      An alternate method that is also correct: let the spring free hang and set the shock height - then crank the preload into the shock after the shock is mounted into the car."
      So I experimented with the rears this morning with the current springs. Very straight forward procedure: All I did was remove the control arm bolt while the spring was supported by the jack, then slowly released it, and removed the spring. I then unbolted the bottom of the shock and turned it so it was extended another inch. Forgot about the auto leveling, but thankfully it not break. Put it all together and went for a test drive. All felt good. I left the spring perch position as it was, thinking that I would release some of the overloading, and the spring would push back up a little...

      Nope...adjusting the shock length did nothing. The ride height is still the same, the spring is still in the same compressed position and did not expand even a little, which leads me (and you others) to believe I need stiffer springs, since the current 5kg springs are compressed this low due to only weight, and I think any shock adjustment without stiffer springs will do anything to increase ride height.

      Do you guys see anything I did incorrectly or are my assumptions correct?

      I requested the new springs last week. I hopefully I get them this week.

      I really wanted to put on my summer wheels today. Maybe next weekend.....

      I know this contradicts what ORT is telling you man, but the spring is what sets the ride height. It carries the weight of the vehicle, not the shock. If you had a vehicle with springs and no shocks it would sit at the same static height as if it had shocks. It would bounce everywhere in motion (not to mention be insanely dangerous) but it would sit statically at the same height. A vehicle with shocks and no springs is going to go straight to the bottom of the shock travel. There's a reason you can compress a shock by hand but a spring requires a compressor.

      I hear ya.

      ORT is sending 7kg (390lbs) springs that are also 10" long, vs the 5kg, 8.5" springs that they gave me.

      FYI, the stock rear springs are 13" long, I don't know the spring rate on those.

      TBOMB is right.


      I looked at OTR's site. It looks like they re-purpose the same shocks for multiple applications just swapping out perches and mounts. I find this ironic since the only other product they carry are the best coilovers you can get for our cars (Ohlins). You should have a solid 2" of travel both ways on the shocks in front and back or they're too short for the application and you'll run into problems such as very short life. As far as your current perch setup, that's dangerous. I wouldn't run like that for a moment.

      What a debacle. As someone with a fairly custom suspension setup I'll say it. You should have just spent the couple extra hundred and gotten a set of H&R or Bilsteins designed for our cars. This thread doesn't instill confidence in OTR or their products. And what is with the threaded shocks the rear, guessing they're front housings which also speaks to OTR's product design.

      Thanks for your comments. I certainly have thought what could’ve been with a different non threaded shock set up, but it is what it is and I’m going to make it work, as they actually ride pretty nice.

      A closer look on the perch this past weekend, shows that I have over 3/4 inch of threads left, before I would consider it dangerous or not safe. Early on in the thread, I thought it was maxed out, but its not.
