Before I possibly indulge in a group buy purchase can anyone give me information/experience of using a lightweight pulley set with a subaru autobox ?
Car is a 1998 T/tb with the 4eat autobox and moving close to the 90k service. This would seem like a good time to fit a pulley set IF there would be any benefits to the autobox/engine.
I don't want to fit a set for purely cosmetic reasons and will not be getting an underdriven set, all oem sizes, just lighter.
If someone has tried this on an older car then I would really appreciate an appraisal of any noticeable changes, either good or bad.

Thanks
