Coilovers are the best option as they offer the best of both worlds.
Megan racing EZ street's are inexpensive at 700ish a set.
As for wheels it kinda depends on how much you want to modify your car.
I run 18x9.5 all around but not only do I have a hub swap but I run very heavily clearanced wheel wells.
Usually what's ideal is 17x8 +30 or 17x9 +35 with a 235/40 all around.
The issue will be that the back will want more offset while the fromt is perfect so your options are to run staggered wheels, run a spacer, or buy wheels with two offsets.
It's far easier to find wheels for 5x114.3 so see the hub swap thread.
