How much does the whole assembly weigh in at? Looks light.

On our postage scale the works was 16lbs 13oz. I think that is 1lb more than my aluminum setup from SPEC, but this is a lot smaller in diameter, so the moment of inertia should be very similar.

Just weighed the OE assembly (pressure plate, clutch disc and flywheel) 26lbs 8oz - this was used but only 1000miles, you can still see the machine marks in the flywheel, so this should be an accurate weight of a new one.

That was a nice little drop.

Could you through on just the clutch assembly with the bolts, if possible. Curious to see how much that heavy PP is.

Just got back from Willow Springs, shaking down the 2012. Considering how little it done to it when compared to the 99 car, it was fast. Just needs a little more tweaking, but a great first outing.

Stock pressure plate with hardware is 9lbs - the bolts made up about 3oz of that.

It is the area you circled, and to the left of it, he actually took it all the way down to the bucket area. From what I can tell the head got this treatment on both sides of the bucket, at every cam lobe.
