Here's my alignment sheet.

 

That actually looks pretty good. I would have them back off the ball joints enough where you don't rub and see where you end up. You still have a lot of room for adjustment. Get the SPC kit for the rear and you'll be golden. Each full turn of the ball joint into the arm nets like .2 - .3 degrees of adjustment.

 

I have this "thud" as well. It seems to happen over bumps and at full steering lock.
I'm lowered on BC coils with -1.9 camber Front

What are my options?
More negative camber?
Massage the fender for clearance?

I'm having my mechanic do some work in a few weeks and I'd like to resolve this issue.

 

Sounds like compression rods to me. Gdirty can probably shed some more light. Have you changed your comp rods and if not how many miles are on the originals?

 

Hey, bchalks, I think we can rule out comp rods since you installed the ones I sold you. Haha here's a list I made to help with finding your thud:

Also, how come you're running 1.9 degrees of camber? Shawn's numbers are pretty perfect as far as cambers concerned.

G-Ryde, I'm on my phone and that pic of your alignment numbers is super small. What are your camber numbers? If you have the ball joints pushed out too far, that could be your problem.

 

Let's try this image before I retype all of it...lol

 

Running some more negative camber will pull the ball joints away from the inner fenders. Right now your at -.1 and -.5, you have lots of room to pull them away from the inner fenders before you go out of specs. Simple

 

Sweet!

 

Whooaaa, -.1 and -.5? (The image isn't working for me, but I'm assuming by what Shawn said, that's what it is).

Yeah, that's way too positive. You'll start wearing the outside of your tires. I would run between -.7 and -.9.

I run -.8 passenger and -.9 driver.

 

Gdirty - I'm running the comp rods/bushings you sold me and kinetix arms. Currently at -1.9F but wanting to go to -2.5-3 for handling reasons. Don't care about tire wear.

Will the extra negative camber fix the "knocking" issue I have? Or do I need to do fender mods?

Edit: just read your response, only running -1.9 because I didn't have time to readjust the arms.
How do I fix the ball joint problem if they are out too far?

 

Camber shouldnt be causing clunks and thuds.

Did you grease the bushings on your UCAs? Also, I would check the nuts on those compression rod ball joints. I didn't tighten mine down enough once and it caused a gnarly clunk. Also, check your steering knuckle ball joints. If they're leaking, that could be your problem too.

 

Didn't grease the UCA bushings (I think).

I will check the comp rod nuts.

I first noticed it when pulling out of a parking spot (parallel spot) at full lock and heard the clunk. I have a feeling its not a loose nut (trust my mechanic) but rather a random clunk.

 

Yeah, if it came up right after the install, then I'll bet its that nut. Also, make sure the subframe is tight as ****. I think the bolts on the ends of the subframe (the two 19mm bolts) are supposed to be some bullish!t like 160ft/lbs.

 

Cool. I'll make sure those nuts are tight and re-asses.

 

OK, let me be clear here because I was talking about the subframe, and I don't want you to try to tighten the comp rod ball joints to 160ft/lbs. Haha

Comp rod ball joints: tighten tight. Use best judgment. Not sure the specs.

Subframe bolts: 2 - 19mm (they may be 17mm) bolts 160ft/lbs, all other 14mm bolts I believe are 65ft/lbs
