    The ride can be harsh. Nothing wrong with the product if that suits you. In my experience they need periodic
    lubrication. Not for me now although Ive had them on other cars like yourself. You can get them For Ferraris
    plus there are some other non standard options too if you look around.

    Just seen Davo response......looks like we are all assessing this job soon as bushes are starting to crack like yours.
    Powder coating and blasting. The cracking is not so bad although that is the sign things are getting tired in my eyes.
    I would be more concerned about the other photo and the gap between the arm and bush. As I said it can be hard
    to spot on the car. Only stripping revealed the gap.

    You may want to consider coating the arms in acf-50 when you have fitted them.

    It's an aircraft rust protection spray grease, I've seen it recommended by a few others - no real experience of it myself.

    I just tried to jack the car up, but can't feel any movement in the suspension. May be better if I get it on a 4 point lift rather than just a trolley jack!

    As I said it could be anything. Maybe nothing to do with the suspension.

    Here is an unusual shot. View of the channel where the steering rack and roll bar are located. As you can see there are a few things to negotiate when removing and refitting.

    Valid point. I've been chasing what i thought was a front suspension knock for a couple of years. Turned out that it was the bonnet internals knocking when traversing bumps

    A friends suspension company do the internals for me. New oil, gas and check all is well in there. I do the rest.

    Rack looks a tad mucky. I don't think its any sort of leak as such. just over the years its sweated out of the covers and been covered with dust etc. Not easy to clean properly when fitted. There is semi fluid grease in the rack not oil, and
    that generally dose not leak easily. The chrome centre tube of the rack is fairly corroded so will need refinishing as
    will the track rods. There were no faults with the mechanical side of the rack just cosmetic tidying to be done.

    Covers were coming off for re plating so here are some shots of whats in there. Nothing unusual.

    First cover removed reveals the preload spring and plunger for the rack. You can see it in the hole with the plunger
    removed. Also there are three metal shims which will be factory set. These are different thicknesses.
    Make sure they go back in.



    The second cover removed reveals the pinion bearing and shim pack. Again factory set and need to go back in.
    The bearing was well lubricated. Ive wiped it clean so you can see it. Shim pack in place.
