Koni str.t kit

I've had my mk2 FR+ for about a year now and despite trying to get rid of it before xmas I've decided to keep it. On the last mot one of the shocks was weeping so instead of just buying oem I've decided to upgrade and have a little fun as well as try and sort out the bone shaking ride. I've read a few good reviews on the suspension kit and have a few questions.
Will I need to fit new drop links or any other parts due to the drop in ride height?
Is it more comfortable than stock?
And will i need a full 4 wheel alignment?

Many thanks, mogsy

Ok Damian thanks,

What about the strut size, some companies are selling these shocks at two different sizes 50 and 55mm will that make a huge amount of difference?

Ok, are they the 55mm you sell on your site?
Would there be any other products you'd recommend at a similar price to this?

Which one of those 3 would you suggest?

Kinda want to keep some comfort there too, I understand it's not going to be perfect but it is still my daily
