Well some people experience some camber at 1.25". I know someone with a Celica that has the TRD
lowering springs, which is 1.25" and says she has some camber problems. But if you say you never had a problem, I believe ya, maybe some just don't have an issue.
And no, I wouldn't be satisfied with a 1.5" just because I wanna lower my car to the point where I'm not driving, I'm grinding, haha! Just personal opinions, it's up to you want you really want. Plus, if you don't like the drop after it's been settled, I'm sure you can sell it without losing too much money anyways if you want to chande it up. Up to you man, hope you make the right choice for you!
