Lol hey he's an engineer, engineers have to take everything into account.

But on the side note would you be able to do that for me? How much would shipping cost to 11580? Thanks!

 

Believe me, I'm not. I understand what you're saying. However, if the rear shock is blown to such a point that it causes a misalignment in the suspension component, it can cause one side to sag. I've seen it (much to my horror) and I don't know how the hell the person kept driving the car safely. The more I think about it though, the more it appears that this car's suspension is a lot more sensitive to anything being off and would easily cause other issues. So I'm thinking you are right, spring is the more likely culprit.

Mine is a sedan, but I went out and measured on a slight incline and the gaps are pretty even on both sides. I can't help but wonder if a visual inspection of the tire was also done. I.E. same pressures, tread wear, same tire size, etc. as you pointed out. I don't know if the springs are painted or where the likely fatigue/stress points are, do you know? Generally though, you can look for stress fractures or see if part if the spring is more compressed than the rest of the spring. If the spring is evenly compressed and measures at a lower height than the other side, then it's definitely worn.

OP, can you check the tire pressure, tread wear, tire size, etc? The other thing you can do while not accurate but will give you a ballpark, is to jack up the rear again and measure the rear spring heights.

 

Well last night I jacked the rear up and removed both tires and visually I didn't see stress fractures or fatigue. The springs looked decent to me but if ScraggleRock is willing to send me his springs then I can compare the two and see if there's anything going on there.

As for the tires, both tires are the same with the same pressure and both are the same OEM size. When I lifted it rear, I measured the distance from the tire to the ground and both were the same distance. I didn't measure the spring though but I will do that tonight and see if theres any difference.

I am, however, starting to believe it could be the shocks as whenever I drive it through let's say speed bump, the rear tends to just drop suddenly to the ground. Again I have no clue when it was last replaced so I'm starting to believe it could be that. If ScraggleRock sends me his springs, and I get replacements for the shocks, then I guess I will truly know. If that doesn't cut it then it has to be something else in which then I would have to take it to a shop.

 

Also, if I were to replace the shocks, which shocks would you guys suggest I go with? Nothing adjustable just fixed shocks. I see the two most common ones are kyb excel g and tokico HP blues. My car has the sports tuned suspension package and everywhere I look to purchase HP blues, it says not compatible with STS. The kybs, however, have ones compatible with STS. Do you think I can still go with the HP blues or should I just go with kybs?

 

If the shock was majorly blown, you'd see it easily. It sounds more like the spring could be worn. You need to measure the spring compressed and uncompressed and compare to the other side. this will help you figure out what the issue is.

As for shocks, the KYBs sport will give you the nearest OEM feel without breaking your wallet.

 

Yeah, I'll send em to you, no prob. I got nothing to do with them. I am in SoCal tho, and I don't know how heavy these are. May cost like $50 or something to 11580. I'm in 91978.

Also, they have 105k miles on them. They were still perfectly fine when I took em off, but if yers are gone at 140k, I don't know how long they'll last. Yours could be defective, or that may just be their life, I'm not sure. Anyone else know how long they normally last?

 

I'm on the boat that this is a sagging spring issue. Springs wear, and I've dealt with a few cars with separate spring/shock combos in the rear and 99 times out of 100, it's the spring that has just worn and started to sag.

That 1 time however could be worn/busted bushings and such causing that side to droop.

 

Well if yours has around 105k, then i would assume theyd get shot soon as well. Did you have any issues with them before you took them off?

Well i am now looking for springs but cant find any OE like springs. Only springs that are out are lowering springs. Maybe i should go for the TEIN High Tech springs since it only has a 0.6in drop in the front and 0.3in in the rear?

I already ordered some shocks, thinking of replacing them regardless if thats the issue or not. Thinking about getting springs and oem springs are like 170 each whereas the tein high techs are 190 for all 4. Do you guys think it will be a good replacement for oem and match well with kybs?

 

No issues with them at all, no.

 

Alright sounds good, I just got my shocks today and going to install them tomorrow first thing in the morning. Then i will truly know if its the shocks (which it probably is). Hopefully you'll still have them around by then.

 

I will. Just PM me and lemme know

 

Yup its definitely not the shocks, looks like it the springs. Should i just go ahead and get tein h techs for all 4 or should i give your rears a shot?

 

Just changed the springs, and my passenger rear tire is still rubbing with 25mm spacers. its not rubbing as much as before but it still rubs. this sucks, i thought you could run 25mm all around on stock height without having to roll the fenders.

 

SO that corner still sags?

I wonder if you have a bushing or some other issue causing the sag?

 

Yeah it still does a bit. At least enough for the tire to rub against the fender when turning or hitting a bump. I have an appointment tomorrow to get a wheel alignment done since i replaced the shocks,springs and got new rear tires. I'll ask the mechanic when he has it up to see if he can locate the reason why it's still sagging.

Could there be anything else, aside from springs, that could possibly affect the ride height?
