...but the ratio is closer to 3:1, I runn 700lb front springs, and people who know more about suspension tuning than me influenced my suspension, and it works. It uses the bump-stops a lot, and the tire rubs in the fender...but it works.

You're right, I neglected to consider that. But I've read a few times the wheel motion ratio is more like 1.6:1. I doubt it is 3:1 unless you are running a super low offset. The wheel motion ratio on my other car is around 2:1 in the rear, which explains why I can use a 16kg/mm spring rate on the rear of a FWD car.

Only reason I mentioned your setup along w/ fooger's is that your setups are superior due to having more travel than chricto's and my setup w/ dual adjustable shocks. I am not sure why he took it the way he did, I just did not think longer bumpstops would do anything to solve his case. I'd rather trim the bumpstop (after checking how much travel is available) than putting in longer bumpstops for the shock to contact against.

So, what a minute. What you are saying is that bump stops won't help me, in your opinion?

Look dude, I know you are just trying to help, but you are annoying the **** out of me. Maybe I wasn't clear enough with my intentions, or maybe you aren't reading all of the posts in this thread. Either way, here is some paraphrasing that will hopefully clear things up...

My rear suspension ride quality is harsh. Spring length and coil bind have been ruled out as potential problems.

I initially was just going to get stiffer springs all around. Then other people started recommending better bump stops as a partial solution...

I'm as low as you are, I'm on 200/300 springs with Illumina shocks, and most of my ride harshness is actually from having 949 end links that wear out every 6 weeks or so.
So I said...

I still want to get some better springs in the rear, too, but I've got more important things to spend money on right now.

Ride quality has always been the issue. This car sees 30-60 miles daily and I need a little better of a ride until I can get a second car. After Brain suggested some $5.00 bumpstops, I decided I'd try them out. I still intend on getting new springs, but as I stated before, it's not in the budget right now. I'd rather spend $10-$15 first than spend $150-$300 on new springs.

chricto, I know you've been annoyed by me, but I've done some work on mine recently with success as far as ride height. As much as you want to deny my advice, I strongly believe this will solve your issues so I am posting regardless you want my help or not LOL. As I mentioned, my zipties pushed up the bumpstops all the way up which makes me think they are bottoming (again it doesn't feel like it's bottoming, so maybe the poly stops my coilovers come with are soft and progressive). The ziptie in the rear shocks were even worse and chewed away some of the bumpstop material and it was pressed into the bumpstop.

This is my front, with 3" of bump travel, my tire bottoms the fender as the the shock uses up the 3" of travel. The included bumpstops were the perfect length up front but the same 35mm bumpstop in the rear bottoms out the shock prior to the tire.



Again, that is the front. Testing the shock without spring, jacking up F-LCA to the point where the tire bottoms out, is where the black 15mm bumpstop ends up. I replaced my 35mm bumpstops all around with shorter ones (as well as raised the height a little as I had spring sag to reach my old 4.125"F 4.375" pinch weld heights). I used 20mm front stops and 15mm rear stops. After the new bumpstops, ride quality is improved. It probably still hits the bumpstops on really bad potholes and what not, I won't know for sure til I check where the zipties end up.

Those longer bumpstops will just make it worse in my opinion if you are hitting them all the time.

Sorry for the late response, errbody. Sorry for the minor freak out, too, Green. I know you are just trying to help. I'm not hitting the bump stops all the time; just over large bumps. There is a **** ton of road construction going on in my area, and it's like I'm literally taking a rally stage to work every morning. My suspension problems are only so prevalent right now because of all of the shitty roads in my area. The bump stops have helped so far, but better, slightly stiffer springs are still in my future plans. I've got a long line of maintenance issues to take care of before I even think about getting new springs, though. Thanks for the help folks.
