Have now done 200 miles in the past 2 days and I've thrown every road surface imaginable at the comfort kit - it is a complete transformation - even the bumpiest surfaces where the front wheels are hopping up and down don't translate through to the steering wheel anymore. 10/10 for the comfort kit and highly recommended.
Likewise the Centa drive compensator has irradicated the death rattle - there is perhaps a little more driveline vibration at just under 3000RPM but it's a small price to pay. It's just great, after more than 2 years of ownership to finally get rid of that rattle!
Cooling fan seems sensible, particularly in this weather. I didn't bother with the NVH pack as the bevel box noise doesn't bother me that much, and I really don't want to add more weight to the car.
I've also changed the pedal box to the later type, which by re drilling some new holes further to the right has allowed me to takes the pedal box another 2" forward. At 6'4" this has made a fantastic difference to the overall comfort..
So overall I'm very, very pleased with the updates. If you only do one, and you drive on poor road surfaces, then I'd go for the comfort kit
