You should have the helper spring on the bottom... not the top.
Because?

And that's with the helper Springs correct? I would be happy with 26". Tonight I'm going to try and preload the spring enough to drive it while I wait on the helpersAlright, I took some pics and measured my current ride height.
I'm sitting at 27" right now, measured from the floor to the top of the front fender:
(I will drop it down to about 26.5" to 26" after I install my bumpsteer kit.)
I also snapped a pic of the front struts and where the collar is at:
As you can see, I have pretty much the entire sleeve-worth of adjustment. It's currently at the top of the sleeve. I suspect I can easily get the car down an inch.

less chance of the coupler between the two to shift when its down around the strut. More of a "just incase" kind of thing.
Talked to Strange about it and they said 10" 350lbs was too much unless I have a big block (has he seen the size of a mod motor?) , and that he recommended a 12 or 14 at 175lbs. That sounds waaaay too soft for me. This isn't a drag car...
I'll try to loosen everything back up and retighten it tonight. I still have stock A arms and didn't loosen them up, but maybe something in the CC plate is binding?
Why is a 350 way too much? What are the disadvantages other than a rough ride? Are you saying that could be part of my issue?
They're H&R supersports in the back, but they're getting replaced with coilovers when I find a kit I'm happy with. I've been looking at around the 425-475 lb range. I said in another thread, this coilover stuff is confusing just based on the number of different accounts. Even different manufacturers and tuners will say conflicting things. Strange says they're too stiff and MM said they shouldn't be an issue. I have no problem taking these back apart and throwing regular Springs back on it if I have to order the right spring rate and length.I'm not about to read the whole thread... ADD is way too bad tonight. What spring rate are you running in the rear? If you've got stock location springs back there, they better be damn near 500lb/in.

What is it exactly that you are going for? The rates you have are up near racecar levels. I run 175 front and rear, and when I tell you it's far from soft... I mean it.
Right off the MM website, they give approximate conversions for spring rates based on location, to wheel rates.
When you make the conversions and look at the factory 96-98 Cobra WHEEL RATES, you see that the front is about 100-126lb/in, and the rear is 82.5-132.5lb/in (progressive springs). When you compare these to the 94-95 Cobra (mine) the rates are similar, but linear, with a 100lb/in front wheel rate and 82lb/in rear wheel rate.
You state that you have H&R SS springs, which have a spring rate of 275-300. This ends up being a wheel rate of 137.5-150 lb/in, which is obviously slightly stiffer than stock.
HOWEVER, and this is where the craziness starts...
Your 350 lb/in coilovers springs have a wheel rate of 315 lb/in. This means that you have more than twice as much spring in the front, than you have in the rear. This is going to create a handling problem. Your car is going to have an overwhelming desire to understeer, which defeats the purpose of your suspension work. If you were to keep the H&R springs in the rear, my recommendation would be to run a 175 lb/in spring. This will bring the car back into better balance, while also giving a nice ride and a moderate improvement in handling. I personally run 14" 175lb springs.
Damn the information in this thread should be a sticky...
I called Strange again to find out what their struts are rated for. This guy I talked to said 150-275 so for a car that is Street driven with a little track use, he would recommend a 200-250. Summit also said I can send the 350s back and exchange them so when I get back in town the regular springs are going back on and I'm shipping the hypercoils back. That gives me some time to decide. Admittedly I rushed into this without doing enough research. Now I know where to start off. Thank you guys for helping me with my screw up.
Edit: Also, based on what Strange said, you could also run the 175's if you wanted to. It's in the range of the strut.
I recommended the 175's because they would be a good match for the springs he's got in the rear. If a stiffer rear spring would be installed, then the 225-250 in front would be a good choice.
