as we know that different types of tyres got different function or purpose like some is for the use of track, some for comfort driving and others..
I m thinking of getting tyres with sporty performance..but does it...
yesterday i just install my ground cable....
first is that my car is old..
so originally.. if open lights.. the rpm will drop a bit..
but then.. after i install ground cable, also same.. :(
