alignment setting

johnsonz1122 · 12-15-2014, 08:12 PM

i drop my car on bc racing coilover about 2 months ago.
i went to the shop for an alignment.
after the alignment my car is constantly pull to the right.
i know must road are crowned, and car suppose to pull the right slightly.
but my car pull way too much, it's like it's turning to the right all the time.
can you guys help me take a look at my alignment spec. see if there is anything wrong?
i have notice the caster angle is slight different, left is less positive than right.
but i thought the car suppose to pull the less positive side.

please let me know what do you guys think

If the car never pulled to the right before you did the alignment, then it's time to redo it and see if it changes.

If the car did pull to the right before, then maybe it's similar to my issue:

It pulled straight out of the factory and even after three alignment attempts it still pulled (slightly) to the right.

I was running the Brigestone Potenza S001 run flats.
Front: 225/45/R18
Rear: 255/40/R18

I recently changed to winter tires, non run flat, (Michelin Pilot Alpin 4) and the car no longer pulls to the right.

Upon inspection, the outer wall of the front right tire was worn out significantly more than the other tires.

I could only keep the two back tires after less than 10k miles... (just "normal" driving - no track days)

The dealer attributes this to my "aggressive driving", but I think that I just got a batch of shitty tires.
I'll wait and see how this will fare on the new winter tires.
Let's hope that the problem doesn't come back, or else I might have to change dealer due to incompetence...

So yeah, IMO it might also be that the tires are to blame.

even with new suspension you should not have a hard pull one way or the other. One way to test for it is to find a parking lot with level pavement and drive there. the other thing you can do is look for obvious wear on the tires

it been resolved,
the shop did another alignment for me, and it's fixed
thanks for the input!

Is the toe angle different now?

A left toe angle of +0.4 and a right of -0.25 means both wheels were pointing to the right.

Curious, how much did you lower the car? What are your new alignment specs? I am very curious if after lowering a bit if the car can be aligned back to factory specs. I plan on getting some coilovers for my F36 once something is available and doing a conservative drop of somewhere around less than an inch. I still want at least 1/2" of gap between the top of the tire and the fender.
