I'd say 205*50*15 fronts and 225*50*15 rears.
Hub conversion will also involve disc changes (but I'm sure you realised that!) I think Delta Integrale or Alfa 147 five stud hubs fit the rear hubs/Beta CV joints. Gerry does a five stud front hub conversion in a 98mm PCD that'll match the Integrale/Alfa rear hub pattern.
Alternatively I think you can convert the fronts using Fiat Dino Coupe front hubs which (and please check) are 108mm PCD, not sure what the matching alternative rear would be off the to of my head.
Obviously you need to consider which PCD you want first Tony, Gerry can supply the wheels in either PCD but 108 is the original size.
Hope that helps?
Cheers
Guy
