I was looking in Summit's new catalog that just arrived and was looking at their wheels. I'm interested in buying some wheels for my Z. I really like the look of the Weld Draglites for the front and rear. I don't want skinnies on the front, but it said that these wheels are made for drag use only. Why can't you drive these on the street? Not tough enough? If that's true or a safety issue, what wheels could I buy that are street legal? Do they have a set that looks like these Weld Draglites that are perhaps made by someone else?
