    lol... 225 tyres?

    No they won't fit and a 225 tyre has no right being mounted on a 11" wide wheel.

    I spent 5 mins zooming in and sussing it out, they are 255 tyres.

    Depends on your suspension and how you want to modify the body of the car.

    Without any modifications to the rear guards and running just a bit of camber with proper size tyres?

    Front:
    8" +30 with 235 tyres
    9" + 30 with 235 tyres

    Rear
    9" +30 with 255 tyres
    10" +45 with 275 tyres

    With a roll and some camber you could clear:

    Front:
    8.5" +25 with 245 tyres
    9" + 30 with 245 tyres

    9.5" +30 with 265 tyres
    10" + 40 with 285 tyres

    If you want to go full stanced and run massive wheels with small tyres, then run 5 degrees of camber and stick a baseball bat between the guard and tyre, drive forward and instant roll. Not suggesting you do it but it is a real method to create more clearance. :rolleyes:

    too low offset, you'll need run big negative camber and tiny tires to clear those

    They have a rim that will fit take about 5 weeks to get here but.

    If they say they fit and they don't I'll return them. I'm happy to wait that's no problem. And in the meantime I'll keep and eye on Gumtree and if something comes up I'll grab them instead . no point getting ya nickers in a knot. If anyone has a set of 18 deep dish rims pm me.

    Q. The million dollar question... Will they fit?

    http://www.willtheyfit.com/ or http://www.fitmywheels.com/

    Forget +20 offset in anything but a 8" wheel use this to determine offset https://www.1010tires.com/Tools/Wheel-Offset-Calculator#


    Forget wheels listed for a 350z look a z32 guards now look at 350z guards

    Q.What's the biggest you can go?

    front 9.5 +38 rear 10 +50 this is the furthest inwards before you hit something with little to no camber, going wider for the rear eg; 10.5 will require a reduction in offset buy 6.35mm eg; 10.5 +44 and so on 11 +38 11.5 +32.
    So going wider and reducing offset pushes the wheel further out the rear guard lip is about 10mm so roll that and get 10mm 1 degree of camber is about 10mm

    Lets say you had to have a 11 rear(this is when you us the 1010tires link), that 11 +38 will stick out by 25mm than the 10 +50 so roll the rear and add 2 degree negative camber or to use that 11 +20mm you would need another 18mm so 4 degrees camber all up, roll and 255 35 18

    Tyres (this is when you use the 2 links I first gave you) All tyre are made different so you go on the manufactures website look up the specs and look for section width use this number instead of 235, 245, 255 ect in the above calculators

    Other wheel factors

    hub bore, no smaller than 66.1mm rarely comes up as most wheel manufactures make them 73.1mm but note it anyway

    Brake clearance or X factor
    If it clears brembos GTR STI EVO 350z it will clear TT brakes, The bigger the lip the wheel has the less X factor ( real lip not cheater lip)

    Stagger

    Most staggers wheel sets induce understeer take that 350z set you posted 9 +25, 10 +20 36mm track front to rear

    A neutral handling set would be 9 +22 , 10 +35

    Don't mean to hijack your thread, thought i would ask here since its related.

    So is this the same with 19inch rims?

    One of the rims i have seen comes in 19x9.5 (offset 20 to 38) & 19x11 (offset 15 to 30) where it can be custom cut to the offset needed. So what would be the best suited offset to fit under the zed guards with no crazy camber or as little camber as possible?

    As mentioned above for the rims i have seen, what would be the most ideal set up to achieve as close to neutral handling?

    Thanks in advance

    rims

    I am running 18x9+15 235x40 18x10+22 265x35 guards flared and probably got room for 285-295 under the rears :zlove:

    I am running an 18x11 +35 with 295/30r18 and -2.5* camber under stock guards.
    Don't have any pics on me, but its flush.

    18x11 +20 could be doable with enough stretch and camber
