Calling Koni Yellow and Swift spring owners

AH370Z

Hello, I have added front and rear koni yellow to my already swift spring setup and have notice the front is sitting much lower now. I did install front control arm bushes (upper and lower) the upper inner was double offset which gave me an extra -0.5 Neg camber so im probably running -2.0. Understand that may be giving an illusion to being lower due to tuck, however i feel like if it was running positive it would still definitly be lower than oem shock.
Overexposed some of the photos and added a red line to denote the top of tyre.

Rear guard is 688mm Front is 666mm (measure from ground)

Pretty sure everything is sitting right as far as the shock and spring

Appreciate the input. Also if you would like to share comments about ideal damping settings, currently running front and rear at 50% firm with a whiteline front sway bar in soft setting (approx 30% stiffer than oem) Do lots of high speed mountain/country roads everything from the rough stuff to nice and smooth. Want the sportiest ride while avoiding being kicked off the road if i do encounter a bad section of said roads.

Cheers

I run mine at 50%. Have the full SPL catalog, including bushings, and it rides more comfortably than OEM

Anyone else with this combo confirm? I have emailed Koni who have said they have sold hundreds of these with no issues with height. They suggested checking the bump stop condition however ride height was fine with swifts and oem shock

BettyZ

Did you do the install? Were all the parts put back on properly?

On the front Koni's. The lower spring perch is 1/4" lower than stock. So the front will sit lower a 1/4" lower. Commonly asked question about Koni's.

My mechanic did the install and I helped, all went on as it should.

Thanks Rusty, is there any official reference or evidence for this? other than me taking them off and measuring against the oem.

Email correspondence from koni are stating no height changes occure from shock.

Do we know if there is a solution for this? Can a spacer or similar be used to sit under the perch? I wonder if the G37 shocks sedan or coupe are different than 370z and Koni have matched it to them to save on cost. If the 1/4 inch is indeed true than Koni need to provide a solution to this such as an alternate spring perch that can raise it 1/4.

The solution is to get good coilovers

I measured them against the OEM and the fronts are a 1/4 inch lower - that's 6.35mm for metric-loving b*tch biscuits like OZ.

When did the metric system become “my thing”?

Maybe dont run a cheap spring/shock on a 500hp build.

The two 370's i drove with coilovers both rattles in the rear top mounts over bumps and just felt awful.

Might be able to get a claim for refund as per Koni's latest reply so may very well end up witha set of MCA coilovers if they can guarantee me they wont have the rattle in the top moounts Ive experienced.
