Hello fellow water pumpers

I am after some direction and advice on upgrading the suspension on my 1977 4 door Mk1. At the moment driving around, reminds of my first waterbed from the 80's with no internal baffles!!
I am after a good road driving car that wont be sending me to the chiropractors every few weeks.
What is a good replacement for the stock bushes? I have read the red ones are bad?? What about the blue ones or yellow ones?
What is a good brand of adjustable coilovers?
Do the sway bars need upgrading?
Im not after a top end spec mega buck setup... nor the cheapest - just a good middle of the road option (I only drive this car on weekends to go to church.....honest lol)

Cheers,

Marty
