Adding a couple of things to my list.
1. Better contrast ratio between the LCD digits and background.
2. Easier to clean forged wheels. Specifically, use a ball-end mill bit instead of a square-end bit for the machining, and simplify the design. Also, my wheels have a very porous, rough silver paint which makes it almost impossible to get brake dust off. Had I known how bad these wheels are to clean I would have skipped the LSS option and bought a set of forged Volks.
P.S. I suppose another option would be to offer "brake dust gray" powdercoating.
