rear hub problems for 6n2

[polopowah]

Hello all

right i have a very annoying problem
the rear hubs on my polo 6n2 are bigger than the fronts, therefore i cannot fit any wheels on the rear of my car.
my previous alloys i have on are bigger for he back but i want rid of my 16's so i bought some euro 14's then came the problem fitting the backs!

the new alloys are 14" pcd 4x100 with an inside diameter of 5.5cm, the bolts fit fine and they go on the front no problem

the rear hubs are 7cm across at the widest point so the alloys will not go on problem although the bolts fit fine.

he rear hub has writing on it 2490 65 hct if that helps

could anyone please shed some light on this, are my rear hubs supposed to be bigger on the back? than the front?

im thinking tht i can get some new 4x100 hubs that are 5.5cm wide for the rear.

please help, i have a headache!

cheers
