you don't have to worry with binding the uppers unless your taking some serious g's and your car to its cornering limits, yes uppers help keep you launching straight - but really unless your pulling a wheel its not really necessary - but its good peace of mind. How many of you get sidewayz when you try to do a standing burnout? Mmmmmm... not me
They are worth the money. Much better for handling for launching at the dragstrip. Also work well in cornering as well.
I have Maximum Motorsports and I love em.
