Anything and everything Vitesse.

After acquiring 1500 Spittie with a severe case of brochitis we had a full engine service at JY Classics only to learn that the car is fitted with SU6's and not '4s which is contributing to what is still an underperformance. Now why should anyone do that? Would anyone like to swap a pefectly good pair of '6s for a working pair of '4s?
