if you really think you want TJ springs in front....
go get one and really look at it next to the kia
it just doesnt work....I thought long and hard about that too only because they came with the set of rear springs I got they are completely different. A set of spacers in the front from Dennis is what I'm going to do for my front(soon as I can spend more play money

the spacers are a better option because when you lift the front that much you need longer struts and there arent any for the sportage the spacers lower the struts and give the extra lift you need solving the longer strut problem.
