Dimensions After Drop ?
I just installed a set of H&R Sport springs 2 days ago, and measured before and after. I measured the height from the concrete floor to the fender lip, directly in the center of the wheel. This is what I came out with...
Fronts Pre-Drop - 26 7/8" Rears Pre-Drop - 26 11/16" Fronts Post Drop - 26" Rears Post Drop - 26" (Driver's) & 25 7/8" (Passenger's) Front Drop Total = 7/8" Rear Drop Total = 11/16" & 13/16" This comes out to nearly the same drop in the front, as in the rear. Is this the same with everyone else? I was actually hoping for less of a drop in the rear, and a little more of a drop in the front! My 305-30-19's do rub the fender every once and awhile. Especially when I had 3 1/2 people (7 month old) in the car tonight. I had to drive very carefully, with the EDC set to Sport. If I keep having a problem, I will either have to throw the stock springs back in, or change tires. In Nitto Invos, I can go to a 315-25-19, and that will give me about 1/2" more clearance, and give me a wider tire. I would win both ways. This would mean that I would have to buy new tires though, and I don't really want to do that, as I just bought these. Let me know what measurements you guys may have come up with when lowering. Don't forget to tell which suspension you are running. -Andy

I'll have to measure and I'll let you know. You do realize that the suspension will settle some right? Just drive it a little to get the suspension to load and unload. Then align the car. Whenever I get the measurements, I'll post them on here.

Thanks! The suspension has settled quite a bit from where it originally sat right after installation. I don't think it will settle much more. Your measurments are greatly appreciated. I am sure they will differ from mine, unless you have the same size wheels and tires, so please also list your wheels and tires.
Mine - 275/30/19's & 305/30/19's -Andy
