You can tell immediately I tested it out because I was skeptical about it. There is an on-ramp which I usually have to take at around 40 mph with wheel screech after the bar it was at 60 with wheel screech. In sharp turns it is where the bar really demonstrates it usefulness. Completely worth the buy.
Becareful with those underglow lights, I had them on my Supercharged Toyota Solara and one winter later..... 3 outta the 4 bulbs cracked. Wasnt even the snow that caused it to break, cause it hardly snowed that year. It was just the cold that did it. They were a complete waste of money. Never again.
