I finally got around to halfway installing my SRT-6 Springs on my Limited this weekend.
Got the rears done first since they were the easiest.

Upon removal of the stock springs I found out that the SRT-6 springs are an inch shorter than the stock limited springs. So I managed to lower the car as well as stiffen it up.

The car hasn't really had time to settle because I keep putting it on the lift, but from what I can tell it around a 1.5" drop in the rear. I already had the thinnest spring pad on the car as well.

As far as handling goes, at your typical surface street speeds its not noticable unless you get into big bumps, potholes ,etc. It's very noticable at highway/high speeds. Car feels more planted, more precise.

UPDATE 11/21

Put the fronts on tonight at the shop. All I have to say is without a lift and a transmission jack this would have been totally impossible. Took 4 hours to do the fronts, if you include the beer run and exclude the stop at steak and shake (where my iPhone was stolen :/)

I also trimmed 1 coil off of the fronts since theres no way in hell I'm going to pull the front end back apart until I get my 1 dot spring pads (my stock fronts are 3 dot atm)

Overall, its like night and day. Car is much more stable and smooth. Rides like it should have to begin with. You can now feel every expansion joint, ripple, etc. Car doesnt wallow or wander.

Examples:

Highway interchange, broad downhill right hand sweeper. Normally at 65 the car would just feel unstable and wobbly. Tonight I took the same interchange at 95 without a single issue.

Exit ramp to get to my house. Uphill decreasing radius right hander. Normally at 55-60 the car would push and get loose, now I can take it at 70 and thats pretty much it due to tire limits.

I offically love this car again. Body roll is gone, and a 2nd gear clutch kick no longer results in the car flopping around, but immediate loss of rear wheel traction

also alot more stable from dig launches, before it would wallow, now it just spins the rears and takes off like a rocket.

Will have photos tomorrow. I hope

 

what about the front? did you do them yet? let me know,,

 

Not yet. I did the rears at home. I need to go down to the shop and put the car on a lift to do the fronts

 

I put limited on the front of my srt and it lowered it about 3/4" when i did the rear, the rear end of the car was 4" higher,,
so i am thinking the front limited springs are longer than the srt,, here is what i have
my srt rears are still in the car.
The front i have a set of limited that lowered my car 3/4". don't know length
I have 8 ea springs as spares
out of the car measuring from coil tip to coil tip
4 ea 14" tall dia. .555
2 ea 13" tall dia. .610 these are front srt
2 ea 12 3/4 tall dia. .530
it seems all crossfire springs are 4" circle
I really am confused now ,, what are the length and dia of your rear springs.

The limited springs should be longer since they have smaller coils (lower spring rate) and they still have to support the weight of the car. So with a longer spring, the static sag due to the weight of the car will balance out the difference in length vs. spring rate.

also, the SRT-6 does weigh slightly more, due to added engine components, as well as the added weight from brakes, suspension components, etc. and the automatic transmission is a pig.

my stock limited rears measure .530 and roughly 13" tall
the srt-6 fronts i have measure between .610 and .586 (exact)
and are roughly 14" tall

 

Infinite, please keep us posted on this. At the Dragon, all I could think of every time I rubbed was that a stiffer spring would be great and I sure I can get a set off someone who has upgraded for pretty cheap. Thanks.

 

sorry for the lack of updates.
full time college + 2 jobs = hell.

Ive been driving the car alot and it feels alot more solid now that the springs have had time to settle. Still needs to go lower in the rear.
Im hoping to have the fronts on some time this week provided I have some free time.

 

updated first post

 

When i did mine i thought the front was easier than the rear... did mine on the ground in about 3 hours i had the miller special tools spring compressors tho...

 

the rears took me like half an hour, way easier than the fronts.
if i had the miller compressor it would have been easy. but i didnt, so i took the long way, lol.

 

Thanks for the info infinite, I think I am going to make this the winter project. I am planning on buying several different sized (dot) shims so I can more tightly adjust where it sits, can you point me towards a good place to pick some up? Thanks.

your best bet is the dealer.
I need to get one dots for the front, but the dealer near me, the parts guy is a moron (no lie)

still need to take a coil off the rear.
