Howdy,
OK, I want to hear how caster works differently rear compared to
front..... and if your rear steer steers with a wider track, so what? we
are not making corners here(sorry, I mean on the Salt), as to Davenports'
lakester, isn't that one a rear drive car? this will make a big
difference...So far we've been discussing FWD rear steer, something that
has weight forwards which will cause the rest of the vehicle to follow a
lot easier than the rear drive weighted vehicles that spin easy . I grant
it is not a "natural" feeling driving a rear steer, but it would be, if you
had not driven anything else......
