Well, I used to have Intrax, but now have Ground Controls. Two reasons why I switched
1. Since the front stock springs are so big in diameter, they sometimes "shift" a little, back and forth. Nothing major, just annoying. The Ground Controls come with smaller Eibach springs, thus eliminating the annoying shifting noise.
2. Adjustability. GAWD, I can't even imagine a tow truck trying to hook my car up with my body kit...NOOOOOOOO!!
There are a lot of shops out there that would think that since you lowered your car, they think something like, "you should have thought about aligning your car before and after you lowered it." I got that look a couple times trying to align it after being lowered. One shop was like, "Is it lowered? Nope, can't do it." What a bunch of assholes, NAH MEAN??
After my springs were installed, and before my alignment, the inside of my tires were severely wearing. It took me a while to find a place that was willing to do it. SEARS. All I said was, "Naw man, I didn't lower it." Two years later, which is now, there is no uneven tire wear. All it was, was the front wheels were toeing out. Toe in/out is adjustable on our cars. My car slightly cambers, but not enough for uneven tire wear. We don't have upper a-arms like hondas, which makes it look like their tires are at a 45 degree angle when slammed.
The bottom line is, I've got GC's on the lowest setting, no camber plates, with no uneven tire wear. Just get a proffesional 4-wheel alignment. Electronicly.
Sorry so long...
