Depends on what you want to do in the long run bud, if it's going to be a street car leafs will be good enough, ppl here have track cars still with leaf setup, im building a 1200 coupe for the track and will still run leafs, if your going to have BIG power and so on then I'd may e spend the extra and do a coilover setup in rear! I've looked around and some ppl leave one leaf in to locate diff and go coilover shocks which would be a cheaper way rather than 4 link!
But really up to what u want at the end of the day

totally agree.

There are successful race 1200s with leaf springs. But then 4-link can be made to work well too (although it's easy to make a 4-link that doesn't work well). There are also successful big power cars with leafs.

It's like the old saw that double-A-arm suspension are superior to McPherson strut. Lo and behold it's usually true. But then Porsche makes strut suspensions that work just as well.

With the way leafs can be played with these days to can make a big difference depending on the way you want thing setup! Shocks also make a big difference on the rear to so a good quality shock could make a big difference! Some people use tarago shocks and some ppl use a 4x4 shock, I've used heavy duty pedders shocks and have had no problems! There are a set of kyb shocks fs here they are good!
I'm yet to try Retrorallys setup in my coupe yet which is Bilsteins shocks and spherical bearings in leafs!

something like this... dont need massive HP to warrant it do you?

Not if u want to do it and want to spend the $$

Only be spending money on the materials... got all the welding gear at work and I'm a decent welder lol
but its only a thought, a way of having full height adjusting rear :)
