@ Niki:
Please tell me what you know about "superpro antilift bushes".
I decided in superpro bushes for several reasons.
First of all the material is better than powerflex and you get a 3 years guarantee(or 32k miles)
The superpro antilift is an eccentic bush that goes in the existing rear aluminium mount of the lower arm.
So you dont have to change the all mount(as WALK) but only the inside bush.
Depents on the angle you fit the inner bush,
you can adjust the caster degree and the antilift effect.
The more ''forward'' the hole is fitted,the more caster you get.The more ''downwards'',the more antilift effect you get.
The price is lower than the WALK and you can get more than 9 deg.caster when with WALK you get a standard 8,5deg.
Finally the bush is a 2 pieces kit (inner,out),so there is abrasion between the 2 pieces of bush when the arm is working.
Here is a link with the eccentric antilift bushes.
