum alloy. Calipers are unrestricted, but must mount to the original attachment
points. Drum brakes may be replaced with disk brakes of a diameter equal to or greater than the
inside diameter of the standard drum part. Brake backing plates (dust shields) may be modified the
minimum amount necessary to accommodate allowed alternate rotors and calipers.
Because even though the rear drums on Civics of your generation are small, the discs on the back of Civics aren't all that big. I wondered which was larger. I would expect an aftermarket kit to be bigger because most of the mouth-breather, street tuner Civic folks are lured by anything that says "bigger" "more" or is made of a billet when such engineering and machining is complete overkill.Steve Ekstrand wrote:Why Bob?
No comparisons are necessary. The allowance defines the min rotor size as the inside drum size. Which of course is smaller than any commercially available rear disc conversion.
This is a joke or a mistake right? Aluminum alloy brake rotors (if there is such a thing for automobiles) are legal but smaller diameter steel rotors are not?STX and STU: Brake rotors may be replaced with any rotor of equal or larger diameter made from a

Smart machinists everywhere are milling aluminum rear rotors for STS Civics, even as you read this...John Coffey wrote:This is a joke or a mistake right?

COOL! Stock pads rear, something with more bite up front. Or maybe swap to induce trailing throttle oversteer?Steve Ekstrand wrote:On the EF Honda's (4th gen):
Available rear drums were 7"
Available rear discs were 8.4"
Stoptech used to make aluminum rotors... This isn't a new rule, al. rotors are legal in STX and STU.John Coffey wrote:This is a joke or a mistake right?

I think this is to allow you to run a 2 piece rotor with an aluminum hat.John Coffey wrote:This is a joke or a mistake right?

That's what I figured; it allows the very common two-piece rotors with Ai hats.Aaron Goldsmith wrote:I think this is to allow you to run a 2 piece rotor with an aluminum hat.John Coffey wrote:This is a joke or a mistake right?

If by "some" applications you mean those where no brake pad actually touches the aluminum rotor then I would agree with you. Otherwise aluminum is a terrible material for brake rotors.Bob Beamesderfer wrote:
As for Ai rotors, I can see 70xx heat-treated rotors being useful in some racing applications.

So, you're saying that heat-treated, hard-alloy aluminum was mere folly on the part of one of the leading manufacturers of racing brake components?Marshall Grice wrote:If by "some" applications you mean those where no brake pad actually touches the aluminum rotor then I would agree with you.

the heat treating is useless. a couple brake heat cycles and the metal would likely be annealed. and 'hard' alloy aluminum is still soft compared to iron/steel and wears significantly faster. Combined with the poor fatigue properties, rapid strength loss with increased temperature, and lower heat capacity compared to iron/steel make it a poor choice for rotors. that doesn't mean you can't sell them...in fact you'd probably end up selling a lot of them due to needing to replace them continously.Bob Beamesderfer wrote:Jason Uyeda wrote:Stoptech used to make aluminum rotors...

Granted, but there are forms of motorsports in which the brakes are used very little. Take Speedway motorcycles, which don't even have a front brake. If you're looking to cut some weight from a portly H-D 750, then an aluminum rear brake that only has to last 20 laps of a quarter-mile oval is a good investment. However, I doubt Stoptech made product only for what is an anachronistic form of motorcycle racing.Marshall Grice wrote:the heat treating is useless. a couple brake heat cycles and the metal would likely be annealed. and 'hard' alloy aluminum is still soft compared to iron/steel and wears significantly faster.
