Im sorry. i dont understand what is the fact you going to relate what you commented and the post you linked.
by looking at the quoted post,
if you meant to say performance upgrade is not necessary for road use, i think there is no limitation on people what mods you do with your own ride. irrespective of gaining performance on the street or on race track. why we see conversions lancers to evos, impressa to WRX/STI, HB15 to VZR, Soluna to GT Turbo, Mini to DOHC Vtec. Not only Hondas.
