one of my friend also driving proton persona,using 17 sport rim,he claim is lightweight.After he change the sport rim,we tested on pick up and corner.During the race,pick up,he lose by min 1 car space,then at cornering,his car also not that stable only,and the problem is,the wheel arch is rubbing the tyre,got krak krak sound,so means if you want to change to 17 inch,you have to hit the wheel arch at behind there a bit + since the tyre profile is lower,good luck my friend with the holes and bad road condition in malaysia,now my friend planning to change to adjustable sport suspension to match the look and hope the tyre wont rub the tyre anymore,in my opinion = 17 inch + low profile tyre ( 215/45/17 ) + adjustable suspension = die very fast and not comfortable to sit and drive at all,if you really want,i think use 16 inch with 205/50/16 is ok,b4 i am using this size sport rim and tyre,also i face the same problem with the tyre rubbing wheeel arch when 1 or 2 person sitting behind,also quite irritating and felt heavy too,hehe.
As for hot bits header and k & n filter,this both item for me,i think not necessary to use brand from hot bits and k & n,for the header,you can get it outside much more cheaper if you are on tight budget,the filter also even if you changed to k & n,yes,it give u good performance and save petrol,but other performance filter also will give you the same effect and much more cheaper,the main reason even after you change the air filter,also won't feel much because the main problem is the air sucking place.The air from outside flow in to our air filter is not enough,the bonnet space for the air to go through is too small and i doubt air can travel in from outside,so what i am doing now is,i use other performance brand air filter,but i add a cold air intake hose from the sport light hole straight up and connect to the air filter box,the results is you'll definitely have enough cold air sucked frm outside and give u big improvement,for the air filter + cai i only did it for rm 240,u buy 1 k & n filter also around that price,so which 1 u think more worth it?header i have nothing to say,maybe using hotbits is custom made for that car model while other cheaper 1 outside is universal,but diff not much also,wont give u that i am faster than u feel.the important thing is the exhaust setup,if u do it correctly and find a good tuner,sure u will feel satisfied,hope this info helps u my friend.
