Stock Camber Adjustment on 03 Gs430

Having some Leon Hardiritt's built for my GS. They are rather Mild in the rear 19x10 +27. Not wanting to shave or roll my rear quarters and unfortunately my Stance coil overs don't have camber adjustment. I've read that the stock lower control arm has a bolt that can adjust negative camber up to -5 which should be plenty for my needs. Is this true?

For anyone that finds this thread. Here is the answer. [url]http://www.clublexus.com/forums/suspension-and-brakes/659889-rear-camber-adj-bolt-location.html[/url]
Although it doesn't allow a ton of adjustment its just enough for those running milder fitment.
