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

Great fabric & plaids! Quality construction.
Fit Type: Slim Fit, Color: Light Blue/White, Plaid, Size: X-Small, Fit Type: Slim Fit, Color: Light Blue/White, Plaid, Size: X-Small
"Light Blue White Medium Plaid" has an overall pale aqua coloring, well represented by the product photos. it's even prettier in person, with a pale purple/pink stripe and other subtle touches. 5 STARS FOR: - Fabulous 100% Cotton fabric gets better with every wash. - Thin (but sturdy) fabric, comfortable working outside in hot, humid SW Florida. - OFFERING XS SLIM-FIT: Finding this XS in a slim fit Men's shirt was a game changer for me, a slim 5'7" woman with long arms, broad shoulders and slim hips. The AE Women's version of this shirt is boxy with laughably short sleeves, and is not offered in slim fit! - Quality construction throughout. Good attention to detail, eg, matching patterns at the pocket and front placket. - FABULOUS PLAIDS, many are unique and subtly complex. - ATTRACTIVE COLOR OPTIONS, lots of different Blues. I've also enjoyed the paler (some might consider more feminine) colors like lavender, pink and pale aqua. - UNBEATABLE PRICING, ESP ON SALE. At full price, these would be a good purchase. I put my favorites into the shopping cart, and wait to be notified of sale prices. I've purchased five shirts for under $10 each, by watching for sales. PAID: $7.67 on 1/24/2026 for XS in "Light Blue White Medium Plaid".

Comfortable and well made.
A well-made, cotton shirt, suitable for casual wear. I like to wear this in the summer untucked with the sleeves rolled up over a colored t-shirt. I found the tail of the shirt to be a bit too long to wear untucked without looking odd, so I had it shortened; now it fits perfectly. It is made of cotton, so an iron is mandatory if you don’t want to look like you slept in it, and it will get some wrinkles as the day progresses, but that’s cotton’s nature. I liked it so much I purchased a second one.

Nice shirt, runs a tad small.
Fit Type: Slim Fit, Color: Light Blue/Indigo, Plaid, Size: X-Large
I guess that slim-fit is not for my hubby and this is a little too fitted across his pooch belly. But he loved the blue color plaid. Fits well elsewhere. If you're not a flat-stomach, dont bother with slim-fit I guess.
