I'm considerin maybe getting an aluminum flywheel (never gona get this car back together if i keep doin this lmao) and was wandering how streetable they are? i was thinkin i read somethin awhile back they were a little harder get use to driving. also a pro/con thing would be nice, all i know about em right now is the obvious lightweight and quicker revving.. thanks in advance.

 

Depends on the weight of the car, rear end gears, etc. But overall, I'd advise against it in a heavy car like a 4th gen.

i put one in my 99z, mated to a SPEC 4 clutch.

the cam in the car makes starting a bit touchy as it is...and i know htis cause i ran the cam for a few months on the stock clutch/fw.

now running the spec4 is also tricky since it is a solid disc, not much slipping with it.
so pulling out with the light flywheel, with MUCH less rotating mass to keep engine inertia...and no clutch slip...it's a bit tricky.

but once you get use to it i don't think it's all that bad.

the hardest part i find is backing up. when you want to pull out of a parking spot slow...since you can't just slip it. it's kindda a go or no-go deal. which is tricky.

but pulling out from a stop really isn't hard. like i said alot of my difficulties are derived from the cam as well.

man does the thing spin up fast though...


honestly...if you do alot of city driving...i would also look elsewhere. maybe go with a billet FW that is only a few pounds lighter...not the 12.5# alum fidanza unit. i wish i could tell you how it drives in a tamer car...with a tamer clutch...

 

mm thanks for the info teke, that quick rev is the big thing i was lookin forward to about it. I'm just curious as to whether its worth it or not.. and also someone told me teh aluminum flywheels are easier to mess up? makes since because aluminum is a little softer but how much easier?? (full bolt on 94 Z28 w/ 3.73 gear and zoom kevlar clutch) or also to another point.. how bad does a flywheel have to be before it needs replacing anyway?!.. as far as driving this car is a DD.. but it doesnt see bad city driving like most are use to, small city most stop and go i see is goin to wal-mart. also how would this affect 1/4 mile times?? i know there more for road racing, but how badly could it hurt at the strip?

 

I have the fidanza AL flywheel on my z28 and I love it. This is my daily driver and I dont any problem with it in stop and go traffic. It does rev up nicely too. You dont need to be concerned about the durability of the flywheel b/c there is a steel face that contacts the clutch disc.

10 lbs of rotating mass savings!!

 

I second that! I have the Fidanza, and had it behind my Feeble305 at first. It was sprightly. Now with it behind the Minirammed 385, it is wicked-fast for revs, and I experienced no shudder or driveability loss with a SPEC stage 2 clutch. I've just installed a stage 3 clutch because the mid-12's at 114 MPH ate the stage 2 after about sixty "granny-launches" last season.

I'm sold on the Fidanza. Nice piece, and as nfa says, it comes with a steel thrust plate that is REPLACEABLE. I had to replace mine and it was rather easy once I found the proper inch-pound torque wrench.

 

thanks guys, i may be gettin one now thanks to all this new info, just depends on whther the shop starts on the car before i can get one in or not

 

Good info, mine came in yesterday. My bellhousing is cracked so I decided to go with a McLeod Clutch and Aluminum flywheel while the tranny is out, since I have a sick set of heads and cam ready to go in. Now I can't wait to try it out.

 

you can see the steel friction plate on the FW on the left of this photo. this is of my SPEC 4 and fidanza fw



just an FYI...i got my flywheel for $299 SHIPPED off ebay. that was about $50 cheaper than anyplace else i could find it. just do a search, they may still have them for sale.

 

What granny was driving your car Dan?

 

And here I was thinking that I got a good deal at $335. You scored an amazing price!!!

 

Damn, I thought I scored a deal getting it for 345 and free shipping from gripforce clutches on ebay. Summit and other places wanted 430-480 so I saw 345 and free shipping and jumped right on it. I noticed mine came with some weights attached to one side, does this mean it is zero balanced?

 

LT1 motors come externally balanced from the factory. You have to bring the new flywheel to a machine shop to have them match it to the old flywheel. The weight is there so that they can drill out pieces of it to match the two flywheels. If you are using a new pressure plate, its advisable to get it neutral balanced while you are there. Mine was off by about 15 grams and I cant remember how much the flywheel was off by.

 

... O_O glad you posted that! i had no idea that i needed to take my old flywheel and have the new one balance mathced to it... u just saved me a lot of trouble. now i just have to get my dad to find the flywheel of the new engine!! =/ and take it to the shop before they start work.. grr more delays.. =/

 

My engine is a traditional SBC (ZZ4) and comes internally balanced. I was told that this Flywheel is at zero balance right now and can be bolted right on, is this wrong?
