The usdm spec gtu (s4) and gtu's (s5) na's had 4.30 rear ends too. The s4 used the clutch type lsd and the s5 used the viscous style lsd. I have wanted an s4 gtu rear end for soooo long.....

No, the only US model to have a 4.3 rear end was the S5 GTUs (not the GTU). It was a viscous LSD.

Some of the brochure pages are temporarily unavailable (I'm working on getting new copies), but the manual '87/'88 GXL & '88 GTU had 4.1 LSDs. I have one in my car. Automatics received 3.9 LSDs. For S5s, nothing had LSDs except TIIs and the GTUs

Thanks rotaryrocket for clearing that up for me. I was always told the 88 gtu had the 4.3 lsd. I almost bought one for my gxl. My car didn't want to run the day I was suppose to pick it up. It sold the next day. Glad I saved my money lol

I had an 88 GTU and it definitely did not have a 4.3 . The 88 GTU is basically T2 suspension with GXL driveline (n/a LSD, 4 pot brakes)
