5Zigen FN01R-C Wheel Fitting help?

[jazz4890]

I am thinking about getting The 5Zigen FN01R-C wheels they are 17x9 all around with a 20 offset and I have gab shocks and struts for a suspention lowered about an inch maybe an inch and a half and I will be running 235/45/17 all around to does anyone know if there will be any fitment problems? any help would be greatly appreciated

Why are you Stretching 235's onto 9 inch wheels? That doesn't make any sense. Why not get an 8 inch wheel and stick with your 235's?

They well fit and you won't have to ask these questions.

I am using 17X9 on the race car and fitting a 275 with other modifications, 235 is superstretched, it seems to be a waste of money to me especially on a street car.

[jazz4890]

Really? I was thinking of running 235 because when I was reading a lot of the threads about the falken hanabis people were saying get a 17x9 and put 235 all around its a good fit and so I thought that would be a good fit for these wheels since they are the exact same offset as the hanabis

[MagikDragon]

If you are planning on Drifting then a stretched tire is good. But for daily driving than a tire that is square with the wheel is good. so an 8 inch wheel sits really square with 225-245 depending on tire manufacturer. these will also fit within the stock wheels well, with a fender roll all around.

an 8 inch wheel with a 30mm offset will fit all around with no problems. Just some food for thought.

[jazz4890]

ok so what if I got them 17x8 with a 225 I will need a fender roll?

[MagikDragon]

With what offset? You might be ok. It really was close when i got mine, but I had 245's and a 30mm offset. I think you'll be good, the issue I had was with that lip that sticks inward toward the tire, once that was rolled in I had no issues.

[jazz4890]

The offset is 20 I read that a 235/45/17 with a rim that is 17x9 with a 20 offset is a great fit that will be flush.

[jazz4890]

The offset is 20 I read that a 235/45/17 with a rim that is 17x9 with a 20 offset is a great fit that will be flush. Is that not true?

[MagikDragon]

I think you need to do some more research yourself, as I don't have all the answers.

zerothread/265282that is a good place to start, I can possibly dig up pics of my setup so you can check it out.

[gumby74]

A 235/45 is too tall of a tire.You will want a 235/40 on a 17" wheel. It will be slightly stretched, and the overall diameter of the tire will be a hair under 24.5". The problem at this point will be the fender gap. For a more appropriate fit you will need more lowering than springs and shox can give. Should you go with a 17x8, than look into a 225/45 tire that is just at 25" in diameter, and will fit pretty close to square on the wheel.

[jazz4890]

ok I am looking for the sidewall to be thin but I dont want the tire to be stretched so what size tire will be like that? and I will be getting the 5zigen 17x8.

[carmo]

Quick math 25.4mm make 1 inch...so a 9 inch rim =228.6mm wide. I just got some LMGT4 wheels for the 350z at 8.5 all the way around. 8.5 inches make 215.9mm. the rim, outside to outside is 9.5 so my 215/ 35 18 tire turned out to be super stretched. Your rim may be 10in. wide outer to outer so thats 254mm. this may not be the case for your rims but if it is and you dont wanna stretch you may need at least 245s

[carmo]

for a 17x8 the width would be 203.2mm. So for the strait up look a 205 might be what your looking for. On my accord I have 235/40 on a 7.5 wide wheel. the look is real. No tuner show car look at all. And the increase in traction is noticable. Just remember the aspect ratio is crucial. so on my accord tire thats 40% of 235mms. 235mm=9.25in. and 40% of that is 3.7in. so the side wall is 3.7in. BUT thats not 3.7 from the outer diameter of the rim, thats 3.7 from where the bead of the tire seats. Take it from me, you never know unless you get good pics of other set ups or you buy a 215/35 18 for an LMGT4 and find out the hard way. math is your friend but pictures are worth a thousand words....514....

[jazz4890]

so after reading everything I am thinking I will go with the 5Zigen FN01RC's they will be 17x8 with a 35mm offset but I am still very confused about the tire and how well it will fit on the wheel should I get a 225/45/17 or a 235/40/17? and I think the 205 tire will be to small or am I wrong I dont know that much about tires so any other info would be great and I dont have a good understanding of offsets either sorry for the newbish questions

[jazz4890]

bump.

[gumby74]

On a 17x8, a 225/45 will fit very nice and square. Total diameter is just at 25" which is the biggest I personally go in regards to rolling diameter.A 215/45 checks in at about 1/2" shorter and will have a very mild stretch to it. The 235/40 on the other hand will be bulged out a little bit.Now you have 2 more things to consider. Different tires have different shoulders to them. If that makes any sense. Some tires have a very defined shoulder and generally look very square to begin with, while others have a somewhat undefined shoulder and are naturally rounded out. It's not a big deal, but sometimes that little bit of squareness/roundness is essential for clearance. Considering your chosen wheel sizes though, I would go with the 225/45, and pick up some 10mm spacers or so. On an 8" wide wheel, you can go down to a mid to high teens in offset with no rubbing or clearance issues. Should you, of course, decide you want a bit more flushness than the +35 offset provides.

[jazz4890]

thanks for the help man why would I need a 10mm spacer? would I need it to make the wheel stick out a little further to make it look more flush?

[unlearning]

Aesthetically, yes you would need the spacer to flush out the wheels with a +35 offset. Theoretically and more importantly, you need at least +25 offset to clear suspension parts otherwise you are going to be having rubbing issues, tires rubbing coils/shocks.

FN01R-Cs can be bought in 17x8 +25 or 17x9 +20 or 17x9 +15. Those are going to be a better bet and save you money in the end.

Look here and compare zerothread/265282

[jazz4890]

so if I want it to clear the suspention then I will need it to be +25 offset? so the +35 offset wont clear the suspention?

[jazz4890]

also another question if I go with a 17x9 +20 and a 245/40/17 or 245/45/17 will the wheels and tires fit good without spacers? my car is lowered with springs and strut like an inch or an inch and a half I would do a fender roll to make it more flush but I just want to know whats a good size wheel and tire for my s13 that will look flush without spacers.

A 17x9 +20 will have the front wheels sticking out just a wee bit from the fender. That's where you want to be. A 245/40 up front may result in rubbing issues, however your problem at this point will be the fender gap. The same tire fits beautifully out back though.The 245/45 tire will be too big from a diameter standpoint, and will probably bind on the strut hat's up front.For reference, I am currently running 17x9 +14 with 235/40 Sumitomo tires up front, 17x9 +27 with 245/40 Sumitomo's out back. (I have new 235/40's for the rear, but the 245's still have some meat on them, so I gotta stretch my dollars a bit) I have no clearance issues at all, at about 3" of drop front and rear. All that was neccessary was a lip roll in the rear fenders. If I can find the friggin' cable for my camera I will get you a couple of shots.

[jazz4890]

So should I use a smaller tire up front? Like a 235/40/17? Or should I get a spacer? And with the setup I want to run do I need to roll my fenders? My car isn't lowered to much I can take pics to show how low it is if you could tell how well it would fit that way

[gumby74]

I was running lowering springs and shocks for a while there, so I have a pretty good idea where you are at.The only issue I had with these set-up's was the front needed to come down a bit. At this stage, I was running 17x8 +14 wheels with 225/45 tires up front, and 17x9 +27 wheels with 245/40 tires. With the lowering springs, this combo looked aesthetically correct to me. The front tires were just a hair bigger in diameter than the rears, so the fender gaps where similar. I had no reason to run crazy camber, so tire wear and rotation were not that big a deal.

[jazz4890]

Really ok so the wheels I want to use are 17x9 with a 20 offset if I got them in a 17x8 the offset would be 35 so should I run a 17x8 in the front with 225/45/17 and then run 17x9 with 245/45/17? Would that be a good fit?

[gumby74]

Go down to a 245/40 for the rears. You may need a lower offset on the front though. You will be pretty close to the strut hats with the +35 and the 225/45 tire.For the sake of clearance, you want to be at least +25 or lower offset for the fronts. Longer wheel studs can be had for under $60 if you go with Nismo or less if you buy the Circuit Sports or Ichiba extended studs.If the 17x8 is offered in a lower offset go that route, then if needed you can run a much smaller spacer up front.

[jazz4890]

so with the 17x9 +20 offset in the front would that be a good fit in the front? with a 225 tire?

[jazz4890]

ok I have decided to go with a 17x8 all around and if the rear is sunken into the fenders to much I will probably just get spacers thank you for all of your help I appreciated it you guys helped me a lot with my decision on wheels and tires I hope this helps someone else someday.

[ThuG LyFe]

i'm not sure about S13's body but i just got the 17x9+20 installed on my s14. perfect fit. front is flush the rears will be flush with some RUCAs. i love the fitment of them don't get 17x8+35 i was debating on getting that too but i'm glad i didn't. then again S13 might be different...

SPLparts.com had some pics on S13's and they looked pretty good.

[jazz4890]

well I know they fit good on a s14 but there lugs and body style are way different so I am sure the wheels fit differently to but if you know someone with an s13 with some 5zigens that are 17x9 let me know how they fit on his/her car.
