Curiosity:
Are the part numbers identical for the IS350 Upper control arm when looking at build packages?
Example: sport package vs Luxury package vs stock?
How about comparing to a non-AWD 250? Or the IS-F?

What I'm looking for here is whether Lexus offered different control arms to alter camber/caster settings depending upon the factory build of the car.

I'm guessing the F comes factory lowered over the standard models? So there should be a different part number there, but maybe not for the rest?

Sorry, the question just popped into my mind
Appreciate anyone that can take time to look into it.

Upper control arms are the same for all models. Part number is 48610‑59065 for all models.

Lower front control arms are also the same for all IS models w/o AWD.

Front suspension crossmember is identical for IS and GS models except AWD.

Rear suspension crossmember is identical for IS-F, IS350, GS350, GS430, GS460, an GS450h.

Some parts are different, but not the big ones.

Wow...
Wasnt expecting that (thought Id find a secret camber change for our cars...).
Thanks for taking the time to dig into it for me/us
