I have a 2022 Challenger SP WB on order. I wanted to go ahead and get lowering springs to install when it arrives (in production now). Anyone have experience with BMR Lowering springs? Pictures? Thanks.

They sit low as hell.....go with the Eibach Springs!

Thanks for the reply. I was worried they may be really low. Ordering the Eibach.

Get a flat rate spring for the rear

and a adjustable spring perch so you can make it a) even side to side and b) the height you want

Also read up on what happens to the widebodies when you lower them in regards to axle boot damage... and make sure this is something you can live with. It's a very well documented thing around here.

My 2013 challenger that was lowered experienced a leaking boot. At the time I never read any problems with lowering and didn't think much about it. Not really worried about it.

Now, compare the cost of the axle on a Hellcat and the axle on your 2013 . The widebodies have longer halfshafts and lowering puts extra load on them. Thus, their rate of failure is higher when lowered. Hence why I brought it up in the first place.

I'll go on record and say that it isn't if, but when they fail. As, there's lots of folks who got boot failures within 8,000 miles that I've seen on this site alone. I don't know too many people who lowered a widebody and kept it lowered longer than a year. Both people I know personally that did it, both had failed axle boots more than once and both reverted back to stock.

I've never done any work on the rear geometry on a Challenger, but there's a way to lower it and keep everything level. It'll require some fairly serious rear suspension replacements, which would likely cost some serious money. I'm sure there's some folks around here who have done it that can tell you what you need.

Please elaborate. I was considering the eibachs.

And I have a wb.

There's some good info in this thread:

Leaking axle boots if lowering??? Wtf

Ive been reading up and seems a lot of people keep busting axle boots if lowered..... some stock height alao but seems to be more apparant on lowered challengers. Anyone have a fix? I really want to lower my care more but just dont want to deal with the hassle

Hmm not a lot of info there. I’ll keep my search going. Just seems like it may or may not split no matter the height.

Stock the angle is steep

11+ °

Frame it tub it

Lowering increases the working angles of the CV joints which in-turn causes the bellows on the boots to rub against themselves due to misalignment.

I can go to the garage and grab a half shaft to demonstrate this if it is beyond anyone's grasp.

A lowered car, under compression, has serious camber gains which further exacerbates the issue.

So either you realign it with custom arms, or change the layout/construction of the half shafts to something without a cheap boot.

The above is a general comment on what the rear does at lowering. With a widebody car, the angles are the same, but the length of the halfshaft puts compounded stress on the boots, which accelerates failure.This is why you see a lot of air ride systems fail as well. With air ride, the lines can get pinched or cut if they're not routed well away from obstructions, but due to how low they bring the car and increase the negative camber, it greatly wears on the axle boots. Eventually causing a failure. So long as the car isn't driven when lowered near the max of its depression, it's not too bad. But there are people who like to drive it slammed... and those people might get weeks or months out of their axle boots on a widebody.

I have used Mopar stage 1 springs which I liked the stiffness on. The eibach prolines I have now seem a bit soft but look nice, front sags after a year though. Image is with eibach prolines on 20x1.5 with 305s, I get no rubbing.
