Description: The MS1-XTR4 kit features an Xtreme pressure plate designed for the most demanding drivers. ACT Xtreme pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a comprehensive four-stage heat-treating process for unparalleled performance. Precision cover stampings ensure rigidity and consistency in ACT pressure plates. The 4-pad rigid race discs are crafted with high-quality ceramic friction materials, with the chrome-moly hub heat-treated for enhanced strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, anticipate harsher engagement but faster shifts. This disc configuration is well-suited for the smaller disc sizes in smaller engines.

Read This In One Sitting…..
Format: Hardcover
Not pregnant yet, but this book was the perfect balance of information and real-life story. It was so relatable and reassuring—I suddenly didn’t feel crazy for all the hours of baby research I’ve been doing. I never felt pressured, just encouraged and entertained while learning so much. Such a refreshing read, you won’t regret getting this one!

Great Buy for First-Time-Mama's
Format: Hardcover
This is my first pregnancy, and I'm very happy I purchased this book. Meghan Trainor will make you laugh and she gets very real with you—it was almost as if I was hanging out with an old friend when I sat down to read. It's a mix of a memoir, a diary, and advice from experts including her personal trainer and her OB/GYN—including exercises by trimester and recipes. She also recommends some products without being sales-y. If you're a first-time-mom (or even if you're not), this is a great buy that's not like other pregnancy books (those can sometimes be information overload in my opinion). This would also be a great gift for a newly pregnant friend. You don't have to be a Meghan Trainor fan to enjoy this book. Book Highlights/Helpful Thoughts - One of my favorite phrases was "influencers are great, but they make pregnancy and labor an aesthetic, and girl, pregnancy is not an aesthetic, it's rough!" - Meghan wanted to give birth vaginally, but due to complications, she had to have a schedule C-Section and she talks about that experience extensively is a way that was helpful. I'm personally doing everything I can to have a natural vaginal birth, but life sometimes has other plans. It was helpful reading her take instead of reading the Reddit horror stories. I now know what to expect in a non-traumatizing way if I were to need a C-section. - Meghan was pregnant during the height of the Covid Pandemic in 2020—so her experiences are based on that. I say this, because she talks a lot about how her husband could not join in at any of her ultrasound appointments and her labor team was limited due to the restrictions. Thankfully appointments are no longer like that.
