Do you have any recommendation of 14mm lower camber bolt vs 16mm upper camber bolt?

Alternatively, most cars do not have perfectly centered subframes, which can result in a slight deviation left/right, but not as much as shown in the previous picture. |

Just got these babies installed in my BRZ this weekend and like them so far!
Will post a more detailed review when I get alignment and corner balancing. Does anyone know what's the correct way to set the spring preload on these coilovers? I might have moved the top collars a bit while adjusting the ride height; would like to just re-set the preload on all the four springs. |

How to "measure preload" is exactly the part that I don't understand. How should I do that?
Not sure by "isn't loaded by other components" mean, can you please elaborate? Would lifting the car on jack stands and taking off the wheels suffice? |

They measure the compressed length of the spring and compare it to the free length of the spring to measure pre-load. iirc this car lets the suspension hang to full droop unless there's a bound up swaybar or bushing. Some cars/suspension designs do not allow the damper/spring to travel to full droop when lifted up into the air, some do.

What is the desired difference in length between compressed and uncompressed?

Should be quite minimal. A 6k spring should not be preloaded very much if at all. When I used preload adjustable coilovers, I tried to stick to zero preload(I was running 9k rears), ie only tightening the spring collar until the spring was tight and not allowed to move around side to side when at full extension. The more preload you use the less you will allow the wheel to travel down(droop) which is not preferable. An easy way to measure this is to measure the spring length at zero preload and make sure that length is the same when you tighten the collar up against the spring. Unless you are running out of compression travel(not enough room before engaging the bump stop), you should set preload to zero to allow maximum droop travel. Use the shock length adjustment for setting your ride height. If CSG staff or anyone else feels I am incorrect in what I've suggested, please feel free to correct me.

As you know, these are very adjustable systems and is meant for the end user to dial in to their desired requirements and application. That level of freedom is what makes end users like our product more. Those adjustment knobs help adjust damping characteristics as well. Believe it or not, there are people who complain to us about systems without ever spending the time to make adjustments (ie: not using the knobs to adjust damping characteristics, etc.). |

Given that at this point I've dialed in everything else, for now I'll keep the preloads as is, hoping it was haven't altered them too much. Maybe I'll come back to that next time I do corner balancing. Quote:
The installation instructions don't mention anything about preload. They do provide the spec of the length of the unloaded springs on the last two pages, but one needs to be pretty proficient with coilovers to know they should look there. I'm also not sure if measuring spring length is reliable enough, it seems that something like "one more full turn after the spring becomes snug" would be a bit more precise. For comparison, this video from FactionFab is amazing: [ame]https://www.youtube.com/watch?v=4BNt36sNOTU[/ame] It explains how things work (in a way even dummy can understand), how to dial everything properly, and even provides a table of coilover length vs typical ride height, accounting for the suspension geometry. And it's less than 5 minutes long. Don't get me wrong, I'm overall really happy with choosing CSG TEIN Coilovers (more detailed review will follow in a few days once I come back from a track day). But the supplied installation instructions have so much boilerplate, and yet insufficient actual instructions (or even misleading!) that when I got help from more experienced car guys we basically ended up installing "how we see fit", only checking the instructions for torque specs. If FactionFab can casually explain so much in under 5 minutes, I'm sure you could explain the installation and basic setup in 5–10 minutes too. |
