Re: enquiries on muffler n upgrading of rim size.
my 2 $0.002...
read that bigger rims are better (stable?) at higher speeds but not good at 0-100 kmph timings as compared with smaller rims.
if u like to race traffic light to traffic light.. then no point upsizing rims...stick to stock size...
and use lighter rims.
if u drive at high speed (i.e. on race tracks etc), bigger rims help....
of coz lighter is better...
not too sure if size of rims affects fuel consumption if the weight remains the same...
if looks matter more than both the points above, then the bigger the better...heavy or light not much difference as it is the visual impact that kills...and u probably want to drive slow enuf for people to notice : )
am not sure why the muffler should increase fuel consumption though....
have a gr8 day ahead!
