Need clutch kit input...Clutch masters or Centerforce?

Ok so after a year + and well into 5 digits on my time attack cobalt, she's running and mean as all hell....Only new problem is the oem replacement clutch kit the previous owner had put in my 06 lsj (only >2k miles on it) won't stand up to the output if the car, rev limiter is set at 8800k rpm and clutch will only hold to about 6k @ wot.

So, being the car is going to be used to time attack competitions, we want to avoid as much down time as possible aling with being as competitive as possible so I was pointed in the direction of the

Clutchmasters04900-TD7R-AH Stage 6.5 Clutch Kit (Twin Disc) being sold by zzp for $1,574.99 before shipping.

So plan is to buy this today while the 10% vendor discounts in place,..,BUT
Then I seen TurboTech is offering 15% off and Josh w OTTP also is always willing to negotiate his prices so am wondering does anyone have experience w/ the
Center Force DFX Dual Friction Clutch w/ Aluminum Flywheel Kit that OTTP sells for $814.36 before shipping?
Or can tell me if they're comparable/torque ratings or just personal experiences with either, thanks in advance, Kevin

That's one option, If I were to go ky twin disk I'd want to buy an aluminum flywheel, I'd be back up around $1,350-$1,400,...

Option 2 is spec stage 3+ or stage 5 w/ spec aluminum flywheel for around $1,100

Option 3 is South Bend Stage 4+ w/ fidenza aluminum flywheel for $935.38

Option 4 is original plan the ClutchMasters Stage 6.5 Twin Disk for $1,417.49

Why aluminum? High power they can't handle and break out center hub of the flywheel. Most cobalt members use all steel for strength.

Your choice though

To eliminate 10.5-11.5lbs of weight from the crank is why I would think aluminum is what I'd want, but that's why I'm asking,.....
