Converting to front disks

it's up to you if want to convert to the 5X4.5 big bolt pattern or stay 5X4 small bolt, you can do the swap with factory components or aftermarket kits exist for both.

you can run the smaller big bolt pattern discs with most 14" wheels, there can be fitment issues with some aftermarket small bolt kits and 14" rims.

benefits of the big bolt swap are cost and availability of parts as well as selection of rims.

ultimately the choice between small bolt/big bolt comes down to budget and what the ultimate end goal is.

you can run mismatched front and rear, just carry two spares.
