Alignment and Noise after Installing Coilovers

If the lower camber links are threaded all the way in and still over -2.5 degrees of camber, it simply sounds like the car is sitting way too low. I can't argue about quality considering it's price, but even if the dampers were made of Swiss cheese, the height adjustability and design alone shouldn't warrant alignment problems. If anything i would blame that on the camber arms. Are they longer than factory at the shortest length?

It doesn't really make much sense in either case though. Judging by the decreased caster values you must have even a smidgen of forward rake. Unless the front springs are even lower than the rear.

5 hours for trying to figure what the sound was. I've taken it to everyone I can trust and no one can figure it out. Those coilovers are back in their box now and my car is back to stock suspension. The only bad part is that the front stock suspension doesn't have the brake bracket anymore....so my friend had to ziptie for now. I will likely have to buy new coilovers that are rated comfortable for DD and street driving soon here since I'm not comfortable with just zipties. I know some people do that, but I figure if brake brackets exist....there's probably a good reason why its solid metal haha.

I don't know if it was asked/answered already. But did you get adjustable endlinks for the ASB's?

And what exactly was the sound and feeling you were having? Jittering, popping over bumps, clicks and pops during turns?

I'm not sure you are ever going to find a kit "rated comfortable" for the street. This will purely be determined by the potential spring rating at a suggested height, the lower you plan on having the height, the more convoluted and difficult this is going to be. For potentially "comfortable" ride quality, you'll need about 3-4.5 inches of compression travel from static ride height. This will be a frontal spring rating between 350ib/in and 700ib/in depending on the spring length and ride height. The lower the rating the longer the spring will need to be and higher the ride height. This is just a base. It can become extremely more complex and more expensive from here if you truly want to ride in supreme comfort and lower ride heights.

Your coilover kit can be upgraded to accept these modifications if you don't want to spend another grand. Any either case, new springs is going to cost between 300-800 dollars.

Unless a shock dyno has proven the dampers to be intolerable, they can probably be salvaged. good luck.

I did grab a pair of rear camber arms....from the same place I got the coilers lol.

Yea if I want to drop the ride height, the comfort level will never be the same. But for now, I'm honestly just fine with the stock ride height. I'd want the new coilers just for brake brackets. For whatever reason they had removed them from the front suspension parts during the original install.

Instead of reducing roll with lowered ride height, I'll probably look into a sway bar kit instead. I hear good things about both Hotchki's and White Line.

You can buy new brackets from Nissan.

I'm not talking about the camber arms. I'm talking about the endlink's that attach the sway bar to the control arms. The source of your noise/handling problems could be coming from this. The camber issue is a separate problem.
