Laust- how heavy were they? which stock seats did you have?

 

I didn’t weigh them. As I recall, they were somewhat lighter than the stock seats.
The original (1988, 951) seats were almond colored, standard (not sports seats), electric driver adjustment, manual passenger adjustment and starting to crack here and there.

 

I have similar with the ability to tilt and perforated vinyl. They look nice but I had problems with the "universal" sliders and had to drill some holes in them but that didnt help the extremely slight width mismatch. If you can fabricate brackets to overcome the slight dimensional differences and dont mind the implications of you get what you paid for well...

also, if you have power seats the seatbelt bracket will be tricky and my require some fabrication as well.

I still have a pair that dont tilt but I need to clean them up before I can sell them on ebay along with my original porsche old and worn seats.
