HELP: Wheel modification guides?

[Hjt]

Hey guys/gals,

I drive a bone stock suspension/brakes/springs etc NA6.

I currently have 17 Inch imported wheels that cosmetically look perfect, but are hard sluggish on the road and personally overweight.

I'm looking to get a new set of wheels and tyres;

would 15" 8 wide with +0 offset work with a 3.5 inch lip. (4x100/4x114.3)

or should i get 15" 7 wide with +15 offset 2.25 inch lip.

Or a combination of the both??

Any advice would help, i plan to upgrade brakes/suspension to suit new tyres, and i prefer not to roll the guards.

Cheers

15 x 8 is pretty aggressive. i prefer conservative rather than overcooked, so i'd go with 15 x 7 +15.

would the 8's be better on the back and 7's on the front, or would that create wheel alignment and tyre wear issues?
