hey honda-tech. though you guys could help me out with an issue i have.

just bought a set of 16" rota slipstreams for my EM1. tires have about 1 summers left of tread, nitto gen 205-40-16, i put them on last night and didn't really like how small the rims seemed after putting them in front. my question is: what tire rize should i get for the rims and the car, 205/55/16? the car has skunk2 lowering springs on it already

also what lug nuts would you recomend with these rims. i was looking into extended closed ones

any help would be appreciated
