I used 'Siverlines' on my 4dr mk3 and they ticked all the right boxes but like all coilovers had there do's donts and drawbacks.
Theyr made in the 'Jamex' factory appparntley, and are basically the same gear.
In my experience, they were the whole same deal as my weitec hicon-gt's, that I used on my passat B4 estate.
It seems to me theyr all much of a muchness.
A few years back! But at gwentVW the silverlines were 250 delivered including vat, and the wietecs were about 650-odd. i was very happy with both.
I thought both cars handeled more or less the same and hope you hav as much fun as I did.
Get stuck in lad, and get it slammed
