2004-2021 Subaru WRX STI ACT Heavy Duty Performance Street Disc Clutch Kit

SB10-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. ACT Heavy Duty pressure plates use 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.

ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance street discs are the most popular disc purchased. They feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. Quiet operation with increased strength and reliability.

Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction will provide years of service.

Perfect everyday Watch
Color: Grey, Color: Grey
Super happy with this watch. It looks really clean and goes with pretty much anything dress it up or wear it casual. The blue face is fire in person and catches the light really nicely. Feels solid on the wrist, not too heavy, and the quality is definitely there. I’ve been wearing it almost every day and it still looks brand new. For the price, you really can’t beat it. Great everyday watch that looks way more expensive than it is. Would 100% buy again

Stylish and inexpensive
Color: Grey
Great watch. Came in quickly from seller. Got it sized at a local shop. It’s a pretty stylish watch for the price point. I don’t have big wrists but I still think the face could be a little bigger. But it’s pretty sleek and I’m happy

Value for money: Value for money is certainly great than with many other Swiss made watches. Accuracy: very good: -4 to +5 seconds per month.

Swiss Quality from a good brand
Color: Grey
This is my 4th Tissot watch. I only have a few quibbles. The band adjusts by removing wide or narrow pieces, not by adjusting with pins with a range of holes. I prefer that way to adjust a metal band. The color blue of the dial is darker in real life than the picture. I also wish the day indicator was a little larger (or my eyes were younger).
