Looking through online GM parts houses, I come up with two part number for a front leaf spring on a 2007 Corvette with an automatic transmission.
15233399 - RIDE & HANDLING SUSPENSION
25962574 - SPORT SUSPENSION
Those descriptions use unfamiliar terminology. I have is a Z51 optioned Corvette. I know this as the "performance handling package." Tirerack gets that right so how in the hell can GM's part # descriptions screw it up so badly? Anyway, I would guess the "sport suspension" is for the F55 option (magnetic ride) and the "ride & handling suspension" is for the Z51 option. I'm sure someone here will chime in and be able to tell me what part # is the correct one for my car, but could anyone tell me how I can independently confirm this? Would the dealership be able to see RPO codes vs GM part numbers? Is there some sort of secret description cross reference compatibility of which I'm unaware? Would I have to find the part number on the spring itself?
IMO, whoever designed the whole part number/vehicle lookup methodology and approved these descriptions needs to be fired. In this day and age, I should be able to put in specific RPO code options, at the very least the common ones that affect consumables, and have only the applicable OEM part numbers appear.

Instead of RPO code use your vin number on gmpartsnow.com it's the last link in this list. I Google C6 Corvette leaf spring and came up with these three, but very spotty descriptions for all three. I imagine even dealer parts Dept has a hard time decoding this mess.

Every time I go to the dealer to buy a part the parts guy asked me for my vin number. He once told me if he has the vin, he can give me the exact replacement part for my car so I keep my vin number in my wallet.

It's the other way around. "Sport suspension" is FE3, which is one of the RPOs that happens when you select Z51 on the order sheet.
"Ride and Handling" is FE2, which you get with the F55 RPO.
The part number required may differ depending on what combination of RPOs you've got, so it's not as simple as specifying a "Z51 spring."

Yes. The dealer will have a parts list, and it will look like this:
I just replaced my front spring. 2008, Z51 option, M6 and my part number from GM was 25962573. Had to have mine shipped from Wisconsin which took an extra dat or two.
Yep, the Fe1, Fe2, and the Fe3 spring sets come in two flavors each,
being one is for the M6 trans, and the one for the A4/A6 trans being slightly stiffer than the one for the man trans in the FE1, FE2, and FE3 trans spring sets.
Not understanding catalog doesn't make it the problem. The new OEM parts catalogs are in a sense driven by VIN. When VIN is used all installed RPOs are used to select correct part. Dealer installed don't should up. VIN filter can be turned off if necessary normally because of color obsolescence. In the old day someone would be under car looking for spring code number, or paint codes.
There is a cost advantage with online purchases, as long as you guess right part.Local dealer may cost more, but lessen the chance of receiving wrong part. Also they should be easier to deal with when part doesn't match what was requested.
I've tried going to the dealership parts guys but they can't seem to give me any answers outside what's on my VIN (See attached). I love to autocross and am slowing upgrading my car. I have an FE1 suspension to which I've already upgraded to Z06 shocks and Z51 sway bars on my base 2013 Coupe with the automatic transmission. So, What upgrades are available for my car? I would think that the Z06 would be too long given the car is wider stance so that leaves me with the Z51 (FE3). After reading this thread I'm now confused as to what parts to order. Can someone clear it up for me?
Manufacturers move to vin specific parts ordering process to reduce wrong parts. The GMPP catalog lists what performance parts available. Some parts people are more knowledgeable than others. Gearheads usually are more knowledgeable. FE3 consists of more the springs, shocks, and bars. You really can't add it easily without a donor. Z51 came in both base and widebody. It depends on budget. Z06 control arms have stiffer bushings. Z51 springs will be stiffer than what you have. So used part shopping. There's always someone selling suspension parts in autocross p&w. If you plan on class driving I would talk to people who know the rules in the class you plan on driving. You should post a new thread in C6 or autocross forum with your goals.

This is the heart of the problem. It would not be that hard to provide the common parts numbers across GM vehicles by RPO and/or VIN. GM (and I think most manufactures) do not give a wit about the cars they sell beyond the warranty period.
Tying part numbers to RPO codes is problematic in itself as changes to designs, manufacturer changes and the like can and often do occur in any given year. The VIN helps to identify the original equipment on the car as it left the factory and should help in identifying superseded parts. Not just a GM problem. Try buying parts for an older Kubota tractor! We have some great vendors on CF. I just let them help me identify what I need and go from there.

Stupid inconsistent terminology! Which part #?
