Weight difference 993 RS CS (RSR) and 993 Cup

[swe993rs]

All these questions from a snowy Sweden.....

The weight for both the 993RS as well as the 993RS CS (RSR for you in the UK) was quoted as 1270 kg. The extra weight of the full cage equaling the weight saving from having no carpets/interior in the car.

However, the weight of the 993 Cup car was only 1120kg. The 150kg weightsaving, what was this due to? I would assume the following;
No heating package
No handbrake assembly
Only 1 seat

What else could explain this??

Why am I asking? I am looking at buying a 993 RS CS. I will try to attach a picture of the car once I haev figured out how I do it....

As a starter for 10 (kilo's give or take), I'd add space-saver spare wheel and toolkit.
