Flywheel machining, actual cost
#21
My flywheel is around 8lbs and is totally streetable. I've never stalled the car or had any issue. I wouldn't do it again since I don't think the performance gain is justified considering the cost. In fact I think paying anything for a lightened flywheel (stock or otherwise) is a waste of $$$ on a FI'd miata.
When you had the flywheel balanced did you get the PP and Disc done as well?

sorry, didn't mean it to come off like gospel or anything
looking around at aftermarket lightweight flywheels, the "race" designated wheels are around 8-10 lbs and the ones designated "street" are around 12-13 lbs.
maybe there's not enough of a difference in rotational mass to matter and it's just marketing, but that's my observation

I heard everyone saying that too, so when I bought my 8lb flywheel and ACT Extreme clutch, I was worried it would kill the driveability. Even the first day debunked everyones comments about not being able to street it.. I now realize that I heard it mostly from miata.net, which explains alot. After two weeks I got so used to it, that it was actually harder to drive my friends car with a stock clutch.

nahhhhhhhhh. my whole rotating assembly is like 15 lbs including flywheel, clutch, and floaters. plus it's smaller diameter. it's only a bitch because of the mazdaspeed shifter and different type of engagement feel than stock.
but it's not hard to drive. just notchy. OH that reminds me... gotta find some good gear lube. brb.

Is it really that bad? I know alot of people complain of the same noise. I think mine may have made it alittle bit louder but I really didn't notice much. My flywheel is aftermarket tho, maby thats why, idk.

I've been wondering about this.
I'm going to be doing the clutch eventually, and I almost always to a lightweight flywheel when I'm putting in a new clutch. I heel toe subconciously now, so any weight lost seems worth it to me.
I'm thinking that I'll just machine some off the oem. Does anyone know why it creates the excessive noise?

Jason, if you had no rattling in your tranny to begin with, you may not notice any increase in noise because there isn't enough to get amplified.
If your tranny's old, tired and beat-up and made noise with a stock flywheel, as mine did, it'll almost surely get worse with a lightened flywheel...as mine did.
