roadblock

Hello all - I have purchased a lightweight flywheel, next I need to order a clutch - Does it matter if I get an LUK or Sachs would be better?
I will also replace slave and Ect while I am in there. Please advise Thx

Do some reading here on the lightweight flywheels. Some have attributed flywheel end main bearing failure to the use of a LW flywheel. Has been discussed here.

The rotating mass is huge for stock FW I guess that's the trade off

I purchased LwFW from pelican 6 months ago don't know if they will take it back?

Avoid using a LWFW if you don't want to shorten your engine's life. Jake has explained many times.

I'm not sure if either is better, but Luk is the OEM manufacturer of the dual mass flywheel, Sachs makes the OEM clutch/plate/bearing. I went with the genuine Porsche clutch kit from suncoast and it was all Sachs parts.

I went with the package from Patrick Motorsports.
It was an Aasco LWFW, Sachs stage 2 sprung clutch disc and pressure plate.
It came with all new bolts and the set was centrifugal balanced.
Right around $2000, for the set.
You will see a lot of threads here covering the yes or no use of a LWFW.
With an underdrive pulley from RSS, and other modifications my motor revs very quickly.
Will it shorten the life span of the M96?
I guess you can just add it to the list of my so many people make remarks about an M96, being a time bomb.
From the IMS, the poor designed oil filtration, spun rod bearings, piston pins letting loose.
If you live in fear of your motor gernading, sell the car and buy a Prius.
If not, do what you want and enjoy the hell out of it.

All of the SP996 guys I know run LWFWs. Barring any money shifts these engine hold up amazingly well for racing.

Thanks for info- stage 2 Sachs and def not afraid of anything this car can throw at me - Racing will rid you of much anxiety of what will break next- it's a learning moment and love digging in. Do you also run 997 shifter ? I will get one of those as well with cables

Need to get underdrive pulley - thx

Be selective on pulley
Don't buy one with a bunch of holes machined into it, it looks good for light weight, but makes it weak.

That's why Jake feels like he's talking to a wall. There are many experts on the internet but as far as m96 engine is concerned, I tend to listen to Jake, Charles, and Baz. Of course it's your car, you can run anything you desire.

Exact reason I had mine removed and replaced with a brand new genuine flywheel.

Was exciting to drive around with it though, such a great modification if it didn't put the engine at risk also be aware of the noise it creates when the car is in neutral.

I found myself quite often holding in the clutch (for short periods whilst stopped) so it didn't make any noise.

Some are willing to sacrifice longevity of motor to all out performance - Will it be a 100 k motor or a 10 K mileage motor ( I am sure Jake would like more business) I personally went 10 10ths on a 3liter 4 cyl 720 hp with a life of 40 hours of racing- to be sure different strokes for some of us- the more horsepower and launch does come at a price or smiles per mile

I just want to help but as long as it's a conscious decision and you know the trade off, I have nothing against your decision.

Forgot to add, in the engine rebuild class, Jake also explained why the LWFW will cost you performance that you don't even know, in addition to why it is bad for the engine.
