Will going from a 17" rim to an 18" rim change the alingment of the rear end? I am thinking no since we are changing the alignment of what the tire mounts to and not really the tire it'self.

However, I don't want to ruin a set of soft tires becuase I did not get the alignment done.

 

Sounds reasonable. I don't think it should cause a problem.

 

Once again I agree with Nathan.

Changing your wheels/and or tire size does not necessitate a wheel alignment. However, how long has it been since your last 4-wheel alignment? If it has been longer than a few thousand miles, I would spring for the 60-100 bucks for an alignment, since it is cheap insurance against abnormal tire wear.

That is what I am really doing. I just changed the Tie Rod end and Tow Link on the car. I am also changing rims and tires today. I want to drive to the shop for the alignment with the old tires and then go and get the new rims andres. That way I am not driving with a misaligned rear end with the new tires.


Here is what I am in the process of finishing up this week.

Removed Exhaust and installed a set of Headman Headers
Removed Frizbee
K&N Server
Rear Tie Rod Ends
Rear Tow Link
New Dist Cap
New Rotor
New Plug Wires (8mm Taylors)

Things to be done in the next two or so days

Alignment (Today)
New Tires (Today)
New 3" Exhaust from the headers back. (Tomorrow ??)
3" Random Tech Cats
3" Electric Cutouts
H Pipe
MagnaFlow Mufflers

While doing all this I dropped off one of my tires that kept loosing air. I Figured that it was a bad bead seating becuase the old tire\rim was filled with fix-a-flat. They had to clean the bead area with a wire brush to get the tire on. However, when they checked the tire the found that the rim has two pin holes in it. So.... I am moving the car from older saw blades to Z06 Rims that are 17" up front and 18" in back. Moving the 17" Koumo tires to the 17" rims and getting new 18" rims with new tires for the back.

With everything going on with the car I am hoping for a nice boost in power from where it was at.

Thanks for letting me know that I was on the right path with the Alignment.

 

Looks like you are spending a few $$$$$. I have my EM headers and pipes in the garage however, I am waiting until I get the cash for my LT4 Stage III kit from Scoggins before I do my install.



Good luck!!
