lowering the rear
if this is in the wrong section please move it.
well i have a s14 with megan coils and i want to make my rear lower. but since the threaded shock body bottoms out against the shock mounts i dont know of a way to make it go lower. i know in the fronts you can take off 2 collars but what about the rear? i have like 6 inches of threaded part left but i cant lower it more cause it bottoms out. if anyone has any input on how to make it lower let me know. thanks in advance zilvians. |

You can lower it but you'd also have to tighten the dampening.. I'm getting Megan coilovers too I wish I already had them so I could tell you how exactly but I've never really got to play around with them before sorry.

what do you mean tighten the dampening?
you mean preloading the springs? because my problem is the rears do not have the hole (unlike the fronts) so i cant get it past the point its at right now. thanks for your input tho |

sorry I thought you were saying you could drop it but when you did it was bottoming out. That'd be the result of your car being lowered but not stiff enough to keep from full compression. Like I said that was the only thing popping to mind but I'm having to imagine the set up you're looking @ from memory of looking @ my friends once. hopefully someone with em will hope in here any minute now haha they're fairly common too...

because on my friends s13 he was able to remove the collars in the rear and actually go lower since the shock body itself is shorter in length compared to the s14. |

For the megans, once you hit the bottom of the threaded shock body, that's it. The only thing left is preloading the spring or getting a shorter spring.

good call cut springs freak me out. I've rolled in them before and just from the shape of them being off like the top never tapers out a good seat for the mount they tend to sit crooked and vibrate...at least these did so we had a super rapid metal popping sound and we definately got scared just driving to the store for milk let alone tryin to push them @ all on a fun road.

you can also get swift springs - a few of the vendors carry swift springs here; I think FRSport still carries them, but you have to call (not on the site).
I got swift springs for my megans. stock is 6", depending on how much thread you have left, you can go 5" or maybe even 4". I would probably just go 5" to keep a decent amount of travel possibility. Preloading the spring is usually not recommended unless used to corner balance a car (hence the invention of dual height adjustable) - you can search for more info on that; a little preloading doesn't hurt too much though. Going with a shorter spring will give you less total travel, obviously - so you will have a greater chance of bottoming out. Also, if you do decide to get Swift Springs or Eibach springs, you may want to consider getting a pair for the fronts as well - they feel totally different (as well as much lighter) than the ones that come w/ the Megans, might as well replace the entire set.

get a torch and get the coils hot and compress them
or buy some cement and pour it into the trunk of you car to add weight and lower your rear. Or pay a really fat dude to permanently sit in your back seat or trunk to add weight and lower the rear. Or raise the ground everywhere in the world and that would make your car look lower

You can see where in the rear coilover on the left, the black threaded body can only thread so far into the silver bottom mount before it hits the end. The fronts don't have this problem and you can just take out the locking collars when you want to go lower.

The only reason why rear shocks will blow, is if the shock is A) bottoming out, or B) operating in a range they weren't designed to do. Now, I know Stance GR+ will allow for some droop with no problems, as they were designed to do have a little droop in mind. The Megans... well I think some people have drooped the springs on their's a little bit and haven't had any problems, so it's really a "just do it and see" type of situation. |
