what they are saying is - you do what you like so it will "look" awesome.
right up until the 4wd poos itself and you have to repair/replace the 4wd transfer case.
the skyline attessa needs the same rolling diameter front and rear in order not to shit itself. You use different width/aspect ratio tyres at your own peril
and while I'm not here to tell you what to do - it's your car - i will say:
1. it looks shit
2. the camber you'll run will destroy tyres instantly
3. the wear on CVs, etc will be greater
4. you run the risk of damaging the rim much faster
5. it will be uncomfortable as an enima, so if it's your daily ride, good luck with that
...and probably a whole lot more issues.
But hey, what price to get the bitches (which, contrary to what car modifiers think, it won't help you. F&F has a lot to answer for).
