This hasn't come up at all. The only discussion we've seen are from those looking for aftermarket running boards. We haven't seen any postings yet for this product. Several members have commented that they wish the car had a higher road clearance.
suspension mods don't void the warranty on any other part of the car normally. I'd love to lower the car a bit, but would it look weird? maybe just go w/ bigger rims and tires. Then a big brake kit. hehe.
