Got this done today, with the clutch change, driving is so much different. Shuddering is gone...

Weird though, after the clutch change, my blow off valve sound (you know that distinctive Pfft at the sound of the gear change) is completely gone, there is also a slight more induction noises all over the place (the experts noticed it too when test driving, driving home, I noticed it as well)......... have emailed them, hopefully it was just something that they forgotten to tighten or something when putting it all back together.
