Lightened flywheel or stock
I'm upgrading to a 250mm rb flywheel and 350z clutch. I bought a stock flywheel, and then came across an awesome deal on a lightweight one that I couldn't pass up, so I have both. The car is my daily driver, but will see racing and launching about half a dozen nights a month give or take. My question is will the bigger surface area of the flywheel make launching the lightweight flywheel any easier (the clutch is full faced so I'll be able to slip it), or should I just put the stock flywheel on? |

I'm not sure about launching, but I do know that lightweight flywheels make a good difference and are still very street able. I have a Fidanza piece on my MR2 and the difference is amazing. It takes some getting used to because your RPMs will rise and fall a little faster, but the response is quicker torque wise and your power band is a little more progressive in the end. Putting the lightweight flywheel on won't hurt anything.

I liked my stock flywheel better in my SVT Focus then the guys I test drove with the light weight alumium one. For raciing, I think light is better, but for a DD I'd stick with stock'ish weight for the better low end.

I liked mine in my integra. I went from stock 18lbs to a 12lb flywheel. I could see an 8lb being annoying on the street though. But given the option to use one again, I would.

im going from 22lbs flywheel to 14 lbs lol should be interesting but one is dual mass and the new one is single and also a little larger.

I know going from a dual mass(22) to a single light way(12) in my 350z caused alot of chatter that drove me up the wall. I'm not sure i'd go the same route in the GTO not a big fan of rolling into a parking lot with my car making a awesome chatter sound.

Hm, I'm pretty sure the stock flywheel in a ka is ~20 lbs. and I'd be going to a 12 lb. rb flywheel. I opted to go this route so that I didnt have to run a six-puck because of the chatter and engagement. I want the car as streetable as possible, but I still need something to support the power. After a bit of research, I'm leaning towards running the stock rb flywheel (~24 lbs).. kind of going the opposite way in terms of weight, but I really dislike chatter, and I'd like to be able to launch easily.

I went from the stock dual mass flywheel (28lbs) and unsprung clutch in my car to a Fidanza (12lbs) and a Clutch Masters Stage 2 sprung Carbon/Kevlar. this worked out perfectly. the car is dd and a breeze to drive. launch, and control in general. the lighter fw made the revs come smoother and quicker. made "spirited" driving much easier and more enjoyable. I'd go lightweight f/w and pick a clutch that suits your needs.

Forgot to update this thread. I basically decided to go the lightweight route because I dont want to regret not trying it while I have the tranny out.. I already know how the 24 lb. flywheel is going to feel considering I've been running the D21 flywheel (24 lbs) for a while, so I'm going to give the lightweight a shot. I know a friend of mine had a 240 and was running an 8 lb. flywheel... he said it was streetable, but it was tough to tell when in his car because he was running a six puck. I'll be running a full faced carbon kevlar, steel backed 350z clutch, so I guess we'll see.

If you're driving the car a lot everyday in traffic I would just stick with the regular flywheel/disc setup. It's not really worth the hassle for the smaller percentage of time you'll be driving fast. I just noticed that this was going into a nonturbo ka s13... I would really advise sticking with the stocker and putting the money towards something else.

Forgot to update this thread. I ended up using the lightweight one and its super easy to drive even in stop and go traffic on hills. It took me like 5 minutes to get used to, especially since I changed the engagement point of the clutch several times after I had everything together. Also, I put ka24de just because I'm so used to writing that and never really put the "t" at the end... this things turbo (ka-t) and should be somewhere around 340rwhp.

for everyday driving the light one is better. if you are into launching the car heaver is better.. most of the domestic peeps who are into drag racing actaully put heavier flywheels in. After you have drivin it forawhile let us know what u think. Im curious how it is for your car.

My car came w/ a light weight RB flywheel (ka24de also, boosted...) & 350 clutch, drives pretty nice, but cant compare it to the stock one. Last edited by Car6on14; 05-06-2010 at 02:52 PM. |

Well to update this thread the lightweight flywheel took a **** on me. It randomly started having this problem where the starter would make a weird ass noise when I started it like it was fighting with the flywheel and sometimes it wouldnt start until I push started it. At first I just thought it was the starter, so I replaced it and still the same thing. So one time when it was at home and wouldn't start I pulled the starter and saw that the flywheel dipped in at that one spot. It's right where the little oval chunk is taken out to get it lightweight. It just kind of became concave there. Good thing I didnt sell my other flywheel. I'll update with pics on that when I drop the tranny and throw the heavier flywheel in.

hrmm, how light was the flywheel? So it was machined steel flywheel, not an aluminum one? What brand is your clutch ACT?
