    yep.. support the car under the steel subframe by the shock absorber....

    then undo and remove the long cross bolt before letting the jack down gently...

    I jacked the car up under the jack point and undid the bolt. No need for a trolley jack m8. There is no pressure on it and you will have to push down hard on the arm to get the rubber seating of the spring to free it The new spring is shorter so again should not need jacking up to refit the bolt. I jacked the arm up for support more than to compress the spring.

    Don't take my word for it though, Mark has done far more of these so i'd follow his advice

    you flatterer..:..

    i use the jack as an assist only.. but it's necessary in 'world record' attampts.... helps bring the arm up gradually to help it realign with the void bush and to get the holes in line..don't be afraid to drive the bolt through to realign it before tightening it up again

    Default lower it

    Did mine last wk put spax 40mm drop all round did the whole car in 2 hours
    Jack the back up on the bottom leg use an axel stand in the middle of the car. Use a trolly jack under the lower bar pump it up so it just takes the strain undo the lower arm bolt use a punch to push it out then lower the jack the arm should drop down.Remove the jack a use a pry bar to push the bar down towards the floor.Pull the top end of the spring off first the rubber will prob come off with it.Pull the spring towards the rear of the car and it shoul come free.

    re fit: put a small amount of copper ease on both rubbers and replace them,With the pry bar push down and put the bottom of the spring on first,Then the top,

    Put your trolly jack under the arm and appy copper ease to the outer edge of the arm this will help with recetin the arm, Jack the arm up slowly
    till the hole's match put your bolt threw tighten and walla done should take about 20 min (check mine out ) laffin, Used spax 40mm drop
