Well, the clutch is slipping a bit when floor it around 4k RPM or so. Will be installing a Sachs clutch kit.

Trying to decide on either:

A. Getting the AASCO lightweight flywheel; $750 through UltraRev.com

-or-

B. Getting RSS plenum for approx $750

Have already researched possible chatter issues with the LWFW which for me is a moot point. Going to do install of clutch myself (have done clutch/transmission installs on VW Jetta's and automatic trans to manual trans swap on a '90 300ZX Twin Trubo so not worried about the complexity).

Suggestions on the above? A or B? Need to know pretty quick as I would like to order the needed parts today or tomorrow so I can install the clutch next weekend...

 

If you are replacing the clutch and intend to drive aggressively in the future, i.e. track events the LWFW is the way to go.

 

^^^^ +1, LWFW... The plennum is a 1 hour job, you can do that anytime.
