Looks easy compared to doing that job on the front of my Crown Vic
"Some my think it's getto" 😖what exactly do you mean by that?
Did you have to do a wheel alignment?
Thanks for the post.

Welcome aboard Coop6 and here is a useful diagram on the rear springs.  Z    https://drive.google.com/file/d/1u3aNz_Uo3BWKp8gsZYLJKRUkD9Ziw_xwShgX85Jp9OziPRIN81ckWFVgikaBlwYvspZB-TccNmGMMd5L/view?usp=sharing

Thanks for that info! If I'd like the rear almost level, maybe 1/4" higher, how much coil should be cut?

Has anyone cut a little of the front coil with success? I just don't want to ruin the ride quality. I just don't want to go as low as the hr springs.

The only way to get an accurate amount to cut is to follow the instructions on the website linked in the first post and measure your spring.
You cannot cut the front Springs, they are squared on both ends

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Did this yesterday. Was easy. Needs camber adjustment bolts. There is a little spring droop which means that at full extension, the spring is a bit loose compared to stock.

Man, that looks so much better. I hate that the wifes car looks like it's rolling around in heat all the time with its butt up in the air.

Does anyone know if H&R springs are a smidge loose in the seat? Wondering about safety when jumping rail road tracks lol.

You cut off a little more than I did.  Do you have a the PP with stiffer springs?  You should be able to get it aligned just fine.

The rear H&R spring out of the car are not much if any shorter than the stock spring. When installing mine I put them side by side and was surprised how close the height was. Visually just sitting on the garage floor you couldn't tell the difference in height.

I'm guessing H&R uses a lower first rate in their progressive winding, so it sags further under load, but still provides a little preload when the suspension is fully extended.

V347, how much did you cut off the springs?
