Question Flywheel and clutch or just clutch?

I’m needing to replace my clutch soon, its making some pretty bad noises. I found a clutch set here: http://www.srmotorsports.com/sr86clch.html and I’m debating if I should fork out the money for the flywheel and clutch set or just the clutch? I’m not sure if its worth the extra money for the flywheel considering I don’t have any grand plans for my NA DD. I only plan on going in there once while I own the car so I want to do everything right, but a 9.5 lbs flywheel seems like overkill for going to school/work and back.... What’s everyone’s opinion on this? Anyone got a cheaper kit? Other options? Speak up!

You will love the 9.5 lb flywheel.

If youir worried about driveability get the ACT 11.5 Lb flywheel.. its a bit milder, but still uncorks your engine nicely!

I'm not worried about drivability so much as cost, I might not have been all that clear but my main concern is this: is it worth the extra 3-4 hundred bucks for a lighter flywheel? I could just take my old one and get it resurfaced for 1/10 the cost, but then again I really dont want to go back in there for any reason. Damn I just cant decide! Maybe I should call on my friend the quarter to decide.....

How hilly is your area? The stock flywheel is close to 30 lbs. The lightweight ones have a LOT less rotational inertia (lighter, plus less weight on the rim).

I'd love a lightweight flywheel, but when I was rebuilding my engine, I decided it wasn't worth the $400 or so. Now, I'm kicking myself for it. I want the spaztic revving of a light flywheel, though I'm not sure my tranny would be able to keep up (on upshifts & such).

the car will be 10x more fun

a rotary is pretty damn free revving as it is

i can't imagine how it'd be with a lightweight flywheel

yes its overkill

then again owning and restoring a car from like 1986 is overkill in some people's eyes as well

originaly I was going to say stay with the stock, but a good point was brought up about the fun factor level. If you can increas the fun factor of driving your car for 400 or less then it's worth it. You should rarely crack the transmission open from the engine block so when you do you might as well make any changes in the back of your mind. Go for it and dont for get to replace the through out baring.

Well I live on an island, which is a mountain. Around town is pretty level but leaving the area means going uphill. How much would a new flywheel effect hilly driving? When I first got the car I was amazed at how fast it was reving, I cant even begin to imagine how fast my car would rev up with a 9.5 or 11.5 lbs flywheel!

All this is wonderful to hear because I had the same doubts about the flywheel. I am currently in the process of changing my clutch and flywheel and I had a tough time deciding whether it was going to be worth the extra money for a lightwieght flywheel. I ended going with the ACT HD pressure plate, the SS clutch disc and the racing beat lightwieght steel flywheel and counter wieght that I believe is 17 lbs. together. This is on a 90 n/a vert that is a everyonce-in-awhile driver. Hope I like it.

The way even switching to the 17lb. (total, including counterweight) Racing Beat flywheel woke up my engine was surprising. I posted a video showing the sound of the supercharged engine being revved and people commented more on the fact that the car revved insanely quickly than they did on the sound of the car.

depends on the flywheel i think

i know fidanza does NOT supply the counterweight with the flywheel

you're supposed to use the AT counterweight with the fidanza as well

if its good quality one, go for it. 9.5 vs 30? do it......do it now!


if you really want it you should get it, but if you dont really need it or if the one u have now is fine.....just do what you want. if i had the extra 3-4 hundred id do it.

Remember most of those supposed 9.5 lbs flywheels end up being 12.5 lbs flywheels or so after the counterweight is put on.

i just got my 88 tII back on the road...it has a aluminum flywheel and the RB 6 puck clutch...fun? Absolutely...after you're rolling. Flat ground...you get used to it...starting from a dead stop on a hill or incline....you can't be timid with it. I think it's worth it.
