well thats usually a RWD trait, but on fwd i imagine it would be strictly for handling or maybe just a 'look'. I know the newer GP GXPs have wider rears.

really the newer GP have wider rears? Anyways yes its usually a rear wheel drive thing for more tracking on the drive wheels. The stance looks a little meaner too. I see 350z constantly use this method and it looks awesome.

but rotating is a bitch if you didn't guess that yet.

John, you're mistaken, I'm afraid

The new GP GXP uses wider FRONTS and skinner rears.

They do that to reduce understeer but the suspension components are tuned for that.

Get the same size tires and wheels all the way around

the only reason why some cars do wider in the back is cuz its a RWD car and it helps handling on RWD cars

i dont know much about what tires will fit on a lowered 2000+ but i do know that someone did put 255x?x20" tires on there 96 SE, but he had to put air bags in the rear springs to keep them from rubbing

i would think the 2000+ bonnies have a little more room (at stock height) but lowered... :? im not to sure

No one ever put wider tires on the rear of a FWD car that knew what they were doing, unless it was solely to get more grip out back.

99.9% of the time, the fronts need more traction on a FWD car anywho. But too wide can be bad for handling depending on the suspension geometry.
