My '99 WS6 1LE about to go under the knife

**bma2** · 08-03-2010, 11:59 AM

I've decided to change the rear on my 1LE. I need to get confirmation from this forum that the stock rear is 3.42. With recommendations of how much higher to go and why. The original window paper says it came "Tenser" limited slip rear, but I'm not impressed that that did much!! Is a version of Posi-traction that is better available? Any recs on this?

Thanks, bma2

Check the RPO codes on the end of your driver door. There will be a "GU6" if it has 3.42's. If not, you can compare what you find to the list here: RPO Codes
