I personally like the feel of the stock steering wheel .. sat in it and immediately it Felt right and good.
It looks decent too - plenty of grip .. the only annoying part is the silver plastic part at the bottom middle ..
But yeah, must would be I/H/E/Tune in my opinion :/
light weight rim 17/18"s with stickier tires.
rest seems like nice cosmetic options for more flashiness
edit - no headers .. that's too bad >.<
edit 2 - look into aftermarket seats that have 86 stitched into them - that would be sexxxy - I'd debate the package just for these (if I didn't know crap about cars and didn't know you could order them separately later for less)
edit 3 - Oil temp & pressure gauges!! *****
lol Sorry about all these edits - too many fun ideas >.<
