Rear ride height affecting camber? Dumbass I meant Caster D’oh!!
So I thought I would try and plot this out - it's more for curiosity than anything else, so a very simplistic representation of how I see it. So the ratio to degree online calculator seems to be correct - 1.7" : 108" = 0.88degrees, but my assumption that it would equate to a 0.88 degree reduction in caster was not right at all, it would appear to be aprox 0.3 degrees.
Thank you Blu that is a very clear summary which from the various threads I had searched on FABO I was begining to understand. A basic assumption that raising the front ride height would dial out the change in caster doesnt account for the much more direct change that altering the front ride height makes to the control arm geometry.
In the real world for me, I guess that maybe it was a good thing that when I ordered my plus 1" springs from ESPO I also ordered some adjustable hangers from Uncle Brians Speedshop! Firstly because the back of the car is sitting waaay too high now which looks a bit dumb and much more importantly because it definitely has changed the handling - it tramps over bumps and is a lot looser than before. So I will drop down 1" on the hangers to dial out most of the lift, hopefully as the springs settle and flatten as well that will improve things further. Thanks all.
