If you are planning on running RPM rod ends then you will have to swap out all the stock ball studs. I believe all the stock ones are 4.7mm I put 4.3mm on my car and even those are a little to tight with the RPM rod ends. I snapped them on and off a few times to loosen them up, and I've been driving the car with them so they are finally to the point that they don't bind anymore.

Just giving you a heads up that the RPM's are not a direct replacement.
