Why Shouldn't I Sag Springs?

[firelizard]

Hey guys

I've been searching for the past 20 minutes and I haven't found quite the answer I've been looking for...

What I basically want to know is why I shouldn't sag springs on my coilovers?

The point of doing it obviously would be to get lower, but what are the downsides?

I'd like as much info as I can find before I tackle that (or not), just so I know what I'm looking at.

Because if you sag or "droop" the springs you have less compression travel, which is already very limited on the front struts especially.

[SoSideways]

Usually people only droop springs for the rear dampers.

The fronts usually allow for people to go pretty darn low, on most of the coilovers.

just do it, no worries

^^haha damn.
i drooped my rear springs by half an inch and i thot i was BA.

wow...not a good idea...when it comes to your safety on the track or street just deal with a half inch higher or as the pic given 2 inches (jeesh). when you sag your springs your coilovers may not react in the way they were intended creating a dangerous situation. also sagging your springs shortens the life of the strut.

unless your all about taking your car to a meet and just showing it off. but if you want some performance out of your coilovers...(thats why you got coilovers instead of lowering springs i would imagine) set them up and use them as intended

shock can bottom out and make good things for your future!

[essforteen]

just install helper springs so the springs wont be loose when its at full extension

there's nothing per se wrong with drooped spring. droop and preload merely allocate between droop and compression travel.

it becomes a problem when you've reduced compression travel so much ur bottoming out the shock. some shocks also have set ranges where they are supposed to operate and blow if you move it out of that range. final concern is a uncaptive spring when the corner is unloaded, in which case you could get helper springs.

Thanks for the info guys, it's pretty much what I had gathered too, just from looking at other discussions, and a bit of common sense.

Based on this, I think I'll pass on daily driving like this, but it shouldn't be an issue for hard parking at weekend meets, right?

The car this is for is all about being low, no performance aspect at all, though the effects of the sag on performance I am duly noting.

Of course, the more info the better, so please, keep chiming in

if thats the look your going for i would suggest doing it right before you go and adjusting it right after. if your roads are nice and smooth then go for it but if your roads are anything like Highway 52 in san diego i wouldnt suggest it.

i had to pull the helpers off my tanabes and run that much droop to get them to be low (single height adjustable). mines a daily, spring never comes unseated on bumps and shit. the coilovers ride a lot better without the helpers, too.

Rear Koni Yellows w/ GC's 7" springs are the same way... the top hat doesn't touch the upper mount when the shock is at full length, i.e. off the car or when the car is jacked up.

Since the car's weight is always on the spring, you should be fine as long as you aren't getting significant air time, provided you are running stiff enough springs/bars to keep the rear planted. Also pay attention to shock travel.

lol the city we live in(same city :)) is garbage for roads :D half the roads have pot holes and going 2 inches is really pushing it so unless the car wasnt moving much(I.e not at all :D) I agree with you it wouldnt be too smart.

Hell, I have over 3" of "sag" on my front 8611's now. It's fine, just do it. The springs won't become unseated during normal driving.

[McRussellPants]

yeah, I've probably got about an inch and a half of droop on the rear.

gets twitchy when its really loaded down going over bumps because it'll make it to the bumpstop, but it doesn't really matter.

[tt99ol]

just do it
then if your still worried
put limit straps on the shock so the spring is always seated
then you can hit the jumps
no more worries

lol...so it doesnt matter when it is hitting the bumpstop?

very good point.

He doesn't care.

But it's horrible on the shock.
