I continue to run in the car, nearly 1100 km (and a oil change at 500) had been done so far.
Everything run smooth for the moment.
Still a little problem with the new airbag but soon i'll go to the official GTR (R35) belgian dealer who should have all the necessary to check and fix that.
I 'll try to post pictures of the different places I go during the run in (even if the weather is not very good for the moment).
Lac du Val Joly, France
Barrage de l'Eau d'heure, Belgique
First snow :) (Just leave the car two hours outside in front of my flat and found it like that)
