Description: The ZX4-HDR4 kit by ACT features their renowned Heavy Duty pressure plate coupled with a 4-pad rigid race disc. Utilizing an exclusive diaphragm design, ACT's Heavy Duty pressure plates enhance clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a rigorous four-stage, heat-treating process to ensure unparalleled performance. Precision cover stampings contribute to the rigidity and consistency of ACT pressure plates.

The 4-pad rigid race discs are crafted with high-quality ceramic friction materials and feature a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design enables quicker shifts and ensures smooth, trouble-free service. While engagement with the 4-pad rigid race disc is harsher, shifting is faster. This disc is particularly well-suited for smaller disc sizes in smaller engines.

Key Characteristics:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design; rigid design may increase spline wear.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, utilizing select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for race use only, ideal for drivers seeking high-performance clutch systems optimized for competitive racing environments.

ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Vehicle Fitment: Compatible with various Mazda models, including the 2006-2013 Mazda 3 Mazdaspeed and the 2006-2007 Mazda 6 Mazdaspeed equipped with the 2.3 L4 GAS FI 2260cc | DOHC engine.

Excellent sound and function
Set name: 5.1 Receiver
We're very pleased with this unit. We use a 3.1 system in our TV area, stereo plus center channel and subwoofer. It's nice that this unit supports that. We get very nice imaging from this, and don't really miss the surround speakers. **We had to replace the old HDMI cables with new ones that could handle the larger bandwidth of 4K. If you're cables are 5-10 years old like ours, newer cables are required to carry a modern video signal. We like the Yamaha sound, and are able to EQ it easily to sound right for the room. I've used several receivers over the years of various brands. Yamaha consistently delivers good sound and reliable product. I've never had a Yamaha product fail and fewer than 15 years. There are other units out there with more gadgets and gizmos, bills and whistles, not to mention smoke and mirrors. We want a good sounding reliable unit that plays nice with all of our AV sources and TVs. If that's what you're looking for, look no further than this unit right here. If you get a good price on this, it's unbeatable. Sony, Onkyo, Denon, Marantz, etc. - they all make good units with signature sounds. If you aren't familiar with them, and If you can't listen to a bunch of stuff, buy this with confidence. Here's an unsolicited recommendation: high quality speakers will do more to improve your listening experience than any receiver. If you're looking for an upgrade, start with your front speakers.

Love my Yamahas
Set name: 5.1 Receiver
RX 385 replaces my much-loved 10 year old RX 375, which I inadvertently fried while experimenting. The 385 has some newer features, including bluetooth. The old model and this both use the handy YPAO function to tune the audio speakers' depth of field to the listening environment. It's a broadcast mic that you just plug into the front of the receiver for a few seconds to determine each speakers' distance from viewer. Kind of a sonic echo measurement of seating to speaker. It's a foolproof, remarkably clever, timesaving gizmo. The YPAO mic is absolutely included with this unit, looks like a little plastic cone. Also important to me, Yamaha has replaced the old spring clips for rear/side speakers, which are now the better screw and cap posts, as they have always been for the two front speakers. I recommend rocketfish HDMI 4k/8k cables to connect this receiver to your tv and to whatever other components you want, such as a bluray. Sound quality is excellent if your speakers are good. (I like KEFs.) Of course you may prefer wireless speakers, but I'm already committed to wired ones. I used rocktfish banana plugs to connect my speaker wires to the RX 385 receiver's speaker posts. Neat and clean. With a choice of 2 front, 2 rear, 1 center speaker, plus one coaxial plug in for a subwoofer, your movies and programs are going to sound far more detailed and staged than you'd get from the tv or a sound bar. It's a more immersive and compelling experience. (I use only 2 fronts and 2 rears and don't feel I'm missing anything.) Yamaha receivers and other components are my favorites: relatively inexpensive, well designed, solidly built, and not fussy to install. If you find yourself in a pickle there are a couple of helpful youtube videos. I find with the RX385 again that Yamaha does not disappoint me.

Outstand Product!! 😉
Color: 14AWG-1 Lead
This is my second (at least) Nilight wiring harness. I wanted to re-do the lights on my Rhino 660. This makes it SO EASY! 👍🏼😉 And a hell-of-a-deal!! All I had to get was a "reamer" drill bit to enlarge the switch holes on my dash. Run the wire, attach the ends to the light, switch & power source, all done. I did add "shrink tubing" to my connections to add an extra layer of insulation/weatherproofing. 👍🏼

Definitely a good buy very professional craftsmanship
Color: 14AWG-1 Lead
As a retired master technician for Honda and all makes and models of automobiles this harness is a cut above the others is put together immaculately and anyone that can put a wire through the firewall I purchased my light bar to harbor freight 22 in great lighting but their harness kit was 56 bucks I paid under 24 this and it looked identical except the switch on this is actually much more appealing cosmetically and works well functionally just had to drill a hole in one of the blanks 4 switches in my truck made it fit perfect and has worked flawlessly since I put it in a couple weeks agodefinitely do your homework sometimes I find great deals at harbor freight that nobody can touch on Amazon but then other times vice versa Amazon has a great product at a great price compared to harbor freight in other retailers
