Mine (lux/nav/ML) weighed 3620 on a certified scale at the drag strip. That's 205 lbs MORE than my Supra. Supras do well with 315s all around for road courses.

 

I've been hearing from around the block that Eibach actually makes the springs for F-Sport division of Lexus. Anyone confirm/deny?

Just like how I've heard that F-Sport outsources their exhaust for 2IS to HKS.

Truth. F-Sport springs are Eibach Pro-kit and F-Sport shocks are Bilstein.
