If you were moving from the standard 16" wheels that come with a BoraAs I understand it, for your car to look the
same as it is now, every wheel size you go up, the suspension needs to
come down 15mm, i.e 16"-17" etc.
It was only if you went for the santa monicas, they gave you 15mm
lower springs, to compensate from going up from 16" alloys I think!
So how do you explain this then, when the larger the alloy goes, usually the smaller the tyre profile becomes, thus keeping the wheel/tyre radius combination as near to standard as possible in order to help reduce speedo inefficiencies??

If you want to understand the wheel tyre ratio differences, look here http://www.rochfordtyres.co.uk/tyrecalc.asp and try a few combinations - it will give you the rolling radius and the speed difference between them.As I understand it, standard golfs are on 16" alloys GTi/V5/V6 yes - TDI/S/SE/SDI - no
with santa monicas, 17"s, they give you 15mm lowering springs That was an option pack, you could've had Santas without the sports suspension.
Annis have 18"s, and they are 30mm lower.That's because the Anniversary suspension was further developed for better handling, not looks.
a 18" wheel is 25mm larger than a 17" rim, tyre profile reduces from a 45mm tyre to a 40mm profile for a 18" wheel, which either side adds up to 10mm, so theres a 15mm difference between the 2, so thats why I assume the drop, as if thats what vw do with theior lowering aswell, it matches what I said. I think so anyway!!!!!!!!
If what you are sayign is the case, why when you put bigger alloys on, your car ends up looking like its on stilts? The gap in the wheelarch is the same, as the rolling radius of the wheel and tyre is the same (otherwise you'd have massive problems with acceleration and speedo readings) the 'look' of larger wheels and lower profile tyres simply changes the appearance of the gap.
thats the only reason I could make out, unless anyone else can help out?
