Light Weight Fly Wheel - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Is it possible to install a light weight fly wheel without changing out the clutch? Typically, I see people changing both at the same time, but is it possible to just install the lightened flywheel with the stock clutch? any benefits?

You can. I think most people do both because the clutch is bolted to the flywheel. So you might as well save the time and effort and do both.

well i'm just thinking about cost...the clutch itself is a pretty penny and depending on how i drive the stock clutch is probably going to last some time.

I agree, no need to swap out the clutch until it's worn out!

Thing is this, be careful on the weight of the flywheel. Smaller isn't always better. It WILL affect your driveability. It will be easier to stall, it will take more revs to do smaller tasks from a stop. Also remember, the lighter the flywheel, the faster your RPMs drop in between shifts as well.

To the best of my limited knowledge, only dodge was dumb enough to rivet their pressure plates to their flywheels for a "modular" clutch. It made changing them dead simple, but upgrades were a bitch and so was the price. I watched a guy change the clutch in a race preped neon (read nothing in the way that wasn't 100% required) in 40 minutes, including the road test, so there's certainly something to be said for it.

Op, just make sure you bed the disk to the flywheel much the same as you would new brakes.

I've driven with a lightened flywheel and loved it...but i do agree if you're not quick on the shifts, it'll get pretty jerky.

Any lightened fly wheels for sale?! PM?

Right, it just depends on the weight of the flywheel. Not all are bad.

Currently there aren't any standalone flywheels on the market, however Clutchmasters is supplying their Clutch kits with steel flywheels. I can give you a deal on that if you're interested.

I saw this post when searching with google, though id just mention that TTV Racing Components manufacture lightweight steel flywheels for use with the OE or smaller race clutches. I have a pic of mine if anyone wants to see it.

You can use the stock clutch with a lightweight FW. This clutch feels pretty sporty compared to what you'd find in a typical commuter car so i don't personally feel an upgrade is necessary unless you're going FI. See my post in another thread about lightening the stock FW.

Yes lightening a cast flywheel might be ok, its old skool and i like that! but you have to rememeber cast flywheels are designed for OE spec, lightening it will weaken it. Maybe ok for normal road use but running the car hard on track days or with more than standard power etc its not ideal.
Properly designed good chrome moly flywheels are not expensive, have you seen the mess if a cast flywheel fails? its messy so for me its a not worth the risk.

I also think the stock clutch feels good

Saw this on eBay...anyone had any luck with this?

I have a flywheel right now and I'm planning on using the stock clutch. Should work but I will find out on Tuesday

Compare where the flywheel sits to your legs too... it wouldn't have to scatter far to be making a mess of your lower limbs!
