Default 1990 ZR-1 'Active Suspension' Z5Z VIN & RPO

I didn't find a particularly obvious place for this post so I thought I'd just create a 'NEW' Thread.

I fabricated a VIN list of the '90 Z5Z 'Active Suspension' cars and I've compiled RPO lists for all 17. My VIN 'list' I believe will pass all tests. A GM VIS on a few actually show the completion of the seat belt recalls. Pretty interesting cars. A typical '90 would have an ECM code of AUAH. These cars I believe have ACFF ECM.

If this needs to be moved to any particular place LMK. I'll hold on the VIN list, RPO etc until someone mentions where they'd like it. It doesn't pass the requirements for 'PROTOTYPE'.

I've returned as a 'Paid Member' so I'll post the VIN list here and fabricate best I can a SPID label.

------------------------------------------------------------------------------

I've always offered all C4 FSM in .pdf and many have mine as well as their paper. I also have and include with a FSM purchase from me a GM SPO Parts Catalog.

If the FSM and GM SPO Parts Catalog interest you send me a PM or email. I can deliver the FSM anywhere generally the same day paid. I also have the LT5 Supplement.



I've considered maybe offering a VIN specific 'RARITY' for all C4 if the FSM package is purchased.

I let my 'RARITY' subscription expire because I had some issues with GM VIN newer than 2012. Through 2011 it seems to still be intact and functional but newer nothing more than a complete SPID list.

If there were interest in years through 2011 for 'RARITY' I'd likely renew once I sorted it.

This is I believe a correct VIN list for the Active Suspension Builds. I've had GM VIS run on a few but have confirmed option content on all. Some of these actually seem to have had the Seat Belt Recall 'closed' on them.

1G1YZ23J4L5700001

1G1YZ23J6L5700002

1G1YZ23J8L5700003

1G1YZ23JXL5700004

1G1YZ23J1L5700005

1G1YZ23J3L5700006

1G1YZ23J5L5700007

1G1YZ23J7L5700008

1G1YZ23J9L5700009

1G1YZ23J5L5700010

1G1YZ23J7L5700011

1G1YZ23J9L5700012

1G1YZ23J0L5700013

1G1YZ23J2L5700014

1G1YZ23J4L5700015

1G1YZ23J6L5700016

1G1YZ23J8L5700017

The SPID for these cars would likely have been:

AC1 AC3 AJ3 AQ9 BGR CC3 C68 D74 DL8 D4L D9B E5Z E9Z
FE0 GH0 G87 J55 K09 LT5 ML9 MN6 NA5 NK4 QA2 T93 UJ6
UX0 U1F U52 V73 WD1 XAU YBE YE8 Z5Z ZR1 Z51 19I 193
199 24S 41U

BC/CC WA- U8555 193

Default Re: 1990 ZR-1 'Active Suspension' Z5Z VIN & RPO

This image is a complete RPO list that's based on 1990 Production compared to 16,016 that had potential year & model matches.

The RPO that match the 17 only Z5Z cars are other than the Z5Z (Active Suspension) are D4L (No Description), FE0 (No Description), GH0 (3.54 Rear Axle). The FE0 we can 'speculate' but likely would have become the FR & RR Active Susp RPO, D4L - I believe is the speedo driven to match the 3.54 rear axle ratio. These appear to be the only GH0/3.54 builds in 1990. There were random GH0/3.54 in '91 & '92 I believe but no ZR1 with.

These cars also shared WD1 (Pilot Vehicle), YE8 (Engineering Test Vehicle) which in '90 there were WD1 - 61, YE8 - 62.

They were all 41U (Black) w/C68, CC3 (24S) 193 (Black Leather)

They all also had D74 mirror option that in '90 might have only been seen in 45 builds.

Another 'oddity' with this project is LT5 (3,051) which matches K09 (120A Alternator).

ZR1 (3049) which is a number we see often.
