FITS: Mk1, Mk2, Mk3 8v with 4 or 5-speed 020 trans

The Wavetrac differential uses a patent pending design to improve grip in low traction conditions. Precisely engineered, converging / diverging wave profiles are placed on one side gear and its mating preload hub. As the two side gears rotate relative to each other, each wave surface climbs the other, causing them to move apart. This imparts an increased normal force through the side gears, increasing the bias ratio as a function of load. This increase occurs automatically only when conditions find it necessary, and it 'reverts' back to its nominal bias ratio quickly and seamlessly, maintaining optimal drivability and performance at all times. It's like having two differentials in one: you get the benefit of a higher bias ratio when needed without detriment to the car's handling.

Interchangeable Friction Plates Provide Controlled Bias

Here's somethonaling else you won't find in any other design:

The Wavetrac diff's behavior can be altered in the field to suit your needs. It comes standard with carbon-fiber bias plates for the best all around performance. Interchangeable plates using materials with different friction coefficients to fine-tune the bias ratio are sold separately.

These friction plates provide a mechanism to tune the response of the differential as a function of applied torque load. The applied torque load manifests itself as an axial load from the differential pinions into the housing. This axial force is then considered a normal force into the friction plate, and as a function of the effective coefficient of friction, will provide a resistive torque to the rotational motion of the differential pinions. The resistive torque will add to the resistance of relative rotation of all components within the differential. The resistive force, however, is non-uniform since it is a function of the axial load from the differential pinions. The unbalance of the resistive torque will manifest as non-uniform energy absorption within the differential causing a bias ratio.

Superior Design, Materials, and Construction

Designed from a clean sheet, the new Wavetrac Differential brings current gear technology to the market. Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high.

Each Wavetrac Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac differential is built exclusively using high quality, high strength fasteners from ARP, the world leader in fastener technology.

Not quite premium, but a very nice Bible
Format: Leather Bound, Format: Leather Bound
I’m a Bible snob and I have a few issues with this Bible, but it’s currently listed at around $77 on sale and many of my Bibles are $150+ so I’ve still given it 5 stars as it is a nice Bible and very reasonable quality for the price. If it’s what you are looking for, I would not hesitate to recommend it. My issues: Page thickness and opacity. The pages (especially for a journaling Bible) could be a tad thicker and more opaque. That being said, certainly not the worst I’ve seen and they are passable. The paper does have a really nice softness, that’s almost cotton feeling (and less tissue paper feeling) - which I do like. No line matching. Many premium quality Bibles will line match the text on the front and back of the page to limit the distraction of text that shows through the pages. This Bible is definitely not line matched. The cover design is not overly practical for travel. The leather strap is meant to be tied in a knot. There is also a bump on the back where the pen holding elastic is installed inside the cover. Both of these feel like they will easily catch and cause uneven wear if you plan to carry it in a book bag with other flat things. Things I like: The pages feel nice. Having a real leather cover does feel nicer than a flimsy cover It lays really nice. The text is small but the layout is compact and clean looking. The limited footnotes are a mix of translation notes, contextual notes (like measurement conversions), and references. They are very brief and limited notes, but I like the hybrid of information. The ESV translation, while not my favorite as it tends to be a little more evangelical, is a very solid translation and used by many churches. Overall it’s a nice Bible and I could easily see it being a companion in someone’s faith journey for many years to come with a leather cover that will age beautifully and space to keep notes and thoughts along the way.

Useful Bible for Taking Notes or Writing Out Prayers in Response All in an Attractive Format
Format: Leather Bound
First off, I won’t be reviewing and evaluating “the Bible”, because the Bible is supposed to evaluate you, confront you, call you, and claim you for God. So, whether you read this edition or another, let God’s Word teach, woo, and draw you to Him! As for this edition of the ESV, as some have noted, the font is on the smaller size, but still readable for most (your results may vary!). As it is a journaling Bible, on each page is a wide lined section for you to take study notes or sermon notes, make comments, write out prayers in response or whatever use you want to make of it. If you are new to God’s Word, the publishers have included some helps in the introductory matter, including a page on ‘Why Read the Bible?’ and several pages on ‘What the Bible says about...’, covering various topics and where to find them in Scripture. There are introductions for both the Old Testament and the New Testament. And after the end of the Scripture texts (Revelation), the publishers have also included some helpful resources like, ‘God’s Plan to Save You’, ‘Introductions to each book of the Bible’ and a plan to read through the Bible in a year. The leather has a very nice feel to it and (I hope) will wear and age well. The strap is new for me, but it was pretty easy to use to keep the Bible closed. (Maybe it’s just me, but it’s a little odd having such a long strap hang while I’m reading it!). There is also a leather loop inside to keep a pen handy for your note taking and journaling. By the way, the size is a little unique, as it is almost square, so it might be an awkward carry, and I would guess for women that it might only fit in a really large purse. Overall, if you want a Bible to use for more in-depth study and to take notes on what you find, this might be a good choice for you.

Nice quality ESV 2 column Bible
Format: Leather Bound
Nice soft cover. It is smaller than the hardcover ESV journaling bible I have, which isn't necessarily a problem. This is also a two column bible. The font is 7pt, so it is fairly small. It's also fairly squarish at about 6.5x7.5inches. The strap comes separate, which is nice because if you don't want to have to tie and untie your Bible every time you want to open it, you can just leave it off. There is only one ribbon, but I honestly tend to use bookmarks more than ribbons anyway. There is also a pen loop inside to hold a normal-sized pen (probably won't fit a large one) Content - Ownership page - not dedication, just this Bible belongs to - An invitation to the journaling Bible - Copyright page - printed in China, 2001 version - Contents - Why Read the Bible - 1 page - What the Bible Says About - 5.5 pages giving scripture references for various topics - Preface - Standard ESV Preface - Explanation of Features - short 1-page note about things like textual footnotes and cross-reference footnotes - The Old Testament - 2 page introduction followed by the text - The New Testament - 2 page introduction followed by the text - Plan of Salvation - just over 3 pages - Introductions to the Books of the Old Testament - It seems weird that they are at the end and not with the actual books. There are about 5 introductions per page, so they are really short - Introductions to the Books of the New Testament - Same note as above. Is it really an introduction if it is at the end? - Through the Bible in a Year Reading Plan - Daily dated reading plan that includes OT, Psalms, and NT each day. It will have you read through the OT once, Psalms twice, and NT twice

Works great, easy to assemble.
Size: 2 Tier-9.5''Wx10.5''Dx9.5''H
I bought this to try and contain our cabinet clutter. It works really well. Was easy to assemble. I use it on the countertop instead of inside of the cabinets. Looks nice enough to sit out. Will buy 1 more in the coming days. The storage areas pull out, makes for easy access.
