No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

Beyond beautiful!
Color: A-White, Color: A-White
This arrived in a beautiful bronze box protected by a cellophane sheath. Inside, the watch is amply padded with black foam; there are ample instructions and a tool to remove links. The rose-gold watch measures 9 inches long with all of its links attached and is protected by cellophane and a removable film. The watch face is a very light silver with clear rhinestones as most of the numbers, has rose-gold hands with white centers, and is covered by a watch glass with faceted edges. The rose gold band has six charms- three on each side, framing the watch face. Four are clovers with stippled edges and a faceted clear rhinestone center. Two are a cluster of four hearts- 2 solid hearts and 2 hearts with three clear rhinestones in the center. All of its edges are rounded for comfort for all-day wear. It's also water resistant for hand-washing. The face measures 3cm by 2cm which is the perfect size. I'm a dress size 4, 122 lbs and I removed 2 links, so plenty of room for all sized women. I cannot say enough about the quality and beauty of this watch. The pictures don't do it justice. Just gorgeous! Amazing value.
