Thanks for all the great input guys! This helped a lot and I am happy to tell you that we will be able to deliver almost everything you asked for. Here are the initial specs of the CSS:
Material: Full aluminium with some steel parts
Mounting options: There will be screw inserts on the bottom. We will make an adapter for the Clubsport table clamp and the RennSport Wheel Stand.
Amount of gears: 7+1
Sequential option: We will implement it but only if this is not a compromise. We have a solution which could work very well in both modes
Haptic feeling: Very similar like in a real car. Perhaps we can even make the resistance adjustable.
Acoustic: A solid "clonck" instead of a "clack" but very silent
Colour/design: Silver as CSP. The shifter will be gated like in a Ferrari or Lamborghini
Style of gear knob: It will be exchangeable so upgrades are possible (leather, carbon, etc). The standard version will be an polished aluminum ball.
Size: We will try to keep the size of the PW shifter but it will probably become a bit higher
Compatibility: It will be backwards compatible to the Porsche wheel shifter and therefore compatible to all platforms. An USB adapter will be available optional to make it work with other wheels on PC.
Pricing: The target will be 99,95 € (incl VAT)/ 109,95 USD (excl. VAT)
Now we just have to make it happen. The target release date for the first prototypes is at the end of the year. We can announce a release date after we get the first test results.
