is there any RSR I coilover install instructions on here for 2015 Lexus GS350 AWD. Im having a hare time finding out how to adjust the height in the rear correctly for the separated spring struct configuration.

Not sure if you have had any luck on here, but seeing the age of your post, I'm sure you've figured it out by now. I have a set of Megan Racing Coilovers "professionally" installed by a local mod shop. I use air quotes because they had the car for nearly a week total between two visits, I ordered a spacer of sorts through them which helped some but still the same problem. They are claiming the front can be adjusted quite a bit, but that the back is adjusted as high as it will go but I still have rubbing in the rear. Its bad enough to where I cannot have luggage in the trunk or anyone in the back seat. Although they tell me the called Megan tech support to walk them through the entire install, I'm not sure if they quite know what they are doing. I spoke with Megan myself and they tell me these coilovers can be adjusted from about 1" to 3" of drop. The rear seams to be around 2.5" from stock height at the point the shop is telling me is the highest it will go. I do have a 20x10 on the rear which I know can be the cause of some of the problem. Any help you have would be appreciated.

The spring sits on a spring-seat nut that's on a threaded sleeve. You should be able to rotate the spring seat around the sleeve to raise/lower the height. There's usually 2 locking spring-seat nuts that are tightened together to prevent them from rotating during driving.
