Hi all -

I had it with the wheel hop I was getting so decided after reading about everything I could to do the following;
1. New Rear Springs - 55D Spring Kit (although not required while I was there I thought I'd replace 'em
2. Ford Racing Boss 302S Lower Control Arm Relocation Brackets
3. Adjustable lower control arms

I put everything in, adjusted the control arms to equal length and drove it. The steering wheel now is about 15 degrees off center.

I ordered an adjustable panhard bar which I should get on Monday but will that correct this or am I looking at an alignment???

Reason I'm a little upset, the 55D guys are spouting that "No alignment required after installation".

 

how are rear suspension parts affecting your front end?

 

If the lower control arms are adjustable then yes it needs an alignment. Actually will need all four wheels to be checked and adjusted. Let the alignment technician know about the rear end modifications so he can get it all straightened out for you. Chances are your car is dog walking slightly right now.

 

Those springs only lower the rear half an inch so you don't need an adjustable panhard bar, relo brackets, or adjustable LCA's. The only thing that could have affected steering is misadjusted LCA's. You'd have been better off with nonadjustable ones.

 

Front adjusting to the rear being misaligned.

 

Probably without adjustable arms, when you adjusted the length did you line up the old arms with the new or just adjust them to be equal length?

 

I adjusted both bars to be equal length.

Concerning adjustable vs non, I don't think you can add the lower control arm extensions w/o adding length to the control arms since the pickup point has now further away than before.

I just measured side to side and found that it's about .25 inches to the drivers side in other words it'd take .125 to the passenger side to be centered. Don't know what factory specs are.

Sounds like my best bet is to take it in and have them do a 4 wheel alignment to be sure.

 

This is why adjustable lower control arms are not necessary for the majority of us. if you don't get it right your alignment is off.

 

Is this a rhetorical question? Many ways the rear suspension can mess with your front.

 

Sorry bud, but I think you ****ed up. You want the new LCA's to be the same length as the old LCA's not adjusted to be the same length as each other, also you don't have to add length, the pumpkin will tilt on its axis and bring the brackets towards the front when lowered.

 

Just remove the arms and adjust them to exactly the length of the stockers and you should be fine. I CERTAINLY would do this before going to an alignment shop.

 

I have 55d rear springs in my 2012 gt along with a roush uca and frpp lca,the wheel hop went bye bye and my front end alignment is still ***** on perfect,did not effect the front end at all.

 

When you do it right that will happen.

 

Gotta love somebody who blames the springs for an alignment issue when he installed adjustable LCAs. These are pretty much a waste of time and effort on springs with that little drop...or ever for that matter. Doing your adjustments up top is way easier and never requires and alignment.

Relos change the position of the hole so you don't need adjustable LCAs even when installing these.

 

Not nice. Only way to learn is to do it and not pay a shop like most of us do including myself. He turned a wrench 1 cm more than I will when I drop mine, so props for that.

 

You misadjusted the LCAS like previously stated. I did the same thing once

 

So, with those mods, did the wheel hop go away?

 

Here's the latest -

Pulled out the old LCA's and measured center to center (18.5 in). Readjusted to 18.5 center to center along with installing the new adjustable PHB. Everything seems to be back in line again.

How is the wheel hop? Still there. I now have a noticeable increase in interior noise now from the LCA's. I'm a little surprised they're that noisy. Any additional ideas on calming down the wheel hop?

I agree. Look at the one from Roush. I believe it isn't as noisy as most others.
