It's a complete Cast Alloy crossmember (powder-coated in white, although that was done a few years ago) with Alloy Anti-Roll bar and adjustable arms. I had the brackets remade from Alloy and hard-anodised in Black. Fitting it with a set of adjustable TCA's from someone like MEF will give you masses of potential for front-end adjustment (I might even sell it with my TCA's, depending on what I do).
It is basically what Turbo Technics developed to retro-fit to Mk4's that they converted to bring the suspension up to a good level.
Mine is in exceptionally good condition, all the adjustable parts are excellent and all move. Mostly with this type of set-up, they are grotty and rank.
I will also be selling my Koni's too I would imagine.
