170 Cloverleaf Clutch - better than standard?

I've just had my GT mapped at Red Dot... but I can't use it. I'm getting vibrations and clutch slip under heavy power, so I'm driving more cautiously than normal!!

Don't get me wrong, I'm very happy with the map, producing 197.5BHP and 340 torque. The car is 2008, 71,000 miles.

What is the standard Jtdm clutch good for?

What is the cloverleaf 170 clutch good for? Is it the same?

Having phoned AHM, they no longer fit upgraded clutches for tuned Jtdms due to problems (I think with torque). I read this on another website for upgraded clutches too. AHM said they're researching the market for a new one. They are currently fitting the best standard clutch from Alfa. I'm just not sure what the best standard clutch is capable of coping with.

Will a standard clutch last long with the torque?

When I renew the clutch, should I renew/upgrade anything else? Flywheel, Diff? I will spend the monies if it will better protect the drivetrain.

The 170 hp version has a different part number for the clutch, it should be slightly stronger.
Still there are stronger ones available as you can see in this topic:

The 170 clutch will be just fine. The problem with clutches is you don't know how they have been used before you owned the car. So many people just ride the clutch and kill it prematurely.

No need to touch the flywheel unless there is a problem with it.

Thanks
