wheel options

[02cab]

Hi Guys

1st post so be gentle,been a reader on here for a while so thought i better sign up,some fantasic cars

im building a 1302 cab into a gl and looking at wheel options,the cab is standard discs and drums not been lowered etc (at the moment)

i want to keep the stock wings

1st choice are 7.5 x 17 et52 t twist from machine 7 and buy the discs and drums for the 130 fitment
would spacers also be needed?and would these alloys fit on the standard wings

or

i notice that you can pick up cheap 16" boxter wheels on ebay
ive seen a set of 6 x 16 fronts et50 and 7 x 16 rear et40
what would be required to fit these spacer wise or can they bolt on once the bolt pattern has been changed?

forgot to add id get slim struts and springs - any ideas on the best ones to get?
thanks
