Our member Jan A Aune have this nice 1988 model

The wheels are 165 / 70 TR 13 up front and 205 / 60 HR 13 at the rear with aluminium rims from Melber. The wheels are approved like that from TÜV. So then it should be possible for others to set up their cars with these wheel dimensions too! Black leather interior and a four pipe ANSA exhaust system. The suspension is lowered. The X1/9 looks so very Italian in yellow! A really nice car Mr. Aune!
