How much can I lower the rear height (with new or compressed springs) before I start affecting the performance of the standard Bilsteins that are fitted?

Nobody can give me an answer and Ive searched everywhere.

Cheers.


MaxSRT,

Anyone that runs the mopar springs will tell you that the drop isn't a big drop. I believe that it is actually less than an inch, but it is very noticeable. Especially in the front. Yes there's a significant gap in the rear with the stock height but with the mopar springs or any springs for that matter it does close the gap a little bit.

As far as just lowering the rear I don't believe that is possible. Reason why is that since the car has "leveling sensors" and if the car isn't "level",codes will be thrown and the adaptive suspension will not work (atleast from what Ive read). I would look at the eibach springs as well. I've seen a few guys with our cars run that setup and if I remember correctly it lowers the car more than what the mopar springs do.

My opinon on the mopar springs is that I ask myself why did I wait so long to install them. The ride is a little stiffer than the stock suspension but still comfortable. When the suspension is activated then all hell breaks loose. Car gets really stiff as expected an the cornering is better as well.


I know its a lot to read but hopefully this helps.

I finally got these done today. The pictures attached are the same day of the install, only hours after the job and alignment was finished. According to the Speedlogix site, where i purchased the springs, the drop is 13mm (about 1/2") back and 20 mm (about .8") in the front. I did not want a significant drop so this worked fine. the installer also noticed the springs will settle a bit more over time. one thing they did note was the camber was hard to adjust once lowered, when doing the alignment. they asked if there was a camber adjustment kit that would supplement this spring set.

ride quality feels to be about the same. i have not had a chance to try on backroads yet. Anyway, this is how it should have came from Chrysler in the first place.

one last note. when i considered doing this last year, the parts were out of stock for quite some time. the dealer i talked to where the car is serviced said this happens sometimes when they switch suppliers. so does anyone know, who is the actual manufacturer of the mopar springs?

Both cars look great guys, but I have a question does any one know what I need to do to drop a 2016 SRT ? that will not affect the use of performance settings.

Regards.....

Hi Yellow Troy,

I was wondering the same, I just took the risk and purchased the Mopar Stage 1 lowering springs (P5155436) I have a 2015 Aus Delivered SRT.

I have had them fitted and they work perfectly. As the other members in this thread have mentioned, its not a huge drop, aboud 20mm in the front and around 15mm in the rear.

I have fitted 22's to my ride also, they sit perfectly.

I hope this helps.

-Michael

Love this but does it help with the “loose” feeling when WOT and does it feel more planted on the highway with cutting down on the feeling of being blown around?
