I have a 1997 mitsubishi diamante that I am looking to see if there is a way to get some negative camber to the rear wheels so I can tuck my stretch tires into the rear guards

Sedan or wagon?
Different rear setup for them at rear.

It's a sedan

It's going to have a spacer so it's going to unfortunately stick out

Ingalls Engineering make rear camber kits for Magnas. I bought a set from eBay USA. I think it was around $200 delivered for front and rear kits.

Just make sure they are for a USDM Diamante rather than a JDM Diamante as they had different suspension setups. USDM is same as ADM, however JDM is completely different.

Thank you Red Valdez I will look on ebay to see if I can find how many degrees of camber were you able to get with the kit
