jezzza Posted July 30, 2014 Share Posted July 30, 2014 Hi from Australia! So im trying to decide on wheel sizes for my 260z, and as the tags suggest, my aim is the car to end up having aggressive stance and being slammed I want to ask people for suggestions which they have actually tried themselves! AS there is so many wheel choices from stock wheels to 16x10.5 -32!! Its hard to pick which ones will fit 'perfect' without the annoyance of rubbing etc. (but feature articles dont suggest any of this) I need to run 16" or bigger wheels (but I prefer 16".. im running R32 GTR brakes upfront, and SMM rear brake kit. I will be running coilovers with camber plates and probably running max negative camber (-3/-4*) I was thinking of running F:16x10 +0 (225 wide tyre) R: 16x10 -25 (225 wide tyre) Tyres will obviously be stretched, and yes I will be running ZG style flares Has anyone had any experience with similar sizes to this? Any scraping, rubbing when turning or going over bumps? Would it clear coilovers easily? Do I need to run any spacers? Any idea if these will clear R32 GTR front brakes? Thanks all Quote Link to comment Share on other sites More sharing options...
310z Posted July 30, 2014 Share Posted July 30, 2014 I would say your calculations are about right. Wheel design will be the deciding factor in clearance to the brake caliper. 245 tires should have no problem fitting and possible wider. I run 225-50-16 on 16x8 -0 off set BBS wheels stock suspension. Only problem was the front stock lower valence when turning, so in installed a front air dam. Nothing touches the tires.

Boog Posted July 31, 2014 Share Posted July 31, 2014 I'm running 15x9 0 offset, 225/50's with coilovers. I had to trim the stock spring perches a bit in the front, but they fit fine besides that. Also, I second the need for a new air dam, mine rubbed, got a new one, tada. Quote Link to comment Share on other sites More sharing options...
jezzza Posted August 1, 2014 Author Share Posted August 1, 2014 Thanks guys... Just to make it clear, I will definately be running bolt on flares and coilovers. If you are running coilovers, why did you have to cut the stock spring perch? That means 10 wide 0 offset will hit the coikover strut?

thedarkie Posted August 1, 2014 Share Posted August 1, 2014 (edited) If you're chopping the fenders and running flares, why would you only go with a 225 tire? You can fit that under stock fenders. Edited August 1, 2014 by thedarkie Quote Link to comment Share on other sites More sharing options...
rejracer Posted August 1, 2014 Share Posted August 1, 2014 (edited) To fit coilovers you need to cut off the old perches and weld on new at the right height. A 10" wide 0 offset will have about 25 to 30mm interference with 2.5" coil overs. If you were to put a 8" spring and be able to clear the tire, you still might be hitting the strut tube, Not to mention the reduced turning radius. If you want to start engineering, I suggest getting a tape measure and get under the car. With that said I have experience with a 225-50-16 on a + 10 offset wheel. Benefits of the 225-50-16 on an 8" wide +10 offset wheel: The biggest tire you can run under stock fenders. (but still need coil overs) Can run the same size front and rear with the same offset. It's the cheapest tire size available in the range of use for a Z car. It has the most selection of tires on the market today. (at least here in the US) It's the same diameter as the stock tires (24.9 to 25"), so the speedo is correctly calibrated. No spacers required (front or rear) Good sidewall height for use on rough roads In other words the 225-50-15 is a great tire for street use. If you are racing, there may be better choices. If you want wider and are flaring go for it, but for traction, stability and safety, fit the right size tire to the correct rim. 225's should be mounted on a 6 to 8" rim per most manufacturers. Mismatched rim/tire combo's don't support the sidewalls correctly, and traction goes DOWN. It boggles my mind why you spend so much money on mismatched tires/wheels, don't do it!. To fit a 10" rim, your wheel will need a lot of back spacking or spacers, something in the range of +35 to clear 2.5" coil overs, depending on your exact coil over kit and rim selected. Not to mention a minimum of 255 width tire. Edited August 1, 2014 by rejracer Quote Link to comment Share on other sites More sharing options...
jezzza Posted August 3, 2014 Author Share Posted August 3, 2014 I wont be cutting fenders at all.. I may roll them I need the tyre to tuck under the metal stock gaurd, hence why I need to run stretch tyres on a wider rim Im thinking now 16x8 fronts with maybe -25 offset and 16x10 -25 rears Quote Link to comment Share on other sites More sharing options...
rejracer Posted August 3, 2014 Share Posted August 3, 2014 (edited) With a -25 offset the wheel will rub the stock fenders, I don't know for sure if rolling will fix that. Going from +10 to -25 is over an inch to the outside of the vehicle so really I doubt it. How did you come up with -25 offset wheels would fit? a +25 16x8 will rub the spring perch, unless the bottom of the spring perch is above the tire. Your inner tire will also rub on the inner fender lip, the one on the lower edge. To give you a better idea: +4 can be run in the rear, but requires spacers in the front, or you will rub coilovers. Anything more than + 10 and you will be rubbing front and rear on the coilovers. With +10 if you carry a 200lb load in the back compartment and have a 200 lb passenger you will rub the rear fenders every so often going over bumps. 16x8+10 with a 225-50 tire is just about maxed out on a stock fendered car. With that said, how much clearance will rolling give you? I've never rolled fenders before. Thanks.

jezzza Posted August 5, 2014 Author Share Posted August 5, 2014 Looks like 16x10 +0 wont fit fronts Ill have to run negative offset 8" wide then! Ive gotten my sizes from various different cars running insanely wide and negative offset wheels http://www.stancenation.com/2012/04/07/classic-beauty/ (16x10.5 -32 all round) Also a popular size with the RB rotas are F: 16x9 -13, R:16x9.5 -19 (with flares) I basically chose a size inbetween the two above sizes Quote Link to comment Share on other sites More sharing options...
osirus9 Posted August 6, 2014 Share Posted August 6, 2014 Why in the world are you trying to install flares without cutting the fenders? Your wheels will never be able to get close to them due to the stock fender being in the way. You'll never get that stanced look you're after. Just follow this guide or have them installed, it's not that hard to cut the fenders. http://forums.hybridz.org/topic/47525-how-to-mount-them-there-zg-flares/ Quote Link to comment Share on other sites More sharing options...
