I still have a little time before the order is locked in on my C4S.

I have ordered sport exhaust, -20 suspension and sports seats.

I remain unsure about ordering sports chrono. I know the throttle sensitivity/mapping changes with SC. Do you find that you really use the other feautures of SC all that much? ie the lap timer or the programmability options? Does the hard cut out at redline make much difference or the reduced interference of PSM?

Thanks for your thoughts. This forum is great. It influenced me to get PSE for which I am grateful having heard it now on another car
