This is the happy medium between the ultra stiff nylon replacements available elsewhere and standard bushes. They have been chosen in a .75 shore rating to allow enough play to stop the rear end being twitchy but still stiffen it up nicely. A long over due polo mod, great for sorting that back end out.
They will be coming in at £60 delivered for a pair, are a direct replacement to the standard bush and comes with the metal insert.
