a little background on the car: I have a n/a s5 and its pretty much stock. the car has a rb header, custom 2.5" piping to the borla cat back. i have a 4.30 rear end gear set too. i'm replacing the clutch and the flywheel. i was looking at the rb aluminum (12 lbs) and steel(17 lbs) flywheel. i wanted to know how many of you guys are running the aluminum flywheel and how streetable it is. i plan on throwing a spec stage 2+ kit in it and i just wanted to know if i'd be better off going with the lightweight steel flywheel rather than the aluminum one. and help and input would be greatly appreciated.

thanks,

izzy

 

to each his own from the 1000s of threads ive read unless u plan on going ***** to the wall stick with a 16lbs steel flywheel

 

thats what i read too, but i had read in the racing beat technical catalog that because i'm using a 4.30 rear end that i should be able to use the 12 lbs flywheel for street use. i was just wondering if there was any truth to it.

 

I've run both and I prefer the lightweight steel flywheel in a car that is as heavy as an FC and is only street driven.

 

thanks for the input. i'm leaning more towards the lightweight steel one, because i don't want my car to be a pain in the *** to drive daily.

 

What? FCs are as light as a car can get almost!!


And WTF is that **** about the car being hard to drive with a light flywheel?!

I have a Cusco 8lbs flywheel and its as easy as it was when it was stock. The difference is that the engine revs faster, period. It has nothing to do with a pressure plate.

Trust me, if it makes a difference, it only makes the car easier to downshift. Its a lot easier to adjust the engine to the right rpm. I bet that all that talk about a light weight flywheel making a car harder to drive comes from noobs who never owned one.

 

Where did I say anything about the car being hard to drive with a light flywheel? I said in a car as heavy as an FC I PREFER the lightweight steel on the street. An FC is heavy as hell compared to an RX-3 or an R100!

 

"And" is the word you missed in "And WTF..."

It starts another subject.

 

Yeah, I realized there were two subjects but since you only quoted my post, it looked like you were still talking to me. That's cool.
It's still a fact that as far as rotary cars go, the FC's are heavy.
The aluminum vs light steel flywheel debate is more of a personal preference.

 

So for someone who wants their car to be extremely responsive the aluminum one is the way to go? I know how it works but I have never driven a car with a lighter than stock flywheel. I like the rpms to rise really quickly so I'll probably go with the aluminum.

 

so from what i'm reading, the aluminum flywheel will be perfectly streetable? alright, well i'm ordering a flywheel tonight so i'll make a descision off of this info. if anybody else has some good input, by all means speak up.
