Wheel Hub/Bolt Pattern Change

[KingNothingIII]

Hey everybody. First post on this forum. I have an 04 Baja Turbo with a 5 Speed. Call me crazy, but I'm really in to the soft swept wheel design of the 90s. Think Pontiac Sunfire or Subaru SVX. I'd like to put the SVX wheels on my Baja. I could use wheel adapters but I also do some soft-roading near my farm with good dips and rocks on the trails. In addition to towing and hauling near the capacity of our little Utes, so I'd like to avoid wheel adapters and just swap out the hubs to ones with the 5x4.5 bolt pattern.

I'm wondering what it would take. If there are any bolt-on assemblies from other models, or if I'd have to swap out significant portions of the drive train from an STi like I've heard, or what?

Any info would be fantastic, thanks!
