Description: Upgrade your vehicle's clutch system with the FM13-HDR6 kit from ACT, featuring their most popular Heavy Duty pressure plate paired with a high-performance 6-pad rigid race disc. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for unparalleled durability. Precision cover stampings ensure rigidity and consistency for reliable performance.

The kit includes ACT's 6-pad rigid race disc, made with high-quality ceramic friction materials and a heat-treated chrome-moly hub for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service, though engagement may be harsher. This kit is recommended for larger clutch sizes to absorb more heat.

Look and feel nice. My feet are size 8.5 men’s USA and they are reasonably snug. The will seems a little better than cotton.

My new favorite socks!
Color: White, Size: Medium
As someone that struggles with cold hands and feet, I started experimenting with using merino wool socks over my usual cotton and polyester blend socks. I am very pleased to report that these merino wool socks are very comfortable and warm. They have a secure and comfortable fit--ideal for casual everyday use. These socks perform well as athletic socks for winter soccer, and will slowly take over my sock drawer! These socks have a good thickness to them and feel durable for normal wear. The elastic portion of the sock stretches to accommodate wider ankles (like mine) and does not feel like it will lose elasticity quickly. Very fair value for the cost in my book.

Great product
Color: Black, Size: Medium
Super soft and fits like a sock should. I wash in a lingerie bag on gentle cycle and hang dry due to fabric type. My feet don't get sweaty which is why I have chosen merino wool products as all of my base layers (socks, underwear, etc)

Lightweight and Comfortable, but very thin
Color: Black, Size: Large
I used the Lapulas Merino Wool Quarter Socks for Men on a Europe trip where I was walking pretty much all day, and overall they performed well. The biggest thing to know right away is that they are very thin. If you’re expecting thick, cushioned socks, these are not that. They feel more like a lightweight layer rather than something padded. That said, the thinness actually worked in my favor for travel. Even after long days of walking, my feet didn’t feel overly sweaty or damp. They seem to handle moisture pretty well, and I didn’t get that uncomfortable “wet sock” feeling, which is a big plus when you’re constantly on the move. They’re also surprisingly decent at regulating temperature. They’re not thick, but they still help keep your feet warm when it’s a bit cold, while staying breathable enough during the day. It’s more of a balanced, all-day comfort rather than heavy insulation. One thing I noticed is that they stretch out a bit after the first use. They’re snug at first, but after wearing them for a day, they loosen slightly. It’s not terrible, but it’s noticeable, especially since they’re already thin. Also, proper care really matters with these. Since they’re merino wool and lightweight, I’d recommend being careful with washing and drying—gentle wash and air drying is probably the best way to maintain the shape and quality. Throwing them in a regular hot wash/dry cycle will likely wear them out faster or affect the fit. Because they’re thin, they fit nicely inside shoes without feeling tight or bulky, which I appreciated when wearing sneakers for long periods. Pros: -Lightweight and comfortable for all-day walking -Good moisture control, feet don’t feel damp -Breathable and not too hot -Helps keep feet warm despite being thin -Easy to pack for travel Cons: -Very thin, not much cushioning -Slightly loosens after first use -Requires careful washing and drying

Too stretchy for my preference
Color: Black, Size: Large
The socks seem to be high quality, but they are too stretchy for my liking. They feel like "compression" socks, and become too thin and stretched when worn (yes I bought the correct size). Even though they have less Spandex than my preferred wool socks (e which are no longer available), they are much stretchier.
