My honest opinion here is to forget about the budget boost system altogether. I installed one of those when I first got my Jeep thinking that it would make it look better because I too was not big on offroading at the time. It was one of the biggest wastes of money to date. All you are doing is mashing your springs by putting in some rubber spacers to make the Jeep look taller. Because of the big wheel wells, everyone can see that block in there and it looks weak. I suggest saving your money and putting it toward a complete suspension lift. Because you don't do much offroading, don't spend $1500 on a lift kit. You can get a Rough Country 4" suspension lift system for under $500 and this will give you everything that you are looking for. Not only will it allow you to run bigger tires, but it will give you the performance increase that you wanted. Deep snow will no longer be a problem and you will be able to skip that buyers remorse that occurs after installing a budget boost. When a lifted Jeep pulls up beside you, you may experience some jealousy and anger at not spending the extra money. Just some advice from someone who has been there before.
