GU5 is for 3.23's and GU2 (i think) is for 2.73's, if you don't have the GU5 code, and your an auto, you dont have the 3.23's

i know some wheels that came on z28s and non ram air TAs and formulas, were the same that came on the v6 models which had 235/55 16s.. so if your car came with those, they werent zrated, and therefore governed.. maybe its possible that the most basic z's and birds came with that package or, without a package i guess you would say

First, all 02 Z's did not come with speed rated tires (that is true for all years).

I'm to lazy to look up the actual numbers right now, but, the story is this: most cars (90%) are ordered by the dealership on speculation as to what they think the buyer will want or fleet buyers. The production numbers show that out of about 24,000 V8's ordered in 02, only 4-5k were ordered by the actual buyer with a downpayment. The rest were ordered by dealers.

This is why there are any 115 mile speed limited cars at all. I really doubt that any gear head would order the base tires.
