Default ELBJ Alignment Numbers

So I just installed all 'new-to-me' control arms with ELBJ and steering rack spacers on my 91. 3.75" front pinch weld height. 14kg/mm front springs. 225's on 15x9 wheels and 205sm7's on 15x8

The problem I am having now is that I cannot reach my caster target of 4.5* on either side of the vehicle. Left is minimized at 5.7* and right is minimized at 6.5*. Currently at -3.6* of camber on both sized.

My question is, What sort of alignment numbers are people seeing with the ELBJ? The car isnt difficult to drive with this much caster but I need to get them closer to stop the car from pulling and really want to know if I can expect the numbers to behave more naturally if I dump more camber into the front.

On my NA with an NB subframe, NB control arms, and NB spindles we couldn't get less than 7* caster running ELBJ.

4" pinchweld
3.2* camber

Sounds like you are in the right ballpark with an NA front end.

Drop the camber down to 3* and see what the caster does?

Cool. Ill get it back up on the rack and get it all evened out soon.

With less camber, the caster went even higher. It was sitting at 7* caster with -3.4* camber and -3.6* allowed for the 6.5* caster

Yeah I had the same issue. Less camber made the minimum caster I could get increase. 7* caster isn't that bad to drive though, and I'm running 15x9/225 NT01 with an NB manual rack.

Are you guys sure you're going the right way with the eccentric bolts? You want to move the outer ball joint towards the rear of the car. So trailing eccentric should be all the way in and front eccentric should be all the way out. That is the minimum caster you can get ignoring camber of course.

If you are running less than 4.5" front pinch weld with ELBJs, you are sucking at life, HTH

If by "isn't that bad" you mean "virtually undriveable for more than 10min at a time", then sure
