Default Recommendations for streetable clutch/flywheel combo?

Post up what you're using, and what for (DD, autox, ring racing etc) and how long for.

I'm looking at Exedy/Daikin OEM replacements or ACT "Street" packages.

When replacing the clutch & flywheel, what replacement parts are you buying ?

A clutch kit usually consists of clutch, pressure plate, pilot bearing, throw out bearing, and alignment tool. All of that should be replaced when installing a new clutch. Also you should have the flywheel resurfaced at the local machine shop. If the flywheel has any cracks in it dispose of it and replace it. The flywheel has a min required thickness so if it's too worn dispose of it. If you are doing the work yourself use medium hold thread locker on the flywheel bolts when reinstalling. I also recommend replacing the spring clips on the clutch fork for the throw out bearing, as they tend to stretch over time and get sloppy, plus they are cheap to replace.

The Exedy stuff is good and fine if your car is close to stock. RPS makes a nice clutch kit too that uses the OEM Exedy clutch with their own pressure plate that has a bit more clamping force. Unless you're making 50+ more WHP then stock I wouldn't bother looking at anything else.

My cobb lightened flywheel is the best mod I have ever added to any car I've owned (performance-wise, as I've had some pretty fancy stereos that were great mods). That's the way I'd go as far as flywheels...

I'm thinking about just sticking to an OEM Exedy clutch kit, 5mt snout repair kit and the Exedy lightweight flywheel...
I was pointed out the fact that the Exedy flywheel is a single piece unit, whereas the others are multiple pieces put together. I need durability and longevity more than I need fancy engineering.

I have a quote for Exedy Stage 1/ ACT Flywheel for $449 Shipped...

I had an ACT Streetlight lightened flywheel in my 02 Sedan I once owned. I thought it was great as well. The throttle response was terrific. I also use one in my Mustang. I hear people say they don't like the lightened flywheels because they think they throw trouble codes, or that you lose torque. I have not seen any sufficient data to support this though. The down side is the cost of them.

Exedy flywheels for your car are not aluminum. Not saying that you thought they were, just pointing this out so the facts are straight.
http://www.exedyusa.com/race/FF02

Quote:
EXEDY Racing Flywheels are made from solid one piece billet chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response.
Most incorporate special design features to enhance air flow to improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and have the possibility of separating from the flywheel.
It would be nice if Exedy published the weight of the flywheel so we can properly compare it to other available pieces.

I've never seen an aluminum flywheel that wasn't two pieces. So far as I know this is because aluminum is a horrible metal to use as friction piece. If it was good then we would see aluminum brake rotors, but we don't. We see two piece aluminum top hats with steel rotors. This works the same for a flywheel, aluminum backing pieced together with a steel friction surface.

Cheers for the info - I have read the Exedy site, and have a few price enquiries in with some dealers.

According to Tarmac USA, the Exedy chrome-moly flywheel is 14lbs. Which is a reduction of about 10lbs over stock IIRC. I know some people who have the Fidanza 9lb fly on their Imprezas, but I don't want to go that far I think. I'm not as good as them at shifting.

14lbs is a good weight for a street driven car, and you have good reasons for not going lighter. In my experience, there's a big difference felt when you reduce from ~25lbs. to ~15lbs. Not so much is felt between ~15lbs. and ~9lbs.

I put in a ACT and Streetlite Fly Wheel (13.8lbs)... the factor Fly Wheel is 28lbs.

Car revs up great and handles the 300+whp I'm putting down just fine.

My car is a daily driver and very easy to drive. I will be auto-xing and run a few drags this year.

My buddy did the same clutch but with the ACT 9lbs flywheel... it is rev happy but he says if he did it over again he would go with the streetlite.

Also, at least on the 2005 LGT the OEM clutch was made by SACHS not Exedy as in the WRX/STI.

Good luck.

I have also hear good things about SPEC clutches.

It's not like you're turning it into a dog-box or anything. You'll get used to it, and you'll like it if you like shifting fast. I've got the 9.5lb Fidanza, had it for 70k miles now on the DD. Car also sees AutoX, RallyX, and track days.

ACT streetlite is one piece fw as well its a little under 13lbs. The Fidanza is the one with the inserts for the grip surface...

ACT does make a prolite or something that's 9lbs as well IIRC that's one piece too if you really want to get that.

I seriously wouldn't go lower than 14lbs...at least if you drive in traffic or city driving often...

I also wanted something very streetable, but hated how long it took my revs to drop, so when it was time for the clutch to go, I upgraded the flywheel too. i looked around for the heaviest aftermarket flywheel i could find specs on (in my limited ability to navigate the internet for legacy parts), and i came up with the ACT streetlite (13+lbs). It was also a good price compared to many, and still a significant weight reduction. I paired it with the Exedy organic clutch, and I've used the combo for 5-6k miles so far on long trips, daily driving, and rally crossing.

It does feel a little more lurchy than my stock STi setup, even though it doesn't grab as hard, but it never gives me problems once everything is warmed up, and I'm not trying to drive like grandma any more. I am curious to see how long the new clutch lasts, though, since I smell it a decent bit when I play in the dirt, forcibly spinning my wheels.

Considering I have it on my car, yes, it is a one piece.

We run a Fidanza/Exedy combo on our Outback. Really helped the revs and very streetable. Also got rid of the chattering issues.

I've got an ACT Streetlite and FF1 Stage 2 clutch going in my 98 Legacy as soon as I get my tax return. I read a deal in the drivetrain section about FF1 being made my Exedy and sure enough, when it showed up it had Exedy info inside. Cost $250 shipped to door from E bay.

Bully Performance Clutch - http://www.bullyclutch.com/
Kevlar 6 Puck Clutch (STI Version, Pull Type)
Release Bearing
Custom Needle Bearing pressure plate
Pedal pressure = OEM + 5 lbs
Stock STI flywheel

Car is used for many motorsports applications, Time Attacks, Autoslalom (Solo II), Pro-Solo's, King of the Hill events (see video below).

Can't complain, they are one of the best, most approachable clutch manufacturers I've ever dealt with. Simple as a single phone call to resolve issues, if any.

Competitors eye view, this car is a 2.5 RS with an STI version 8 swap, against my overweight Legacy.

I've been using a Fidanza 9.5# (or whatever it is) since early 2002. I'd have to go back and look at my records, but I have somewhere around 100-120k miles on it. I had Rallispec change out the friction surface when I did some other tranny work back in '05, but it probably wasn't strictly necessary - just figured I might as well do it while the had the tranny out.

I spent 3 years doing stop-and-go driving to/from work in HI and didn't find it any more annoying than driving a stick with a "normal" flywheel in the same traffic. Manual tranny + stop-and-go = annoying no matter how you look at it IMO.

I don't even remember what clutch I'm running. I think I had a Clutchmaster Stage 1 before, and now it's an Exedy - I think. Clutches always seem to me to be complete guesswork. For every 5 guys that say their ACT (or Exedy or CM or whoever) clutch is the greatest thing since sliced bread, there's another 5 guys who say their ACT chatters like there was no tomorrow and slips all the time. I can't figure it out.
