034Motorsport's Density Line Upper Control Arm Kits are available as Adjustable or Non-Adjustable Control Arms, and are designed to be performance replacements for all four of the factory front upper control arms. The result is tighter handling and more precise steering response than even brand new factory control arms can offer. In addition, adjustable upper control arms allow optimal alignment for your lowered or track driven vehicle.

The factory front control arms are an integral part of the suspension, but can start wearing out as early as 40,000 miles - especially on enthusiast-owned vehicles which are driven hard on the street or track. As the rubber bushings degrade and ball joints develop play, alignment is compromised and steering becomes less precise. This kit is a drop-in replacement with feature improvements over stock, that will tighten up front-end feel and allow camber adjustment to significantly improve handling.

DENSITY LINE NON-ADJUSTABLE CONTROL ARMS:

034Motorsport's complete Density Line Upper Control Arms are designed to be a performance replacement for all four factory front upper control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Control Arms are engineered to limit unwanted deflection in the suspension, resulting in tighter handling and more precise steering response than even brand-new factory control arms can offer.

DENSITY LINE ADJUSTABLE CONTROL ARMS:

Featuring high-durometer rubber bushings, high-quality ball joints, machined-billet upper adjustable control arms, and Aurora or FK spherical bearings, this kit is engineered to limit unwanted deflection in the suspension. 034Motorsport's Density Line Adjustable Upper Control Arm Kit replaces the fixed factory front upper control arms to allow for precise, independent camber adjustments. Density Line Adjustable Upper Control Arms for the B9/B9.5 platform are available in two versions depending on your specific needs.

INSTALLATION & WARRANTY:

Installation:

  • It is imperative that the suspension be compressed to static ride height before any suspension pivot bushings are tightened, as per the factory installation procedure. If this is not done, the bushings will tear prematurely as the twisting forces on them will be much higher than is intended. 034Motorsport's Limited Warranty on Density Line products does not cover premature failure due to improper installation or use.
  • We highly recommend professional installation for this product.

Overall Excellent - Thorough Review - READ ME
Style: Stereo Receiver, Configuration: Receiver
I'm not an audiophile per se, but I do have elevated listening preferences. I enjoy finding the value in devices, and system configs. So that's the reason I tried this more budget-friendly receiver. Aesthetics: The look is very sleek and modern, which is great but sometimes I miss the nostalgia of more knobs. There is no base/treble knob and most everything is controlled by remote. That's fine I suppose, just be aware. The volume knob is very large and traditional which I love, but is also very stiff and not buttery smooth like you might expect. Perhaps that will break-in. Sound Quality: Wow, this sounds incredible. There is definitely a DSP happening that is noticeably awesome. It's referred to by Sony as Pure Direct. If you want to by-pass this, you can, but you'll hear right away the difference is major. I'm using simple Klipsch bookshelf speakers, and my expectations are surpassed on how much they come to life with bright and rich sound. Definitely a nice pairing for those shopping for speakers along with this unit. Overall the SQ is gonna be tough to beat without spending exponentially more. Remote: The remote is nice, sleek, and has what you need to quickly access. No complaints there. Installation: Takes minutes, super easy. Didn't follow any instructions due to my general confidence hooking up home audio gear. Overall: I highly recommend this one, and I'm picky. Initially, I fully expected to return this receiver, but plan to keep it. The only thing that may change my mind, is if I miss the nostalgia... then I'll have to go vintage. But no way a vintage receiver will sound this good. Props to Sony. Well done :) A+

Nice amplifier for the cost.
Style: Stereo Receiver, Configuration: Receiver
I had been using my Marantz model 22 receiver now for a couple years now with the TV, dvd player, and youtube music from my tablet. I like lots of knots and switches on my audio gear, I'm an engineer. I was getting tired of the seemingly endless up and down to adjust volume and whatever. And my inputs on the Marantz were maxed out. I searched Amazon to see what was available as a possible replacement that had a REMOTE. This Sony caught my eye. Relatively inexpensive, plenty of inputs, and specs I could trust, not a 3x4x5 box offering 220+220 watts of unlimited power! Ordered it and been using it for over a month now. Only 2 knobs, how good could that be? Well, it's remote let's me control everything without getting up. Plenty of output power, 100+100 watts of true RMS power. I didn't plan on using the Bluetooth but I tried it with the tablet, keeping the tablet by me, and it really impressed this old audiophile. I really don't have any negatives about it, even the fm sounds great. It was heavier than expected but not as much as that old Marantz. I even popped the cover. The build quality was what I consider good. I only wish I could find a service manual with the schematic for it.

real time and energy saver, as well as $
Size: 16AWG Wiring Harness-2 Leads
If you have a set of LED lights that didn't come with a harness , you can't beat this for the price. By the time you figure in the cost of the parts ( wire, switch, crimps/connectors, not to mention a relay if you are using one) to hardwire a set of lights, let alone the time to assemble, this set up is cheaper by far. harness length is ample, you get a pair of pigtails with connectors for a pair of lights, the relay, switch, fuse block and fuse, and ring terminals for power all assembled for what a switch and some wire would cost. Made everything quick, cheap, and easy.

Great wiring harness for light installations.
Size: 16AWG Wiring Harness-2 Leads, Size: 16AWG Wiring Harness-2 Leads
This is a great wiring harness for LED lights. These come in one or two leads application. All that means is that they come ready for one or two lights, depending on your installation. The plug in connectors for each light comes with the set so that is a plus. I’ve attached a picture of the plug/connector for the lights so you can take a look at them. Although the relay is an “overkill” for low wattage LEDs, it’s OK to have it just in case you decide to change your lights for larger ones or halogens, in the future. In my case I will be using this harness in my motorcycle. It is very long for my need, which is great for cars, but too long for motorcycles since you have to remember that room/space is scarce in motorcycles. I ended up cutting the wires to my desired length and using heat shrink butt connectors and “glued” heat shrink covers for waterproofing the connection points. All in all these are great quality and I am very happy with them.
