Are the front brakes bigger on the sr5/limited 4 runners vs the base model. Reason I ask is because you can only get 15" rims on the base model. I've got some 15" tires I'd like to put on my '97 limited 4runner and since I need tires anyway, buying a cheap set of 15" wheels would be cheaper than a decent set of 16" tires. (i.e. I've got a set of BFG all terrains with 10k miles on them that I wouldn't otherwise have a use for)
