Hey, will the resurfacing of the flywheel affect the balance in the engine? Will I need to run a counterweight even though only a small amount of the weight has been removed? I'm not turning my stock flywheel into a lightweight flywheel.

Thanks

No it will be just fine. Don't even worry about it!

Thanks a lot!


Second, does anyone have experience with a lightweight flywheel? I got my eyes on the ACT Streetlite and I would like people's opinion about a LF. My car is daily driven/weekend racer and I thought upgrading the flywheel would be a good idea. However I'm not willing to sacrifice the pleasure of driving over performance. I want to know if its streetable and if traffic/city/highway driving will be very different. Also, I need to mention that I have upgraded to a ACT heavy duty pressure plate.

Thanks!

There's been a lot of discussion on this already, so you may want to do search.

IMO you will like the lightweight flywheel. It is not any harder to launch than the stock flywheel .

you'll need to buy a counter weight from an automatic FD to fit a light flywheel

Surfacing a flywheel will not affect the balance because the material is removed evenly. This is also part of the reason that the balancing holes are on the back or outside of almost all flywheels.

I've never met a rotary owner that didn't enjoy a lightened flywheel. The engine will rev faster which get you to the good spot sooner

Nice, Thanks a lot for the replies guys! I think I'll upgrade!

You're certainly entitled to your opinion, but after 7 years of lightweight flywheels, I'm done. I'm in the process of putting a stock one in right now actually. It doesn't make your car faster. It makes it more prone to stalling on deceleration (there are workarounds) and it makes launches harder. Yes it free revs better but I think it just wears on you after a while.

Raymond, have you been running with a heavier clutch? I've found running with a heavy pressure plate or a puck-style clutch lessens driving enjoyment mainly.

I have been running a STOCK clutch on my car the whole time I've had it. When I put the new motor in about 4 years ago I put in a light flywheel. Love it. Car isn't hard to launch, drives fine. Cars I've driven with heavy clutches or puck clutches are the opposite, really hard to finesse a launch, etc.

My wife has driven my car with zero complaints or "this is hard" and she's typically the first to complain if anything is SLIGHTLY hard about sometime. Well, she does complain about the loud exhaust and bouncy suspension, but that's another thread .

Yes, I have been running a heavier clutch. Stock clutch is going to be easier to drive. I suspect there are not many FD's out there with stock clutch + lightweight flywheel. It's usually "I'm increasing power, I want a clutch that can hold more power, might as well change the flywheel too."

The idle issue (pop clutch in and it stalls) is going to depend on the weight of the flywheel and the actual clutch you are using. Clearly stock clutch + lightweight flywheel is going to minimize that issue.
