hey thanks for the question... i can really only vaguely answer it however. i do know that b/t OEM & HFP; HFP is definitely the stiffer & firmer setup. OEM is stiffer than the REGULAR Civic (FG1/FA1 here stateside) but still a lil soft for my taste which is why i chose Honda warrantied & proven/tested HFP setup.
sorry i couldnt be of more specific help but that's what i got for ya.
Thanks buddy. short answer but spot on.
dont mind me asking the next question, under the HFP (which i ventured in colleaguehill honda website) there are 3 different part nos for Si 2 dr and 4 dr and normal civic. in your knowledge, can the Si (4 Dr) HFP fit the normal civic 4 dr?
