Powertrix Damping Settings Issues
 
Hello. I have a few questions regarding the Powertrix coilovers. I had these installed about a month ago and so far, they've been great and nothing short of amazing, but I'm having trouble with the damping settings.

The issue is with the adjustment knobs, as the clicks seem to be off on some of the shocks. Example, I thought I had set all dampers to a 7 level (7 clicks from full soft) but when I dialed them all back to 1 (softest), it took less clicks on some of the shocks and more on others to get back to "1". I then noticed that sometimes the click is barely felt and/or is very short or long, making it difficult to accurately dial them all in to the same number.

For now, I decided to set all of them to "softest" which brings me to my next question. Should I leave the dampers at this low setting? What are the pros/cons when it comes to spirited driving and canyon carving If I leave the shocks soft? should I compensate adjusting other suspensions components...like stiffening front sway bars, more neg camber?

BTW, The springs are Swift 12k front/11k rear

Mine are a little touchy on feeling the settings too, after a few times adjusting I got the hang of it. Adjust it to where it feels comfortable to you, for me all soft felt too bouncy to me, I started at 6 from soft and drove it for a few days and then started adjusting from there. I ended on 10 from soft on the front and 8 from soft on the rears

Can't say I've had that issue on mine, every time I adjust them they are where I left them last. I will say the rears have 1 more click than the fronts (fronts have 15 and rears have 16) not a big deal. I count from fully closed out so my rears are 1 click slower than front which should help with brake dive and rear wheel traction on turn exit (but at current settings for street I wouldn't push the car to where it matters). As far as having issues by setting them full soft your just going to allow the car to transfer weight faster in terms of handling as well as allow the wheel to follow the ground easier so it will be smoother over ripples and uneven surface etc. I suppose you could use the sway bar to counter the roll but it's still going to initiate quicker and too stiff a bar can possibly break traction sooner. Probably easier to just slow the damper down for when you want to actually have spirited driving, use the sway bars for over or understeer and just open the dampers up for day to day driving.

Thanks agave. Ima try some middle settings. Just gonna have to adjust each damper really carefully

Thanks for your input Jhill. What settings are you running?

I believe I am 12 out up front and 11 out at rear. I started full soft but that was way too bouncy for me and even got rebounded off my seat, however I think that may have been due to improper rear preload so I may try going softer as on some roads I could like it to be a little smoother (its not bad now though). so then I went 1/2 and 1/2 (I think it was 8 out and 7 out) I think I misspoke earlier when I said the rear has more clicks than front it may have been other way around ill have to count to make sure but for sure the rear is 1 slower than front. 1/2 and 1/2 was a big improvement but desired a little smoother on rough roads like 87 freeway so then went 1/2 of 1/2 (so went out another 4 and another 3 I think). now it feels very smooth yet still very damped but nothing jarring. I may give full soft another go now that I have the rear preload set right.

oh the track I was 1/2 of 1/2 going towards firm and it was awesome, so planted and never upset the balance of the car even hitting dips mid turn when I ****** up.

Yeah I remember you were going airborne and coming off your seat on every road dip :rofl2:

I definitively like a firmer ride... only thing I hate its when I hit slightly raised bumps on the road and the wheels make that horrible thump.

If it's the thump I'm thinking your are talking about then mine did that even oem and seems more dependent on tire, my michelins did it more than my Bridgestone. The thump like the sound a basketball makes type of thump? I think that's just the wide stiff low profiles, funny enough it does it less when I'm lowered and more neg camber (going to the track) then on my daily driver height and camber. Wish it was the other way around but that's physics.

Oh no... it was a loud metal thump. Well it only happened once but it was loud. I wonder if it had to do with the stiffness of the shock as at that time I was riding on 7 clicks from soft.

No I'm gonna say that isn't right. Should never have a metal to metal impact noise or feel over bumps, I would look around all suspension components for "witness marks".
