First Generation Firebird-L Mailing List ......................................................................... You want the pinion to have a downward angle of up to 6 degrees.
What it does is try to mare the drive shaft and pinion straighten out lifting the front end, this transfers weight to the rear tires. An upward pinion angle would have the opposite effect, pulling the front end down and 'wrapping' the housing and unloading the tires causing spin. I am sure there are fancy digital protractors out there but the cheap sears model will work fine. Don’t get all hung up on half's and tenths...you are not build in a Nextel cup car. Or are you ?!!! -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Stu Langer Sent: Monday, February 02, 2009 8:21 AM To: First Generation Firebird-L Subject: Re: [FGF] Pinion Angle First Generation Firebird-L Mailing List ......................................................................... So, the rear end angle should be +2.4? That would mean a 3.2* shim. Maybe you could get the 4* shims and file or grind them down. They're made of aluminum, it should be pretty easy. Stu P.S. What kind of tool are you using that measures in tenths of a degree? ----- Original Message ----- From: "S Sterchi" <[email protected]> To: <[email protected]> Sent: Sunday, February 01, 2009 6:13 PM Subject: [FGF] Pinion Angle > First Generation Firebird-L Mailing List > ......................................................................... > > I'm looking at getting axle shims to dial my pinion angle in.
