i upgraded from 14" stockies to 16" roh adrenalins on my civic si
expect take off to be effected... but then again expect top end control to be drastically improved.. i did 200km/h on the 14" and it didn't feel too good o_0 but now over 160km/h and it still feels very firm
take off is slower naturally due to the weight of the rims but i rekon if u get it right (i.e ride the fuk outta ur clutch) + the extra rubber you can do good ones.. just a bit slower than the stockies
in the end dude its upto u...
and i think wen jon sed "When i "up" graded to stock VTiR integra alloys (15"), the increased torque and performance of my stock car was seriously incredible." that its a bit overated.. i went up 2 inches bigger and it wasn't that bad...
if people say that its a "performance downgrade" if you get bigger rims then they are wrong (to an extent :D ) if you got soft suspension like i do and small wheels then expect it to feel floaty at high speeds.. also if you take corners too hard with 14" it will slide easily but with 16" it won't as much... simple?
in the end.. 16" is where its at cz seriously how many times do u drag/highspeed test/DRIFT? want your car to look nice? then get 16"s if you want performance then get lighweight 16"s.. 14/15" are shit house..
want proof?
