the 35 is the closest fit but as we all know they are multi-fit batteries, using top post and side posts.. so you get designations like 35/75 etc
any one of the optimas will fit, but the 35 is good
also for a FMIC fitment, get the 51R yellow top. It is shaped VERY narrow, and is intended to fit the honda civic, but will allow for fmic piping on the s13
