The factory does not fit ant gas lifts. The most common setup is from Olthoff Racing.Hi Blas,
Here are the details on the rear clam gas shocks that are fitted to my SPF MK1 when it was delivered to me:
Gabriel Gaslift
Maximum Pressure 10 Mpa
4046-051115 350 NM
*Warning* High Gas Pressure
I am not sure if these were supplied by Superformance from the factory or supplied by the the company who fitted the engine and transmission etc.
They were originally white in colour.
I don't have any gas shocks fitted to the front clam.
I hope this helps and thank you for going to the effort of putting this manual together, it's something that is definitely required.
Rob.
