Best suggestion I can make is if you are just getting the car, start with hexs now. If you have a ton of tires, buy all the stuff to convert to hexs and keep it in your box so you can run both. All your new rims you buy, get in hex form. That's what I did until I had gotten to a point where I only had a few sets of tires left on std. I gave em to a buddy and moved on. I still keep the setup in my box just in case.
