Hi guys, new to this site and could do with your help. I have acquired an Autotune Aristocat (XK140 replica) that has 1972 Series1 XJ6 running gear. The rear tyres rub on the sides of the wheel arches; and just looking at the car, it would appear to sit about 1” too low at the back. What would you suggest is the best way of overcoming this – longer springs perhaps? Many thanks Craig
