but is't that true for life in general...i just take everything with a grain of salt (whatever that means:p)

 

I could've sworn we talked about lightweight rotors a long time ago. Oh those were the days. Now I can't mouth off since I forgot everything I wrote here this summer, and I didn't learn anything I can use last semester.

 

ah light weight rotors...won't sell in america...liek 70% of american's are overweight...so why woudl they want a constant reminder oh how far they've fallen by getting lighter rotors:p


(hehe how was that shelleye_man_06 i used "lightweight rotors" twice in that post...well three times counting this question?)

 

Steel?

What about higher grade steel, Titanium, ceramic coating, etc...?

What is the highest revving rotary ever?

 

The reason the Supra and Skyline can take such abuse is because they have iron blocks.

The old 1.3L 13b-REW 2-Rotor weighed more than an LS1 5.7L V8 (we got good balance though cuz it was mounted low and rearward) - anyways

The new Renesis has taken 19lbs of boost on stock internals - if you were to replace these with aluminum bits you'd save weight, but you'd lose a lot of durability.

Its the same argument I have time and again, especially with the people in the wheels/tires forum - do a cost benefit analysis - sure you can lighten the rotors and get a decent gain out, but for the same price you can keep the strong iron internals and boost the **** out of the engine, and you'll make WAY more power (my argument with the wheels/tires guys is to buy a set of rims that weigh as much as stock and use the savings for go-fast bits that will more result in a far faster car than if that money were spent on super-expensive lightweight rims).
