Alignment problem
 
1 Attachment(s)
Ok so I just installed a set of tein s tech springs (used) and z1 spacers 20mm/25mm and I also bought tires and got an alignment. My car now shakes when going above 60 and my alignment is WAY off need opinions..... I think I might take the front spacers off to see if it fixes the shakes and if it does then I can guess that's why my alignment is so off aswell but idk help lol

Vibration is not caused by your poor alignment. Did the shop even try to adjust the rear camber?

You said you got new tires, did you get them balanced? Take them back to the shop that did it and tell them its bouncing and needs to be re balanced. That's why its shaking.

As for a alignment, holy cow that is messed up. positive .9 front left and negative 4.5 front right? Something is seriously wrong for the alignment to be that bad. Maybe you didn't seat the springs right?

Honestly it looks like they made the rear worse after the alignment and the front is just terrible. The springs were installed fine idk I'f it makes a difference that I didn't let them settle? They were used but the forum member said for only about 5k.I'm gonna rebalance the wheels at my job today and see if it helps . But the alignment has me worried

This is the pre alignment specs

The only time that alignment will cause vibration is if it is WAY off to the point that the tires are slipping. I mean WAY, WAY off. Alignment problems result in the car not tracking straight or steering weird and uneven tire wear.

Vibration is caused by either the tire not being in balance or not running true. Improperly installed spacers can cause the tire to not run true which leads to vibration.

Make sure that the person that balances your tires calibrates the balancer before balancing your tires. I've seen this problem a bunch of times.

If the spacer(s) isn't sitting flush against the hub face it might explain the funky alignment numbers and the vibration.

Rebalanced all four tires and took off all of the spacers, drives fine then when I hit sixty boom still have the shakes

You could have a hub bearing going bad,,,did you do all of the install-or have it done? could have some severely worn part's.
Also,that one front wheel w/-4.5camber should visibly be leaning about 1.25"inward....That's where i would go first;and if you're not noticing a huge difference of wheel lean left/right, then i would have to question the guy who set it up on the rack.

jchammond 07-12-2016 07:18 PM

Looking again at your chart-the other side is leaning out about 1/4"....?
something terribly outta whack.....

nis350 07-12-2016 10:07 PM

so the only changes are the springs and new tires. assuming everything was ok before, I would check to ensure everything is put back correctly and perhaps have another reputable tire shop to balance the tires again.

Have someone check for lateral runout of your wheels first and then the tires while on the car This should show what the problem is. It does happen that a new tire is defective and this can cause severe vibration. Good luck with you repair

TBatt 07-14-2016 09:09 AM

Stansens is correct, don't rule out a bad tire. I had a bad tire on my last set that the installer said he didn't like the way it looked on the balancer but it did balance. He recommended that I drive it a while and see if the tire settled in, it didn't. Tire Rack sent a replacement and everything was fine after that.

Good luck!

Thank you very much for all the help, I haven't had much of a chance to mess with it due to working a lot but I do not feel any shaking anymore. There is no visible slant on the front right vs the front left so I'm going to get it aligned again. I installed the springs with the help of a mechanic and there was no visible ware on any parts other than the toe arm bolt was stripped and replaced, the car is at 112k miles though. I'll update when I get aligned and pray that my specs are a lot closer to stock

Halfkiddio 07-18-2016 12:30 PM

My hubs were failing at 102k miles. That could very well be your issue. I replaced the front pair and a vibration at highway speeds I had went away.
