Im getting another clutch sometime this week and Ive been hearing about lightening my stock flywheel. How is this done is the meaurements done by the machine shop or do I have to do it myself? Can somebody please point me to the right direction.

 

Measurements are made by the machine shop, finding a shop that specialises in flywheel weight reduction is the best bet.

A good shop will resurface the flywheel, remove material from the "back" of the wheel only, [to maintain proper height] leaving material along the outside edge, [for better inertia] and the hub, [for strength] a "re-balancing" should also be done. 94

 

You are so much better off just buying a quality light flywheel. You will have as much if not more in your OEM flywheel by the time the machine shop lightens it and if they do it properly with a full balancing (not many shops can do this btw) it is still a time bomb if you rev your car in the 8-9k range.

 

thank you for your input in this.

I dotn rev past 8k I barely even reach 8k when revving.

 

Yea you can definitely buy a light weight flywheel from Exedy or Fordenza.
Best route to go.

 

I would buy one. Like said before it will almost be the same price after all the work, plus you will have a little more reliability.

 

For a DD it is absolutely not the best way to go.
If you have had a light weight fly wheel in a DD you would know this, it is not practical. 94

 

Light weight fly wheels and performance clutches def suck on a DD! But you get used to it... It's just that everyone thinks your trying to race even if you're just driving normally...

 

eh, i like my itr flywheel in my gsr swap. its a good bit lighter, and the car is still very easy to dd. it makes it so much easier to rev match when playing on a track, or my 3/4 mile, twisty, paved driveway (thank you rich neighbor lol) in my experience, a 12 lb flywheel seems to be a good balance between driveability and performance.

a friend of mine had an 8lb on his d16z6 swapped ef, and it revved like a crotch rocket, but it was really easy to stall unless you drove it like a ricer lol
