Reviews of Bilstein shock absorbers

you can always put bilsteins on yourself (not too hard, put the 5100s and lift spacers/ blocks ((if off-roading, do not use front spacers, you will get coil bucket contact and a proper lift may be more expensive but its better on your performance and ball joints, i am mostly highway / town travel)) and it was done within a weekend with rental tools from the auto store).

I made my own poor man's B12 kit! Except mine is now complete with badged housings and early top mounts. No bump stops in the front and vestigial foam stops in the back. I went mild on the cutting. The rears could go up a lot or down a little without cutting. Excited to see how she sits. Took some before measurements for what it's worth.

Update, went with the Comfort (B4)s... and they feel great. Comfy.

Bilstein 5100's are junk! 3 out of 4 of mine failed. (Blown Seals)I don't even go off road with my truck. They won't stand behind them without original receipts, where purchased, when purchased etc. etc. etc.........

A little build up in a Bilstein is normal.

I would call it seeping more than leaking. These Bilsteins do that. Look at the grease/dirt under the spring.

Bilstein B6 monotube shocks work only with stock ride height springs. With a chassis as light as the IS300, they’ll give you a much stiffer ride than the other options. Some drivers like it; but you may worsen traction on roads in poor condition. Comfort will similarly degrade. Their main advantages are that they won’t fade in prolonged aggressive driving and they last a long time.

Went with bilstein b4’s and eibach pro kit. Couldn’t be more happier

You can try new shock absorbers and springs in the back to start with, youll gain a bit of ride height and bounce control, make sure to avoir super cheap brands because they are not worth it, stick with Bilstein/kyb/sach/mando/ for shocks

B8 with lowering springs was the sweet spot. Less roll, squat, and dive with a controlled & comfy ride.
