stock clutch vs sport clutch?

[4agdtym]

I am about to buy a new clutch. The Pelican kit is about $500. The Sachs sport clutch components are about $1100.

What are the differences? Lifetime wear? Torque handling? Other issues? Is the sport clutch worth twice the price?

I'll be installing this with a 3.8 liter engine.

Thanks,

David

From looking at your mods would you be considering a Lightweight Flywheel (Aasco)? The North Texas Boxster Enthusiasts have several members, soon to be another-me, running LWFWs and LOVING them! The car revs faster but it also de-accels faster too. Maybe not your cup of tea BUT WHAT A BLAST! My ride is almost back together after a Stage 2 IMS failure and i am doing some of these mods while I'm there.

Also, Spec has SPRUNG clutches but they are $600 - to be used in conjunction with a LWFW - do NOT used with a stock dual-mass boat anchor! Mine Flywheel weighed 38 pounds! The Aasco weighs in at a mere 13 pounds….closer to 20 pounds with a clutch and housing installed! That is a LOT of rotating mass that will NOT rotate on my car any more! 3.8 is a LOT of torque….you may be in Spec2 or better territory! Sachs certainly will NOT be satisfactory! Why let all those horses go to waste at the Flywheel?

I've thought long and hard about the lightweight flyweheel option. I've decided against it. I wanted to have my stock flywheel lightened a few pounds, but the dual mass structure made the machine shop refuse to do it since they didn't know how to take it apart and put it back together. New Porsche casrs with 3.8 engines are running heavy dual mas flywheels just fine. Maybe there are times we should trust the Prosche engineers to know what they are doing.

My question really had to do with the differences between the disk materials, spring rates and such and whether or not they warrented twice the price. As one of my car buddies pointed out, the weight of the Boxster and all that torque, the likly outcome is going to be a lot of wheel spin even with the stock clutch. There is really no need for a sport clutch. I've gone to wider tires to help with traction (285 in the rear). I'll see what happens. I hope to have it on the road in a couple weeks.

I will take my time learning how to drive the car with the increases in power and torque as it is. Down the road, if I change my mind, there is still room to get more if I want.
