I've got a 2015 GS350 F-sport RWD that I'll be setting up on Airrex/Accuair in the next few months and I'm currently sourcing suspension components to ensure camber and toe are set properly. I've done a ton of research and see that Megan, SPC, Figs and MAX all make packages for our cars...but I just wanted to double check what is actually needed?

Here's what I'm seeing for the rear:
- Upper/Lower control arms
- Upper/Lower traction rods
- Toe rods

Here's what I'm seeing for the front:
- Upper control arms
- Front lower arm rear mounts - swap to polyurethane - PURCHASED

I see most people are definitely running the front lower arm rear mounts, rear upper/lower control arms and toe rods...but are the aftermarket UCA's and rear traction rods going to make a huge difference? I'm not worried about camber, but I want to make sure toe is as close to perfect as possible. I'll be running 20x9.5 up front and 20x10.5 rear. Any input from those who are running a current setup would be much appreciated.

 

I just replaced all the arms just so we could dial everything perfect as much as we could. also make sure you tq everything to oem spec if not its gonna make alot of unwanted noises. also check your airfittings for the bags and what not before installing because it will be a ***** to check and tighten once you install it, sometimes impossible without uninstalling it. loctite is your friend for the bolts that hold brackets for bags, wouldn't want those to come out unintentionally. let me know if you need more info I feel I hit a few good points

also I am running 20x9.5 and 20x10.5 on my setup shaved rear and pulled/rolled front

 

Megan Racing arms and SPC lower rear control arms are a popular combo. Just to dial things in for when you're driving or parked..

Thanks for the great feedback thekhmer. I appreciate the guidance. Did you have a preference on which arms to use?

 

I suggest you just check your alignment on a rack after lowering. My IS300 toe and camber was still in spec after lowering. If you have aggresive wheels then you might want to install the rear camber kit while the springs out.
