which compomotive Ts 16' wheels for ferrari mondial 8

One thing that you should be aware of is that the offsets on those 7x16 and 8x16 Compomotive wheels is a little less than what your Mondial chassis is designed for -- so they will be shifted outboard by 25~35 mm). I can't recall if the stock offset for your wheels is 44mm or 55mm (it might be marked on the back of the wheel spokes), but the offset on those Compomotive wheels is only 20mm (i.e., et20).
