No doubt that by Toyota offering those springs as an option it adds confidence, that's huge actually. I guess you're right if you only drop it 1.5 inches it shouldn't affect it much compared to something way more drastic. Let us know how it rides and if it sits too low if you load it up with people, stuff in trunk....
I drive people around all the time although they're not heavy or anything
Those parts that came with your sprints in unboxing video in plastic bag, were those bushings? Also, can you provide the spring part number, where you purchased from and price...Really appreciate it. Man, I've always debated whether to drop my cars in the past but never had the balls to do it. I've done pretty much everything else but never suspension. Finally my last car was a 2000 4runner Limited which I drove from new to about 2 years ago. Loved the car but with new baby, I needed something newer with airbags everywhere if you know what I mean. Thanks again!
