Do the rear springs sit right? Or will they sit flat after car is back on the ground. My rear springs look luke theyre on an angle and not flush.

If you were to swap out the rear springs on the Raceland/Rokkor coilovers with stock ZHP springs, would you lose the ride height adjustability of the rear?

Also, Im sitting on stock ZHP wheels. Am I going to need spacers to go with this setup? Im not looking to slam the car, but lower it moderately to eliminate the wheel gap. Im looking to go with the Rokkor kit.

yes you will lose the height adjustability feature if you swap the springs. And whats the offset on the zhp wheels?

Have the rear shocks on the Rokkor kit been known to firm up as they break in? Im on a stock ZHP suspension with 63k on it and it may or may not be blown (I have nothing to compare it to). I definetly do not want to lose performance but I also want to go low for cheap, and retain the performance of a stock ZHP.

So far, the Rokkor kit is looking like the right kit for me. Is there any word of how many miles some people are getting out of these kits? Im looking too get like 30k+ but im thinking that may be too hopeful!

The offsets are: 18x8 et47 front, and 18x8.5 et50 rear. Fronts have 225s and the rears have 255s.

Keep in mind rokkor and raceland are made by the same company. So they're ideally the same kit just different name and color. The rokkor's are said to have stiffer spring rates but thats something that you probably won't notice if you drove two cars with raceland on one car and rokkor on the other. They'd feel very identical. Having said that, you will most likely need spacers in the front. Since your gonna need to space the front out, you might as well buy spacers for the rear so it matches and doesn't look unproportional. You also don't need to swap shocks out of the rears on these kits, its just mostly personal preference for people. I drove a good 4-5 months with them before swapping them out. The only reason I swapped them out is because I needed a stiffer set of shocks because I rubbed like crazy with each bump, hump, or drop on the road or highway because Im running an aggressive offset, something you won't have to worry about. I suggest your entire set of rims out to your personal preference, i'd say 10mm in the front, maybe 15 in the rear. Try it out, see how it is, and go on from there.

Also, if you'd like to check if your zhp suspension is blow (which it probably isn't) go outside, to the rear of the car, push down on the trunk. If the car is easily able to be compressed down and bounces a lot, then it's most likely blow. Do the same thing for the front. If you can easily push down on it, and its bouncy then it's blown. You can also use this test on another car, a car you know for a fact that does not have a blown suspension (a brand new car that you know somebody owns) and compare the two.

Thanks for the info! I just checked to see if my shocks were blown and this is what i found:

The rear is very firm and difficult to push down, but makes a squeaky noise when you push down.

The front, on the other hand, is significantly easier to push down on and a lot more spring. It took very little weight to push the fronts down on both corners. Does this mean that the front shocks are possibly blown?

Oh. I think most susp goes out around 75k. Its possible yours are still ok but should be changed out soon. I also know most rears go out first. Most. Only way youre gnna know for sure is taking it out and inspecting it. Since youre thinking going rls, jusr get em. Just dnt buy the endlinks the suggest and go with the autozone ones instead

my suspension was good at 90k. i still swapped it out. you could possibly have a blown front, you can take it to a mechanic just so he can take a look see. He can do more than me in terms of telling you if you have a blown suspension or not, theres only so much i can do, you know? The sqeaky noise is normal as well.

And if you do go with this suspension, buy ss impala endlinks. theres a part number somewhere in this thread. you need it for the installation.
