^You can, I ran that setup for a while.

 

the negative camber lets the car carve into the corners. removing the camber would technically reduce performance but you probably would not notice it in day to day driving. there really is no major difference between the camber kits except price and brand name. they all do the same thing

also. if tire wear is your biggest concern, get tires with the highest UTQG, i.e. around 500. OEM tires, and the sterotypical "high performance tires" have really low ratings around 150-200. They stick more, but they also wear out much quicker. getting a tire with high UTQG makes a big difference

also sounds like your rear tires were overinflated. "center wear" is not consistent with neg camber wear (its suggestive of overinflated tires). inner shoulder wear is suggestive of neg camber wear.

 

so if i decided to go with one tire what should it be.....

245/40/19
or
245/35/19

 

Do you check the sheets to see what you're specs are after they align it? But overall 24k a year is REALLY good, i remember when i got like 4k on a set of rears... there went $400

 

That's so incorrect it hurts my head to read it. Talking about front kits, the only 2 available on the market that will give you any significant positive camber adjustment are the SPC and the SPL. The rest out there don't have the capability. For the rears, the Ichibas are well known for bushing failure and mine have suffered the same fate. Long story short all camber kits are NOT the same so if you go that route OP please do your research before you buy anything.

 

Thx Blue Dream.... ive been researching up the wazooo....

i think im going to skip the $500 camber kit and instead of buying the directional Nankangs again im going to go with the Conti's DWS and then rotate them like every oil change and get a Dealership alingment since im on the 350z H's.....

anyone think this is an ok plan or have any other suggestions?
also, would now be an ok time to add spacers?

 

sorry, I thought we were only talking about the difference between SPC and SPL

 

Depending on which ones you get you can add spacers at any time. If you get the ones with the built-in studs, its as easy as changing a tire.
