so I'm a sedan on the Eibach PK, stock wheels on 20mm spacers on all 4 corners and the GTspec brace. After dropping the car, everything felt solid & precise...even though I knew the alignment would be out of whack a bit, the car felt good and tracked straight. So knowing that I had to do the alignment to ensure better tire wear, I did just that this past weekend at a recommended "precision alignment" shop (unfortunately while visiting family in SoCal while I live in NoCal....dumb I know). He told me that things were pretty far out of alignment (toe/camber) which I expected so no big deal....asked him to get it back to as close to spec as possible which he obliged and did while showing me the printouts. HOWEVER, now the car feels kind of shifty. Hard to explain, lots of sway in the a$$-end which wasn't there before. Feels wiggly in a spirited lane change and cornering which is unsettling. Just doesn't seem to handle as well and the "slip" light seems to come on through quick curves which it didn't do before either.

Did having him dial it in as close to factory spec screw things up & was that a mistake on my part? Need to remedy this asap as I have an HPDE track day coming up next month.

Advise from those that truly have a grasp on proper alignment?

Much appreciated......thanks in advance.

 

Scan and post your alignment printout.

 

i have the PK on the coupe and my alignment is in specs and i drives a lil better than before
so please post ur alignment specs or go back to the shop

 

I've got the data sheets and will scan & post them up tomorrow from the office. I can look at them all I want....but I have no idea what the hell they mean.

 

where you got it done at?

 

Where did you get it done and what are the specs?

What were the specs before?

Perhaps you actually have MORE static grip, and the VDC can't cope with it?

 

"Kevin's Precision Alignment" in Camarillo....not doing it close to home was a huge mistake on my part.
Camber is now this I think...
LF -1.6 / RF -1.6
LR -2.8/ RR - 2.6

 

Mine was the opposite it felt all out of whack after i lowered it but it felt perfect after alignment so thats weird that yours feels this way after alignment

 

should post up your toe spec's. camber won't cause too much driveability issues

 

im not an alignment expert by any means but my coupes camber is -1.6 and -1.5 in the rear so yours has a lot of camber. dont think its different from sedan to coupe but i doubt it

 

Toe:
LF .14 - RF .15
LR .21 - RR .22

 

look at the paper, does it show a green light? if i remember correctly my last alignment was set at 0.07 for the rear toe at - 2 camber

 

Ok give me a few....just walked in the door and got mobbed by 3 kids and a pretty lady all vying for attention. Haha

 

Too much negative camber and too much toe in.
That guy did nothing.

You need at the least rear camber arms, and toe bolts in order to get the alignment close.

 

Ok so camber numbers are I'm red boxes at the #'s I listed above. Toe numbers are all green. Caster FL is green at 5.1, RF is yellow at 5.4.
