Whether used on the Street, Strip or Track, all MFactory Helical LSD's come with a Lifetime, No-Hassle, Globally Transferable Warranty

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

Nice Suit
Color: Deep Grey, Size: XX-Large, Color: Deep Grey, Size: XX-Large
Great quality for the price. Purchased during a flash sale. Comes with a bowtie and crown pin. My husband is 6'3 and 215lbs. This is a slim fit and the pants fit well without a belt. He normally wears a 36×34 and this suit was an XXL. He has big biceps and the jacket fits well in a relaxed state, but it's a bit tight when he lifted his arms or flexed.

Love this tuxedo! I purchased this tuxedo in a size Small for my son to wear to a wedding. He is 5”10 and weighs 180 lbs. Everything fit well except the pants needed to be hemmed a bit. My son looked very handsome in this tux and received several compliments. Great buy!
