Description: The SB5-HDR6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. Precision cover stampings provide rigidity and consistency. ACT's 6-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 6-pad rigid race disc, engagement is harsher, but shifting is faster. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat.

Description: Experience a light to moderate pedal effort with aggressive engagement and increased gear rattle. The kit offers a moderate friction life, extended by ACT's exclusive diaphragm design, although the rigid design may increase spline wear. Carefully engineered, precisely assembled, and accurately balanced, using select ceramic friction materials for high heat tolerance and maximum performance. Recommended for race use only, the SB5-HDR6 kit undergoes 100% clamp load testing and dynamic computer balancing for smooth high RPM reliability.

Vehicle Fitment: Various models of Subaru Legacy GT, Subaru Outback XT, Saab 9-2X Aero, Subaru Baja Turbo, Subaru Forester XT Limited, Subaru Impreza WRX, Subaru Impreza WRX Limited, Subaru Impreza WRX TR, Subaru Legacy GT spec.B, Subaru WRX, and Subaru WRX Sport-tech from 2005 to 2018, including select JDM variants.

Good chair, Hensley is more comfortable
Color: Grey, Color: Grey
Received chair in a large box and assembly was easy. Instructions call for 2-person assembly but I set out to do as much as I could by myself until someone else was available. No tools needed other than the Allen wrench provided. I assembled the chair in under an hour by myself. The 2 person portion of the assembly was for attaching the seat to the wheel assembly but I managed to attach it myself with some careful maneuvering. The chair is nice and comfortable enough, but I was spoiled by the comfort of trying a different Serta model (Hensley, now discontinued) ina store. I couldn't find that model anywhere else and the floor model was SOOOO comfortable with its Serta Smart Layers. I was hoping Bryce would be a close second. After trying Bryce for a few days, I'd say its a distant third. If I never met Hensley, Bryce might have a higher rating. Update: based on other reviews, I made covers for the armrests to prevent wear and peeling of the padding cover.

Comfort and Support
Color: Grey
If you're looking for an office chair with comfort and support in mind, then this is one you should consider. Item delivered on time as stated when purchased. Assembly instructions were quite clear, just make sure all parts are accounted for when opening box. Pay attention to the supplied screw sizing during assembly per the instructions. The supplied hex key, if used, will get the assembly job done, but would recommend using a cordless drill with clutch and appropriate sized hex bit for faster and less fatiguing hand work. Just be sure to start screws by hand first to make sure they start threading into the openings so you won't cross thread the screws. Once assembled, set the chair adjustments to your liking and enjoy a very nice looking, comfortable, and supportive office chair. I especially like the lumbar support built into this product. One last note, if you are going to use this product on hard surfaced floors it is recommended that you purchase soft office chair wheels (sold here on Amazon) because the wheels supplied are hard plastic and will scratch or mar hard flooring.
