Shock absorbers Bilstein or OLD MAN EMU

H&R sport springs 40mm, Bilstein B8s.

Yes it really is cheap but I really recommend slurging for the Bilstein oe replacement shocks.

I’ve been happy with the 6112/5160 bilstein combo. I just did it it at about the same mileage 245k. Rides smooth and absorbs bumps pretty well.

My factory shocks were all totally blown and I did replace those with Bilstein 5100. You lose the electronically adjustable shock valving by not replacing with factory but...meh.

I actually did Bilstein 5100 all the way around with .85” lift in front (to “level” out the rake) but kept my rear airbags and did a slight adjustment to the rear ride height sensors for the level. Mine rides great and I like that I still have the self leveling rear.

Koni makes excellent shocks. Bilstein is number one and has been in my 70 years on this planet. There’s just no substitute for a Bilstein.

They are a little stiffer than stock. I’ve had Bilsteins on a 4th Gen Camaro, an 2002 Grand Prix, and a 2007 GMC Envoy. They were stiffer and improved handling on all the vehicles they were put on. You won’t be disappointed with the 5100 if you are looking more a little more performance than stock.

I ran Bilstein B8 and Eibach on my previous E30.

I really liked it, but apparently Eibach springs are very soft, so there are probably many better options for track use.

Shock wise people say great things about bilstein 5100s, but I've got no experience with them.

I had a 2018 Z71 and went with the Rancho RS 9000XL Quicklift. Was a great setup. I now have a 2020 AT4 and put on a set of the Bilstein 5100’s. Don’t like them at all. Ride quality is not much better than the factory and I still have the rear end hop going over bumps at speed.
