Wavetrac ATB LSD (M66 Gearboxes)Simply put Wavetrac is the only gear diff on the market that does not lose all drive when one axle is unloaded.

Simply put - Wavetrac is the only gear diff on the market that does not lose all drive when one axle is unloaded. Axles become unloaded in aggressive driving, track cornering, extremely slick surfaces, etc. It happens more than most people realise.

We won’t go into torque bias ratios or the concept of how torque biasing diffs work at this point. Let’s get to how the Wavetrac affects performance:

For example, you have a conventional gear diff (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.), you're on a race track for a track day and during cornering your inside wheel bumps over the curbing. This is normal for track driving. The issue is that for the brief moments your inside tire becomes unloaded when bouncing over curbs, your other wheel is not getting drive - is not putting power down. Gear diffs need load on both axles in order to function. The result on a track (or during aggressive driving) is that there are many times when a normal gear diff supplies only intermittent power to the gripping wheel.

Now, same track with Wavetrac: the patented cam device in the Wavetrac prevents loss of drive when that inside wheel is unloaded. The device is able to generate a load inside the diff (to replace the lost load as it happens) that can then be biased to the gripping wheel - in the end making more consistent power delivery through a corner. That makes the car more predictable, and faster overall.

Other benefits:

  • Patented Carbon Fibre Bias Plate for the pinions. All other gear type LSDs run the pinions on the housing, meaning the friction from 0 miles is different to 100 miles, thus effectiveness is reduced over the life of the diff. With the Wavetrac performance is consistent with the Carbon Fibre bias plates!
  • Patented Wave Profile eliminates the effect of a near to and zero load condition drive ability issues found in all other gear type ATB LSDs.
  • ARP Bolts used throughout for superior faster reliability. 
  • 9310 steel gears run in billet or forged steel bodies. 
  • Manufactured & Designed in the USA

WAVETRAC: Smooth is Fast

The beauty of the Wavetrac is that it is ideally suited to high performance road cars that see track use. It is very strong, yet transparent to both driver and traction control electronics during regular driving. On the track or in spirited road use, it provides drive to both wheels without the handling issues that traditional clutch type diffs create (there is no tendency to push/understeer with a Wavetrac). 

The Wavetrac outperforms other gear type differentials because unlike them, it won't lose drive when one axle is unloaded (which happens more often than you'd think).

Lastly, one of the most underrated benefits of the Wavetrac is its smooth delivery of power near the limit. Its patented design makes for a very predictable, smooth addition of power when you need it most - when things are at their limits: on the edge of traction mid-corner and using throttle to keep it there; or coming into a corner a little hot, but quickly back on it to maintain exit speed...

These situations are often subjective to the driver, but the benefit can be felt. The Wavetrac makes you faster because it lets you drive with confidence. Smooth is fast.

Almost Perfect
Color: Graphite, Pattern Name: Mouse
If you are looking for a quiet mouse, this is it. I was skeptical about the "ergonomics" but find that it is much more comfortable for me than the more traditional design for left and right clicking. Simple moving seems fine but its weight is a bit excessive for lifting for repositioning in tight spaces. It is difficult to lift without activating the button on the haptic pad, even set to require firm pressure. A bit more contour on the right would solve this nicely to allow lifting the mouse without repositioning your hand. The forward and back buttons may be a bit awkward for some people. I'm slowly adjusting. Actually, each mouse I've owned needed a bit of getting used to. Side scrolling doesn't always work as it seems it would. Frequently, it scrolls vertically like the "normal" scroll wheel depending on the program. Haptic feedback is not a commonly used feature yet, however, Windows will be slowly adding haptic features to later updates from what I've read. I keep the setting on the lowest haptic feedback level and for what it functions on so far seems natural and not intrusive. There are many adjustments and customizations, too many to go into since I haven't played around with most. So far, even with what may seem like a lot of negative thoughts, I love this mouse. It would be five stars if lifting to repositioning in tight spaces was easier.

As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉

Hey, it works well. Just plug it in and you are ready to go. Only issue, minor, no light or color coding on back to indicate on or off.

Smooth and ergo nice mouse.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
I needed this little thing quickly and got it within 2 hours of ordering. It was only an extra five bucks to get it now. Would have burned more than that in fuel. Works exactly as I would have expected. Perfect.

Simple and efficient
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
This is a dandy little item. Easy to use straight out of the box, No fancy bells and whistles.but why should a mouse try to replicate commands that are on the laptop?
