Deciding between my turbo twists or 993 Cup 2s

[buggyboyshane]

hey buddy im fitting a fully chromed set of turbo twists onto a 68 flat screen bug, i have 17x7.5 et 52 for front and 17X9 et 47 for rear.

front is getting dropped spindles and narrowed 2inches

just by offering wheel up at rear i see im going to have to put 20mm spacers possibly on rear, and its gonna stick out....... am i gonna need wider wings? if so by how much......

any help greatly appreciated
