yup its right but fiat/alfa replaced the old variator with the plastic parts later on anyway. never used the GSR one myself, but heard the same stories.
the newer standard variators seem to be ok, and last longer than the old ones with the plastic internals
Same story by e-mail from GSR.
Due to the fact that the variators have improved in quality we do not supply the uprated variator any longer.
We now only supply performance tuning items for Alfa Romeo and other makes.
So, I guess, my 147 1.6TS having the variator that came with the car back in 2001 (88.000kms now) I should just change it for a new one and get it over with.
