I have read in the forum that some pepole say that changing the diameter of the wheels from the stock offset of 26" front and 26.7" rear to same front and rear would affect the TSC. I always shut the TSC off, but i want the car to run ok even with it on. I have also heard that the ABS might be affected to some extent.

I am asking this because i will be putting 275/30/20 tires on 9" front and 10½" rears on my Z in the next few days, and there are no good combinations that will create the stock diameter offset while running same width front and rear tires on a 20" wheel.

FRONT SETUP
Stock: 26.0"
New: 26.5" (1.9% larger)

REAR SETUP:
Stock: 26.7"
New: 26.5" (0.7% smaller)

Does anyone acctually have any real experience or heard from someone who has of running same diameter front and rear and did this in fact impact the TSC and/or the ABS, and if so how much?


Thanks in advance for quick answers!! Most likely ordering my tires later on today... My wheels are sitting the the garage waiting... Cant wait to get them on the car!!!

As long as your f/r are within .72" difference from each other you're VDC will be fine. Should be no issue with ABS.
