So I banged my car up a bit...and everything is done, but the shop owes me an alignment...said they couldn't do it on my 10.5 rears and 9.5 fronts (295 and 275 respectively). So they want me to pop my stocks back on for them to align and then swap aftermarkets back on again. Question is this: Will the process give me proper alignment when my aftermarkets are back on? I'm running a totally different offset than stock...and the width of the tire must somehow account for the appropriate pitch/camber calculations, right? If I'm all wet...glad to hear it. If not...where can I get the aftermarkets aligned correctly? Do I need to request a specific kind of alignment equipment?

Any help/feedback is appreciated.

 

The wheels and tires you use dont affect the alignment (unless the wheels are bent).

When you do the alignment however, you should have any aftermarket suspension on the car as it will affect the ride height of the car. Meaning springs, shocks, aftermarket arms and such.

 

The rims and tires will make a difference as they are not exactly the same diameter as the stock setup. Tell the shop to pay you the money for the alignment and find a better shop.

 

How does the diameter of the wheel make a difference to the position of the suspension on the car?

When you do an alignment, you are adjusting the suspension arms on the car to give proper positioning of the wheels. The size of the wheels do not matter as you are not adjusting those.

 

Well...I don't know...that's why I'm asking...but it seems logical to me that all the adjustments remain the same...theoretically making the tire used of no consequence...but the diameter of the tire might make the readings more or less significant...in other words, a certain camber might be more acceptable with a smaller diameter tire...but then if you go with a larger, it may accentuate...that's kind of my thought on my wide tires...that what may be OK for stock might be too much for the wider tires? Again...someone out there has got to know this. It should be a simple question for someone who is a mechanic?
