Ok, Im having trouble finding a straight answer. I am looking to buy H&R lowering springs, I need to know if I NEED to buy the camber arms because this drop is "significant" apparently and causes the tow of the tire to be all off and yadadada. Also I plan on running these springs on my current set up which is the msp racingharts on 225/50/17 tires. I want to go back to the stock 18s but run 225/40/18. Would I rub on any of these combos. I would like to run a thicker sidewall in the future like a 45series with 17x8+45 rim would there be any issues there?. If anyone has advice on this please let me know. I found answers but the threads are kinda outdated just want current info thanks.
