The workshop manual states 9 degrees plus or minus one. All the racers recommend 10 degrees. With only 4 degrees you really have to steer the car out of corners.Just curious. Ten degrees of positive caster seems like a lot, in Citroen 2CV territory. elaborations are of interest.
Wow! I went back and checked the chart and am astonished that it calls for nine degrees. Every other model is in the 3-4 range.The workshop manual states 9 degrees plus or minus one. All the racers recommend 10 degrees. With only 4 degrees you really have to steer the car out of corners.
Yeah an interesting difference.Wow! I went back and checked the chart and am astonished that it calls for nine degrees. Every other model is in the 3-4 range.
That would be my guess. I've had a number of BMW' and they are known for having a good bit of caster for "speed feel." However, that's about 5 degrees.Yeah an interesting difference.
From what I have read the notable caster is due to how light the front end is.
I have checked out the Fiatnutz ones. They put the control arm out a bit but don't alter the height. The first units are out of stock. I like the look of the alloy units Hegen Speed has on his car he manufactured from alloy. I think I'm going to fabricate my own out of steel. Raise the height about 30mm and have them out 10mm each side over standard. Then I'll adjust the lower wishbone rose joint out by the same amount so I will be starting with a similar alignment before I fiddle about.
Photo is Hegen's front end.
Sorry, I meant to have an arrangement which used Johns nuts in combination with your first photo. I wasn’t clear.John's method just moves the trunnions out. Does not address adjusting the height bit. The first photo is my set up and the trunnions look like they need to be higher.
The second photo is pretty much what I had in mind.
