I believe I'm going to go with the act hd street clutch. The exedy I wasn't a big fan of and it can't hold a lot of torque, the spec seams to be the next best thing to act but its not much cheaper and I like the thought of having that extra cushion room on power. The fx300 doesn't have a torque rating that I could find and makes me a little iffy about it. I feel like the act will be my best bet with more mods coming in the future.

 

Now with the F1 racing LWFW I'm assuming I need to get the 06-07 ACT HD Street clutch kit and not a legacy gt one? I also noticed the sti had a cheaper price when I typed it into google shopping, I'm guessing I wouldn't be able to run that on my flywheel either?

 

STi trans is a 6MT so you can't use the clutch disc on that one, only on the 07+ Spec B. :(

I need to know what car I need to order the clutch for first haha. I'll PM him when I'm off work though, maybe he could tell me. I know some flywheels you have I run the wrx clutch and some you run the legacy gt clutch. So I don't know if I need the wrx style or legacy gt.

06+ WRX or 07+ Legacy GT are the clutches you want.

Flywheels will be for the same cars as well. You will also need Single Mass Flywheel Bolts as well, since your original Dual Mass flywheel bolts won't be reusable on the singlemass flywheel.

Here's my quick and dirty trick. Take a small crescent/box end combo wrench, screw a pressure plate bolt like halfway into fw, hook loop end of wrench on drivers side lower transmission stud coming out of block, rotate fw til you can seat the crescent part of the wrench between fw and pp bolt head.

 

Give her a test pull or two to seat it, make sure she won't budge on you, then break away!

 

Reverse and use opposite side of lower studs to remount :)

Well that way worked but I was nervous as hell, those things took everything I had to get out. So I go the flywheel out and inspected it and wow I'm embarrassed... I don't know if it was my driving or the guys before but there is a hot spot so bad it left a blue spot about the size of a quarter on the back side of the flywheel!:eek:

 

So I'm going to assume that that's too bad to try and resurface unless anyone thinks otherwise.

Well that hot spot is going to be hardened all the way through the flywheel, it won't matter how much metal is taken off there. I put it on out brake lathe at work and did one swipe and the hot spots and glazing is so bad it won't cut right on some spots.

 

I was told it had a fidanza LWFW on it when I got it and I like the thought of being able to replace the friction surface and not having to turn the flywheel. Anyone have any experience with the fidanza flywheels?

FWIW, back in post 22 is my Spec LWFW with the replaceable insert, I had my machine shop replace it with a new insert, It was $80.00 for the insert. He it was pretty easy to replace.

 

FWIW you should not turn a FW, it should be re-surfaced.

 

Hint, for better braking, you should also resurface your brake rotors like you do a FW.

After seeing that hot spot I wasn't about to reuse that flywheel but I was curious how it would react to a lathe. I'm curious to know if anyone has had any fitment issues or noise issues. And if I was to get an act clutch I wonder if I would need to get a legacy gt fidanza flywheel or a 06+ wrx flywheel.

The SB5-HDSS kit will require an 06+WRX flywheel.

 

ACT makes a streetlight and a prolite. Prolite isn't recommended for DD'ing as I think it's only 9.6lbs and will make your car throw a cel.

 

Essentially if you started from scratch, you'll be needing what ACT is sending back to me after warranty work. Of course I couldn't wait and bought a new clutch in the interim. But they did give me a new pressure place, refaced my clutch disc, and resurfaced my streetlight FW...I'll take it considering I bought the ACT setup 2 years ago. It'll find a good home somewhere.

 

But you'd need:

SB5-HDSS clutch kit

06+WRX FW--you can go OEM single mass or get a lighter weight unit.

New FW bolts, recommend you get the WRX as they have a hex head and not the stupid torx head, but if you already bought a tp50 bit, then guess it doesn't matter.

Check the condition of your tranny snout...TSK3 it, if it looks rough.

A guy at work had a t59+ do I just barrowed it. Max Capacity that you have a spec clutch also, I'm curious if getting the act clutch with a fidanza flywheel or one like it like your spec that can also have the friction plate replaced would cause any unusual noises or more importantly fitment issues sense thu won't be of the same company's.

Yes, LWFW cause noise. I have learned to coast down hill if I have to let off the gas to much. It makwes the tranny sound like a bucket of rocks tumbling down the hill.

 

If I didn't have the Spec LWFW already I would get a steel FW, my Spec LWFW weights 17lbs.

 

They say the 06 WRX takes hex bolts. After buying them I found the OEM hex bolts will not work with my Spec FW. I still have the new hex bolts hanging up in the shed.

 

I'm not sure if the 07-09 Legacy GT FW takes hex bolts or those stupid torx. I haven't looked into it.

 

As far as fitment. I'm betting the Fidanza is set up to accept a OEM style clutch kit. So it should work with whatever clutch company you want to use. Think about it, they wouldn't make it if it didn't accept any clutch. The clutch has to have the same bolt pattern as stock.

 

Also I thinking after having pulled both the tranny and the engine at different times. It makes more sense to pull the engine to replace the clutch. You gain a lot of open space to use a impact gun on the Torx bolts and then have plenty of room to work installing and lining up the new clutch kit.

Yeah I do the same thing coasting down hills because I got the same noise from a steel LWFW. the noise doesn't bother me too much as long as I know it's nothing bad going on. 17lbs seems like a good dd weight. I dd my ford ranger and use my car for night and weekend fun.

 

I really liked the responsiveness of the lighter weight so I'm for sure staying around 14 lbs or so like what was on it. The only ba things is I'm going to have to wait a couple weeks before I can order all of this, I was not expecting the have to fork out this much money. But as they say, you have to pay to play.

So if a 06-07 wrx flywheel works for a 06 legacy gt why would they make one for a 06 legacy gt also that's different? Im assuming a fidanza wrx LWFW can fit my car still sense the factory one will. I have noticed the 06-07 wrx one is about $100 cheaper than the 06 legacy gt one.

As the others said, the 05-06 LGT had a DMFW and DMClutch Kit as part of them trying to make the car more luxurious/smooth shifting. My CTS-V had a 55lb DMFW on it as well for the same reason.

 

Problem is that the rivets that hold the DMFWs together start to loosen up and cause vibration issues down the road, so almost everyone went back to SMFWs.

 

So the 06+ WRX and 07+ LGT have the same clutch setups. The 05-06 LGT has the same trans but a different clutch and flywheel. When replacing the clutch on a 05-06 LGT it is cheaper to get a SMFW + Clutch Kit than to get the 05-06 specific Clutch Kit, and the DMFW generally can't be re-surfaced.

The fidanza 06 wrx LWFW (part # 110251 http://thmotorsports.com/fidanza/fidanza_flywheel_aluminum/110251/i-264804.aspx ) is $217.72 an the 06 LGT fidanza LWFW (part # 110771 http://thmotorsports.com/fidanza/fidanza_flywheel_aluminum/110771/i-264805.aspx ) is $346.48. The question I have is does anyone know if the cheaper wrx flywheel will fit my legacy?

The Fidanza LWFW for the 06 LGT my guess mates up to the OEM DM clutch kit, whereas the 06 WRX one is made to mate to the SM Clutch Kit

And Mike's post I believe answered my question, I just don't see why they would make the LGT so much more.

 

Production scale for the SMFW is significantly higher than the production scale for the DMFW which was only installed in the LGT in 05 and 06.
