Default XE20 Lexus IS-F?

Lexus still hasn't decided to give us our precious IS-F, so I decided to do the deed for them.
NOTE: This is still a work in progress. This is very, very sloppy and does not reflect the final product (if that ever comes). Remember, it is just the imagination of a hung-over engineering student, so PLEASE don't kill me.

Here goes nothing:

​​​​​​Lexus IS-F (XE20)

Engine: 2GR-FSE, 3.7L

Power: 500 HP (372.85 KW), 429 LB-FT

Fuel Injection: Direct + Port Fuel Injection (D-4S Twin Injection)

Weight Distribution: 55-45 (Front-Rear)

Engine Specifications:

High Lift Camshafts with Variable Valve Timing (VVT-i); activation >5,000 RPM

Lightened Flywheel (2 LBS lighter)

Braking Distance:

60-0 MPH: 120.5 FT

Increased Chassis Reinforcement via Conspicuous Roll Bars tucked within Dashboard

Lighter Weight resultant of Removal of:

Spare Wheel, Tool Kit, ABS system

Monotube Gas-Filled Shock Absorbers and Ball-Jointed Stabilizer Bars

Vertical G-System

Torque Vectoring Differential with Viscous Coupling; 35-65 Torque Split (Front-Rear)

Front and Rear Coil-Spring Independent Suspension

AA60E Six-Speed Automatic Transmission (Aisin AW)

19x9-inch Front and 19x10-inch Rear Wheels, 255/35R19 Front and 275/35R19 Rear

QUICK NOTE: Lexus does not like to tinker with the engine displacements too much, so the engine displacement would most likely remain a 3.5L.

This thread doesn't even make sense when there already is an XE20 IS-F, the one and only. The only way that car would've worked was to be introduced in early 2015 up to early 2017. Like BMW did with the E46, they felt it necessary to sit out a generation and not produce a XE30 IS-F, in having the coupe XC10 RC-F take its place. That is how the 330i ZHP came to be, as no M3 sedan was made between 1998 and 2007. Only E46 coupe and cabrio.
