Less weight, less inertia, slower off the go due to lower torque. Just the physics of it. I'm glad your setup works like a champ. A lighter clutch definitely shines while in the powerband. 5k- 8400 will be lightning. Just a dog to daily,.especially in traffic.

 

I don't dump the clutch or drag the thing. Regular driving, the car feels quicker off the line. On a lower torque car, the parasitic losses add up quickly.

Objectively, the car may not be actually faster. But it feels faster. Heel/Toe is much easier, rev matching is a breeze. The throttle feels telepathic.

Regular driving is fine, it's stop and go that I don't love the LWFW but to be honest I hate driving an air cooled car in stop and go traffic, so I actively avoid that anyway. The noise is probably the biggest negative.

 

The math will show that a light flywheel will contribute to slightly faster acceleration. But I’d say the biggest difference is increased “responsiveness”.

Here’s some interesting data about light flywheels:

I no longer have energy or patience for mods
but if I had a choice to pick OEM at time of orde4ring I will always order the heaviest battery and flywheel
year of racing and closet to 250k miles on GT chassis, LWF does you nothing good. you wont be faster at all. just a lot of king noises

 

I agree. There is no question the car feels more responsive. On a low HP car like a 993 that makes a big difference, especially with the way the car is geared for the US. On a 500hp GT car, I have no idea how it would feel.

I'm pretty light with mods nowadays. Numeric shifter, exhaust and wheels are about the extent of it. If someone is racing and we're talking lap times, the LWFW won't get you there faster but I will say heel/toe is easier so this could be considered a driver mod if anything (depending on the driver). Of course, if I'm racing I'd go PDK every single time.

Either way, it's not for everyone - I'm gonna bet there will be a number of S/T owners who really don't like the lightweight flywheel and end up selling their cars.

 

I’ll report back on that by end of the year. I have quite a bit of mileage on the R, but never truly daily’d it. But I may glutton for punishment.

Have you daily’d a LWFW car?

 

Yes. All 5th gen Vipers came stock with low inertia flywheels aka Light weight. Compound that with a modified clutch and Houston traffic and it's interesting to say the least. This is also why I made mention of the needed torque. They used the Low inertia right out the gate as the motor is a torque monster, but down low as others have reported and found out.... you have to nanny it or its easy to stall. The ACR-E has all the chatters so I can understand the lure.

 

my gt86 with less torque than a Milwaukee drives perfectly with a lightweight flywheel and clutch 😂

 

It will be a great scapegoat for flippers

 

lol. Did you see how many R came onto the market when the S/T was announced that had spent their entire lives in Saran-wrap and not even breakin miles ?

it’s cute folks don’t think the same fate awaits the S/T for at least a third of all cars. RL isn’t real.

 

it will depend on which way hybridization goes.

 

I agree. I also think most see that happening as well. There will be plenty of S/T's that sit but with double the production of the R, I'm hoping we see more S/T's on the road

 

 

Noticed the rubber chicken stuck to the A-Pillar!!!!!!!! lol

 

Illegal overtaking.
