Well, I guess more clearly understanding what "sucks" means would help us know where to start. In stock form, the factory disc/drum set up should be plenty capable for casual driving, so a frame of reference form ou about another vehicle that you consider good can give us that reference.
So, are the just kind of soft, not responsive enough, subject to fade, never seem to grip well? The more specific you can be, the better we can be at suggesting improvements.
The same with steering; is the response slow, does it have excess play, or is it just the generally malised factory over assist?
