First I'll start, my car is a dc2 gsr. Here are the details of my setup

Suspension: Function&Form Type-1
Wheel specs: Enkei 92 mesh reps; 15x7 +20; 195/50/15 all around.

The front wheels are flushed perfectly and tuck a bit of tire exactly how I like it. And could still go lower if I wanted to. The rear's of course poke out a bit, but I know it's fixable with some rear cambering. I've already rolled the fender's as much as I could and it still rubs a lot. I want to tuck the rear tires a bit more. Any suggestions or tips? Appreciate everyones responses. Here's the car and wheels in reference. Thanks for looking!

 

buy rear camber arms that have a negative camber setting to them

 

Sounds good, any recommendation on brands? And/or how much negative camber setting should I be look for? thanks
