New clutch, judder in 1st gear

[pvanosta]

I had some performance mods done to my '06 C2S Cab. I had 43,000 miles on the original clutch, and the increased power (turbo kit from Vivid Racing) would mean I'd shorten whatever life the clutch had left even further, so I decided to have it replaced.

The new clutch (Clutch Masters stage 2 kit) judders pretty badly whenever I try to start gently in 1st gear. The more I get on the gas before letting the clutch bite, the less judder I get. Thing is, that's not always practical in stop/start traffic .

My questions:

1. Is this normal?

If not,

2. Will this improve over time as the clutch gets 'broken in'?

or

3. Is there something mechanical I need to get looked at?

Thank you for any input/feedback

If the new clutch shudders I would have to question if the flywheel surface is uneven or needs replaced. Your kit came with new pressure plate, disk and TOB so nothing left but the flywheel. Just my guess here but with the added pressure of the stage 2 pressure plate I would think any irregularities of the flywheel would be magnified. And, as far as I know, it is not recommended to resurface the dual mass FW. It may smooth out with use but based on my experience I doubt it. Not what you want to hear but I would guess the clutch will have to be pulled back out to inspect and repair and needed...

Thank you for your feedback. Based on what I've read so far, you may be right, but it is also possible the new clutch needs to be 'embedded' or broken in and that can take a while.

I'll drive it for a while to see if things improve before taking the car apart again.
