This is exactly what I was feeling in the car. either the suspension not compressing at all, or waaay too much. The metal rattle noise is an effect of shitty phone microphone recording. It doesn't sound like that in the car at all. There's no rattle at all. It's flat out solid bang over everything.
So a few new details to update. Monday night I pulled the redshift kit from the car and re-installed the factory suspension.
I managed to get it installed without any issues and it rides just like before- no noise, no rattles, no issues.
I am not sure what I messed up. I will say that plenty of folks have voiced either an install/config/or build concern and it makes me feel a little crazy because I have no idea. I followed several guides, I've watched videos for months now. I'm not a mechanical dumb dumb either. But who knows...
I bought all new bolts, I torqued everything to spec. I set preload on the springs at full droop. I even re-set droop at 5-10-15mm testing each time to no effect. I did find that the coil overs came on basically the lowest ride height adjustment which I requested at an inch. Even after adjusting them back up to the stock height the issue remained.
I made sure the strut body was fully seated, I re-checked all the bolts for torque or looseness. And I couldn't find anything obvious. The downside is, this was my first suspension install. Could I have unknowingly messed something up? Absolutely. I don't know what I don't know.
I've have had a number of individuals also voice concern over the dyno chart I was sent saying that maybe it's over pressurized or the rate is way too high, effectively saying that the suspension/dampers just weren't compressing at all. Which makes sense to some degrees because it felt that way. It truly felt like someone had just installed solid metal rods and that I was basically riding the Oregon Trail in a wagon. Mostly minus the dysentery.
- If I were to take more time with it I would have mounted my go pro somewhere under the car and got video of what was actually occurring. I regret not doing this now. I work in IT my whole job is troubleshooting. I wish I could have identified 100% what the issue was.
In the end though I may not ever know. I'm sending the kit back to Redshift and moving to significantly softer/lighter springs and street valved damping. If that kit is also like this then I've almost certainly screwed something up and I'll feel extra stupid and embarrassed. Even more so than I already do. Chris has been very helpful and accommodating. But the whole situation sucks. My first event is the 14th which is a test and tune and I'm almost definitely not going to be 100% ready for that. Which I guess is sort of whatever, I'm not trying to win. I just had my mind set on being "done/ready".
Anyways an alternate solution is coming. Once I get the new kit installed I'll update with results. Which I'm hoping are significantly better.
Also I appreciate the offer for a look. I'm in Ohio so I suspect that would be quite a drive
plus it's un-installed already.
Some folks had requested photos of the kit after I un-installed. I'm not sure I got absolutely everything or every angle or really even anything useful. I was in a hurry to get these boxed up and sent back.
FWIW I installed them exactly as pictured. Except I had the bottom adjuster ring locked into the correct position-on the bottom of the body to lock it in place.
