will be poo pood by many, but one option is going s14 front end.
would give massive track increase, maybe too much, but 5 stud straight out of the box and also big brake upgrade... 280 x 32 rotors with steel 4 spot calipers. Also no welding of suspension componants so engineering should be a sinch. i believe anyways
medwin has a 5 stud front end, his was a custom ford stub and hub i believe.
not sure on other options mate. Sure there would be a toyota option from some of the larger cars, but might cause problems with stub angle?
