If you mean you need a wider lens for shooting cars, in my opinion, you don't. I used to work for Honda taking pics at their dealership, and I used my 17-55. I have a 10-22mm, but never use it for automotive, just real estate, and landscape. Cars shows are tricky, but I would rather shoot cars at a longer focal point if possible, but i know that's not always possible.
I shoot a Canon as well. 7D mark II, and a few lenses. Most used lenses are Canon 400mm F5.6L, Sigma 150-600 C for wildlife, and Canon 17-55mm f2.8, and the 50mm f1.8 for autos.
I'm picking up my new truck on tuesday, and when i go to belltech's website, they only list the front adjustable struts for rwd which I'm guessing means 2wd? Beautiful truck btw!
