Is300 Rebuilt Suspension (Coilovers and Bushings Replaced)
Info:
2003 Lexus is300 Sport Design
Automatic 5 Speed (E-Shift)
Thundercloud Metalic
186,500 Miles
Tampa, FL
History:
I purchased the car in January of 2015 with 154k on the clock from Lexus of Clearwater. Car was in very good shape but over the years as the miles added up I came to the conclusion that rebuilding the worn suspension would be a major improvement for the car. Previous replacements prior to this thread include Drilled/Slotted rotors as well as Front Lower Ball Joints. I Decided to go with Fortune Auto 500 series (6th gen) coilovers in which I purchased on Black Friday last year. Also purchased some Superpro LCA #1 (Lateral) and LCA #2 (Caster) bushings as well as Front and Rear Sway Bar Bushings from FIGS Engineering. In addition I purchased one of his Rear Lower Control Arm Spherical Bearings as well his Solid Steering Rack Bushings to add for extra grip/lock. Car handles much better with the aftermarket components and an alignment. Running the coilovers with the standard preload from the factory and the lowest of the 24 way dampening adjustments. Anyways, here are some pics I took during the process.

I have a very similar set of parts as you.
I'm surprised you can still use the stock rear lower control arms.
I bought the figs mega rear arms but they are much heavier than stock.
I had to get them for the rear tires to get into correct alignment for even tire wear although I'm not that low.
I have it at fortune auto gen 6, front 5 clicks back from full stiff and rear 9 clicks back from full stiff.
Rides nice but still firm with poly bushings front and back. The rear is a bit swiggly that's why I softened it up
