Ima try an make this as clear and short as possible.

Setup:
Front Koni/GC 300lb(Both sides, checked)
* New konis on each side (All the way firm)
Custom Extended Top hats

Driver Side:
UCA hits shock tower.
When collar ring is moved up the car is raised almost to pretty much no tucking tire. At this point it doesnt smack.
Once collar ring is lowered to a height of tucking any tire the UCA hits A LOT!

Now where it gets confusing

Passenger Side:
UCA never really smacks
The collar ring is as tight as i can get it & it still tucks half the tire.
Its as high as it will go.

So basically i cant even get my suspension even at its highest or tucked point without the driver side smacking. IT doesnt matter if im in the car or not btw.

Things im pondering:

The knuckle on the passenger side has quite a bit of vertical tension when moved up and down by hand, were as the driver side has more forgiveness when moving up & down.
UCA bushings that connect to the chassis?

Stiffer springs. Going to 400lbs. Yes im sure that will solve my issue but still doesnt explain whats happening.

 

When you adjust height, you need to either get the entire front of the car off the ground or disconnect the swaybar. You can still go higher, and level out the car as needed, if you go ahead and preload the springs lightly.

Both 300 and 400 springs are way too soft to tuck tire and not have issues, assuming that we're talking about a pre-01 Civic or Integra.

You should probably tell us what car is being discussed, btw.

 

Car is always raised off the ground when adjustments are made.
BY preload the springs you mean tighten the collar up to make the springs compressed while the car is jacked up. Did that. & it did raise the car enough.

This is a CRX si with stock A6.
i figured 400lb springs would be plenty.

 

Sounds like a problem with the upper UCA. Did you try moving it up and down with the knuckle disconnected? Are you sure both UCA's are correct for the car and are on the correct side of the car? Are you sure both knuckles are the correct for the car? Some Honda knuckles (such as DA knuckles) are taller than others and can cause clearance issues.

Are you 100% sure both front springs are exactly the same? Something definitely isn't right if you put both spring perches as high as they will go and the right side still tucks half the tire and the left side does not.

What I would do is jack up the front of the car, remove the wheels, and then put jack stands of equal height underneath both front LCA's, as close to the back side of the brake dust shield as possible, and then drop the car down onto the stands so that the suspension on both sides is loaded. Then take some measurements such as lower fork bushing to upper shock mount, fork bushing to spring perch, etc. and compare both sides.

 

are you on stock uca????

are you sure you have the right spring height front to back???

 

Disconnected so that the axle doesnt play a roll in the weight to the knuckle? no i did not.
They are def. correct UCA & forks as i have EF koni's which hug tight, were as DA knuckles would allow plenty of play for the shock shaft to slide in and out of.

Positive on the springs as well. TOok them off same number on both of them with the number coming out to be 300lb springs.

I wouldnt be suprised if it was the UCA bushings not giving any tension on the UCA but i just wasnt sure if that could really make that big of a difference. I mean that dont look cracked or anything to the eye while on the car.

Also i did put jack stands under the hubs and see what was going on. THe passenger side i could fit my fingers on top of the UCA between the shock tower telling me the passenger was not just sitting on the shock tower

 

Anyone else wanna pitch theyre .02?

 

can you take pics?

 

^ yup. Ill see if i can get some today

 

I kinda skimmed so sorry if I missed something have you check if the knuckle is bent or either side is set back and binding. Lca have any damage. Get those pics up.

 

Kinda over this. Between my other thread on another forum. Done trying to figure it out just gonna fork out the extra $ for stiffer springs when i get the money.
