That's pretty much the sweet spot for standard Konis. As you approach a full turn they get very stiff.

FYI: 2.5 turns from soft is full stiff.

I'm running Koni Yellow's and H&R Sport springs and had the ride set to 1/4 turn from full soft in the front and 1/2 from full soft in the rear. These was too stiff for me for daily driving (nice for spirited driving though!) so I dropped it to full soft in the front and kept the rear at 1/2 from soft and comfort seemed to improve a bit.

Ride height for me is about perfect (about 2 finger gap) although I do cringe whenever I'm about to hit some uneven surface as it seems to be pretty harsh. Not sure if it's as bad as others with this same or similar setup. Zero rubbing anywhere.

Rears must be set "softer" than fronts?

To adjust the fronts wheels must be off the ground?

They were TCK Koni yellows, but they're not built to a different standard-- just valved differently.

That said, the Koni yellows in my M5 are at 90,000 miles and haven't needed to be adjusted at all, and the Koni yellows in my mom's e46 325xi are at 130,000 and haven't needed any stiffening.

Konis are a long lasting shock! When I pulled the TCK Konis I had them put on a shock dyno to see if they needed to be rebuilt-- they didn't.

Only super high end race shocks have 10k lifespans.

Yeah, you want the front as soft as possible (spring rate and valving) for best street manners - the front should glide while the rear keeps the chassis poised. This is opposite a "performance" setup which stiffens the front dramatically relative to the rears. The catch 22, though, is that low and soft don't work well together so it's a fine line.

Your car hits hard due to lack of front travel. These cars have roughly 2.5" of bump travel at stock ride height and you've probably used up a least a full inch just sitting still. Restoring travel would help immensely over the medium/big stiff but the small stuff will always be firm simply due to the spring/shock combo itself.

why does Dinan recommend so much adjustment on the rear? I think they recommend 1 3/8 turn on the rear whereas front is 1/4 turn.

Rears are typically setup stiffer than the fronts

I was just going to ask what is the recommended setup for a Dinan stage I shock/spring setup?

I'm the second owner and it had this setup on it (Dinan stage I), it has got softer over the years was wondering where I should set the shocks at?

Smile Re: Suspension - Koni Yellow (what springs & settings?) E46 M3

Installed them today with my ACS springs.
I need to correct the alignment.
Also installed my stock front sway bar.
Did around 20kms and Iam very happy with how they absorb imperfections compared to my previous shocks (ACS) and the H&R front sway bar. Handling is also very nice. Minimal body roll. Very happy with the outcome.
I set them at full soft.
