Hi Robo,
I've been thinking about the design of my upper front wishbones and think I'm going down the "Rose Joint/Heim" route istead of polybushes.
I believe on Algas thread you said the MX5 caster is 5 degrees. I was thinking about moving the top ball joint adjuster rearward to achieve 6 degrees with the Rose Joints at 90 degrees to the pivot bolt.
I'm going to use misalignment washers and machine some spacers for the suspension brackets to take up any slack.
This will give me the option to dial in a caster angle to suit the geometry for the front of the car.
I plan to bend the top tubes and weld on threaded inserts onto the ends of the tube which will give a cleaner look......
The outer camber adjuster will be adjustable whilst on the car without removing the ball joint but it will not be a bought in item as I'm having some parts machined up.
Like I said not finalized yet so any input from anybody will be appreciated.
