Do is-f's.......
Do is-f's share the same suspension as the is350?
if i were to buy a set of coilovers for the IS350 would the bolt up to the control arms and the shock tower mounts with out modification?

Per Lexus:
"Sports Car Dynamics The 2008 IS F is based on the robust IS platform, which was engineered from the start to allow a high dynamic envelope. The stiff body structure and the rear subframe are connected through several reinforcements.
Although using the basic double-wishbone front suspension and multi-link rear suspension configurations of the IS platform, the IS F benefits from a multitude of track-proven modifications. The IS F sits an inch lower on its suspension than the standard IS models, helping to lower the center of gravity for quicker handling response. Like other IS models, the IS F employs high-strength steel suspension components for the optimal combination of rigidity and weight.
Spring and damper rates are increased, and larger-diameter stabilizer bars are used. The rear-suspension control arms are specific to the IS F to optimize geometry for the 19-inch wheels. In addition, the monotube shock absorbers use a larger-diameter piston rod. As on other IS models, the sophisticated shock-absorber design utilizes multi-leaf linear control valves to help improve damping force, and rebound springs offer improved body control without degrading ride comfort.
Suspension bushings have been specially tuned for better feel, and the subframe suspension mounts are stiffer than on other IS models to help reduce sway and ensure control under acceleration and braking. The engine mounts are also stiffer for a more direct feel. Special jounce stoppers added to both the front and rear suspension come into play early in the compression stroke to help reduce the roll angle when cornering and to reduce dive when braking. High-rigidity hub unit bearings are engineered for rigorous, high g-force track driving."

That's a logical assumption, but its not necessarily true. Remember that the control arms are different between the two models, and there's no guarantee that the mounting points are the same.
