The Front Brake Upgrade provides a firmer pedal feel and improved fade resistance in repeated severe-duty use. The Brake Upgrade features six-piston fixed calipers and drilled cast-iron 355-mm diameter rotors with a patented internal-fin design mounted on anodized aluminum hubs. Braided stainless-steel brake lines and low-dust performance brake pads are included, and the upgrade can be used with stock or the F-Sport Rear Brake Upgrade.
Similar in construction to the F-Sport Front Brake Upgrade, the Rear Brake Upgrade uses four-piston fixed calipers and drilled cast-iron 345-mm diameter rotors. Braided stainless-steel brake lines and low-dust performance brake pads are also included. The Rear Brake Upgrade may only be used in conjunction with F-Sport Front Brake Upgrade.
This system features all stainless-steel construction with fully polished mufflers and double-wall exhaust tips. In addition to an outstanding appearance, it delivers a powerful, sport-tuned exhaust sound and does not affect emissions compliance and complies with established sound-level standards.
This low-restriction intake and filter assembly is fully compatible with stock engine controls and is emission legal in all 50 states.
Constructed from real carbon fibers, this light-weight, durable engine cover provides a high-tech appearance under the hood. This is a direct replacement for the original cover and is available for both IS 250 and IS 350.
The F-Sport Performance Clutch Set, available for the IS 250 equipped with the manual transmission, increases clamping force approximately 16 percent to handle higher torque capacity and provide improved feel.
Engineered and machined from billet aluminum, the F-Sport Quick Shifter for the manual-transmission equipped IS 250 decreases shift throw by approximately 35 percent for quicker and more positive shifting.
Developed in cooperation with Bilstein® and available exclusively through the F-Sport Performance Accessory program, this shock-absorber set offers sport-tuned suspension dampening without sacrificing ride quality.
This feature lowers the vehicle approximately one inch in the front and rear for a more aggressive appearance and a lower center of gravity. The spring set is engineered to deliver lowered ride height without bottoming out or creating a harsh ride. The set is available for all IS models and can be used with either the stock or F-Sport Shock Absorber Set.
This set includes larger diameter replacement front-and-rear sway bars that offer reduced body roll and flatter cornering. Urethane-mounting brushings are also included to replace the original rubber brushings. The IS 250 RWD and IS 350 set includes both front and rear sway bars, while the IS 250 AWD includes a rear sway bar.
To improve chassis stiffness under aggressive driving conditions and provide a more responsive feel during cornering, the F-Sport Rear Chassis Member Brace joins key rear-chassis and suspension mounting points through this tubular steel brace.
