i know there is something that came wrong from the factorty that causes my tires to wear un even. Can anyone tell me what needs to be replaced to prevent this from happening??

 

get an alignment

 

ive already gotten an alignment and it didnt help. i even went and bought the spc camber kit to see if that would help and nothing.

 

See if there's updated P/N's for the front, rear, suspension parts. I know Honda changed the rear arms on the 09+ to correct camber problems, so possibly they updated the 07-08 sedan P/N's with the updated parts.

Edit: There is a TSB regarding this problem

The problem is the excessive negative camber due to the shortened rear upper arm from the factory. The TSB states that the rear upper arm be replaced with the newer, updated upper arm with the "c" stamp that is a tad longer to get camber closer to zero. If you have a camber kit, which is essentially the same thing or better, and its still a problem then I don't know what you can do. Instead of following the factory specs on the alignment machine, tell the technician to get the camber and toe as close to zero as possible.

 

def need an alignment, your camber might not be off but your toe probably is

 

let's not forget back shocks chew up tires but allowing excessive oscillations. not saying it's more likely than rear arms (considering there is a TSB about that) but it's also an option
