Been reading threads for over an hour, and everyone conflicts the other one. My tib is an 03 GT with a born on date of February 12, 2003 (a day before my b'day). I've searched and read about the HY3 and the HY5, and how Fidanza initially sent out Elantra and and/or wrong flywheels to buyers. I've read about bad installs etc..

Can some clutch guru out here tell me the correct flywheel and stage 4 package to get? It's time. It's slipping really bad. I've done clutches on domestics, and Harleys, but never an import hydraulic. I thought I could do it from below, but some are telling me it's too difficult to drop crossmembers, and pull axles, and that it's easier to pull the motor.

I'm at a crossroad here. I'm either going to solicit some help from someone that's done this before and wants to make some side money with me doing most of the labor, or take it to nextgen if available or the dealer.

This diagnostic guide was made for centerforce clutches, but has some good trouble shooting info for any clutch.

Fidanza and Ultrarev both say that 99% of the time, FW #193461 (HY5) is needed. THe HY3 is sometimes but rarely needed. Evidently Hyundai was to have a cut-off date for the earlier type FW but didn't completely cut off, so some of the older style FW's were used in production past the proposed cutoff date, and earlier lightweight flywheels were not fitting.

I was concerned because my 03 fit the TSB where the clutches were screwed up prior to April 03 build dates. This made me concerned that I may have the older type flywheel. Like they said, order the HY5, and if it doesn't fit, they'll exchange it. Also, Fidanza advised that the HY3 will fit in and HY5 application and later fail because the starter won't mesh correctly and chew it up, but an HY5 won't fit in an HY3 application at all. I was concerned the CM stage 4 that TC and CM's recommended was excessive for my setup, but I'm about 300 chp, and both said the stage 4 isn't that rough for street and doesn't shift badly, and that I would kill a stage 3 early on.

I'm reading a lightweight flywheel will get a little more power to the wheels as it takes less force to move the aluminum flywheel.

Bagpiper, if you havent already bought the clutch i can get you a CM stage 4 with an unsprung disc so you wont have to worry whether or not it fits.

Is this above statement true? Will an unsprung stage 4 Clutch Master clutch work with both the HY3 and the HY5??

(Sorry to dig up the old post, but no one seems to answer clutch/flywheel questions around here)
