Thank you for this information! Really appreciate you going through each part and talking about their uses and advantages! Will be buying this car soon, getting back into touring car after many years away from it and this will be my first Schumacher! :)

Enjoy your car mate!

Robert, why does raising the driveshaft angles change the grip to a lower grip? thank you.

[@RobertKrens]

Rasing the diff's (with the excenters and/or the bulkheads) and thus making the driveshafts more straight will take away (lateral) grip. It will give a little more rotation.
