I just got my alignment done. Two weeks ago, I installed my Eibach Prokits with Tokico D-Specs. It dropped a little over an inch. I have 19x9.5 +28mm fronts and 19x10.5 +23mm rears (Volk SF-Challenge).

Today my measurements are:

left right
FRONT
Camber -1.7 -2.1
Caster 8.2 8.2
Toe 0.04 0.04

REAR
Camber -1.7 -1.9
Toe 0.07 0.07

Will my tires wear out evenly? If not then I am going to buy camber kits. What are the factory specs for 19" rims not lowered? I want to see how close it is to stock. I searched on the forum but couldn't find the stock specs for a 05 6MT.

 

I would like to know the factory settings for an 05 coupe with the 19's aswell.

 

I have the entire 2005 g35 service manual, but it doesn't have the 19in wheel alignment specs. Here are the 18 in alignment specs:

Front

Camber
-0.5
range(-1.25 to .25)

Caster
8.00
range(7.25 to 8.75)

Total Toe In
1mm
range(0-2)

Rear

Camber
-1.25
range( -1.75 to -0.75)

Total Toe In
2.8mm
range(0 to 5.6)

The only difference between the 17 in and 18 in wheels is the caster otherwise everything else is the same. I'd assume that if you were inside these specs 18in or not you would be ok. The difference in the camber is to counteract road crown. The more the negative camber the more it might cause you to have more tire wear on the inside of your tires. With the offset being different it might change the scrub radius but an alignment won't adjust that. I'll try to check alldata tommorrow if I remember.

 

the -2.1 might show more wear than the -1.7 if you do highway miles
but with your toe-in you should be fine. the rear can use more
toe-in for stability. if the car feels fine to you, just leave it.
