Polyrace Bushes
After carelessly wiping one corner of the suspension off on a tyre wall I decided now was the time to replace the bonded rubber bushes in my front
suspension with Polyrace polyurethane bushes and bought some from the nice Mr Rallydesign.
They come with the center steel sleeve or crush tube about 13mm longer than the bushes - I presume I have to shorten it to suit.
How much pinch or slack should there be?
The polybushes are have an internal measurement of 1" between shoulders and I have made the steel sleeve they fit into 30 thou oversize so the
bush halves will not quite meet in the center. This makes the extermal size of the polybush 1.335" how long should I make the crush tube? 1.32,
1.35" or what?
I don't want too much movement but on the other hand I don't want any stiction. What have you guys done?

Normal practice is to have the parts the same size.
On the Roadster the bracket is 44mm internally, the crush tube is 44mm and the bush in the bush tube on the wishbones is 44mm when assembled.
When done up the wishbone will sit in it's position. So it's best to get the car on it's wheels before tightening these up.
Hope that all makes sense.
