VIN Range for Early vs Late Rear Suspension
After doing an exhaustive search, I'm throwing in the towel and shamelessly requesting your assistance.
What 964 [Coupe] VIN range defines the pre-91 rear suspension vs the 91-on rear suspension? If VIN is not possible, is there a general month/day cut-off?
I have money in hand ready to upgrade my suspension and want to me 100% sure what I'm doing. I have a '91 model, but it's got a 6 Nov '90 build date.

The build date change over was 1 November 1990, so you're right on the line. You should have the new style mounts, but you'll need to verify by checking at least the VIN and possibly inspecting the mounts visually or checking the part numbers. This thread has all the information.

Wow, good link!
My VIN ends in 410892, so I'm about 370 cars into the new (91-on) side.
Thanks!
You can either check the part number on the bottom of the rear-side of your rear shocks, if it says 964-333-051-05 than you have the old style and if it says 964-333-057-00 than you have the new style. You can also check by VIN number, the last 5 digits of your VIN should be greater than 01467 for you to have the new style. (i.e WPOAB2964MS401467 should be the last VIN # with the older style shocks on a ROW model and WPOAB2964MS410518 on a USA/CAN version) These numbers are for USA based C4 coupes only, it is different for ROW, C2, Targa, Cabrio, etc. The other way to tell is to check the options label in the front trunk for M030, the sports suspension option was not available for older style cars.

it seems TIPs and manuals vary on start date also. i wouldnt go by number when you are that close. Go by what it looks like. The old has a deep set in top plate and the new style is flatter. By the way mine is 9/90 and the new style.

Yeah, the dates can't be totally trusted. Gotta look at them but it's easy. Lots of links.
