Before:

Stock clutch/pressure plate/flywheel - 53K miles
was very impressed with condition of all parts.. clutch/pressure plate assembly still looked like it could still take thousands more miles..

After:




Clutch Specialties: 1800 Pressure Plate with Unsprung Solid Hub Street Disk
AASCO: 8.5lb Aluminum Flywheel with replacable friction plate


First Impressions:

Pedal pressure felt same if not lighter than stock. First takeofs made minor shattering, at the time started to think I should of went with springs... As I shifted through gears, I noticed no difference from stock, since i don't ride the clutch through gears - this is the first thing I like about no springs (didn't feel like more stress on transmission).

100 miles later I was able to adjust better. I still get minor shattering from stop into 1st, but not from roll anymore. You also gotta re-adjust to downshifts - if you want to be easy on transmission. So far the only thing I gotta do is get the initial take-off down..

Flywheel,.. since I'm still breaking everything in, can't really tell yet

Will keep updated.

Side notes to self: avoid wheel hop
Side notes to others: If you're still at the stage where you ride the clutch into gears, get the clutch with springs

Part 2

200 miles now.. I can tell the car pulls better due to flywheel - eventhough I haven't pushed the car yet..

As mentioned in first post, upshifts from 1st to 2nd and up did not require more effort.. Its also a good idea to be easy when getting out for the gear.

Finally got more control over shifts from the stop.

Driving so many cars/miles with springs - I engaged as early as possible... around 1-1.5K RPM - as soon as it would grip. It was almost impossible to avoid minor shatter unless I concentrated like in 1/4 mile on every launch..

Solution: Tried to rev it to 2.3-2.7K before letting the clutch out - haven't had any shatter after that.

Looks like I'll be able to drive it as smooth as I did with springs (for normal/daily driving)

Will update once everything is broken in

 

Part 3

O.k. 600 miles now.. for past 200 miles I been increasing rpm shifts..

Clutch: got the shatter part down - whether the clutch broke in, or I got used to driving it - i'm able to control it just like stock clutch for daily driving + all the advantages of no springs.

Flywheel: i definately notice the difference in 1st, 2nd and 3rd gear. - not sure if 4th 5th is faster or just my imagination. - maybe until the vtec swithover.
Downshifts could be more violent now. - needle jumps from one rpm range to another within much shorter time.

Ovearall the car has much better pickup. - no loss of torque or whatever - accelerates faster from the start.

Flywheel for all motor

 

what are the benefits of an unsprung clutch? good review!

 

very good review.
