Does anyone have any dimensions of a Sierra upright with top 'mushroom adapter' in place?
I'm after dimensions such as the distance from top to bottom ball joint centres, offsets, Steering Axis Inclination (KPI) - which I beilieve is approx 13degrees. I'm trying to model my front suspension and need as much detail as possible. I will publish all my findings, such as scrub radius, swing arm length, kinematic roll centres etc.
At present I wouldn't mind if the measurements were made with string. I think the sierra unit is a strong possible option but not 100% decided.
All help very appreciated

perhaps you could go and measure one nearby? come on lads anyone near dorchester with a pair of uprights?

i doubt sierra uprights are too expensive from your local scrappy?

I will be selling my uprights soon in favour of some alloy ones if you intrested
