Looking into getting a new set of wheels 18x9.5 +22 offset front and 18x10.5 +15 rear. I have 20mm wider fenders up front and 50mm in rear. I know the rear is fine but alittle concern'd with the front.

 

I would still run at least a +30 offset for 9.5 wheels with 20mm wider fenders.

 

That sounds right.
20mm = ~.75"
+50 (stock FD offset) minus +20 = +30

 

So 8mm is really going to make that big of a deal. I was thinking if i run a slightly more negative camber and a slimer tire (maybe a 245 or 255) it should be okay. Any other thoughts on this?

 

Well, let's put it this way. It's either hitting the fender or it's not. So, yes, 8mm is quite a lot of difference (over 1/4").

If you are going to run skinnier tires, just get skinnier wheels. Personally, I think a widebody is going to look pretty lame with skinny tires/wheels.

What wheels are you considering that have such a narrow offset selection?

 

Well I was hoping I could go with the ADVAN TCII GT-R's but looks like I'll be getting some other wheel

 

So as a point of refference for myself, if I were to run a 10'' wide up front and in the rear, I would be seeking about a 32-35mm offset, to compensate for the additional .5 inch of wheel, correct? Then, for the rears, a 10 inch wide tire, with a 1.5 inch widebody (38.1mm) would necessitate a +12mm offset (using the same rule, +50 minus +38.1 = 11.9 rounded to 12?)? Im just sorta trying to get a better idea for the offset thing, before I give John Purner a ring.

Or do I have it backwards, and should go a little lower offset, being the fact that the wheel is a tad bit wider?

Please post a link, if someone has it, that better explains offsets and how to calculate them


Edit: Found the link that explains offsets, please disregard last question

 

I didn't read thru everyone's post, just hoping i can corroborate what's already possibly stated.

In past I run this setup in 18x9.5 +50 front stock fender and 18x10.0 +50 as well for reference.

50-20fender = +30 offset in 9.5" width
for a 10.5 on an FD with +45 offset and rolled fenders. Because you have FG fenders yours are "like" a rolled fender. I will use this as a baseline.

45-50 = -5 offset.

Depending on the size tire you are running you can play with the rear offset a tad. You have plenty room inside and can run a wider wheel if you so desire, up to 12.5 for sure.

Thanks, Rishie

For wheels like this I would suggest these:


You would have a bigger lip in the rear and the front would be about that depending on whether or not you have a brake upgrade or plan too.

9.5: +30; 20mm wide fender

10.5: -5; 50mm wide fender

I have the same setup of Msport fenders on my FC. Hope to get it back soon. I just got my work meister S1 wheels

18x9 +15, 18x10 +20


Two Piece Work Meister S1 Black face: 21lbs each

Forged Center, Forged Rim, Curled outer lip edge for extra strength, stepped lip for added rigidity as well. This is their Motorsports Bred wheel. Hollow Spoke Center Disc.

Love them. I sent them my brake fitment and they cross referenced with any wheel I wanted. Never have i gotten that service from any other Japanese wheel company. Only from like Fikse, Kinesis, etc....

Lastly, what particular functions do you have for this vehicle? What wheel did you have in mind? I might have some suggestions for you based on your answers.

 

Oh, all my baseline fitments are based on maximum allowable front spacing of wheel in Front, and maximum backspacing of wheel in rear. Hope that makes sense to you guys. Since I've done so many FD "MAX" wheel fitments, hehe, I just use offsets relative to widths that i've used before.

 

Also as a frame of reference, you cannot use the stock wheel's offset to do these types of measurements. That will only be a constant variable if the "aftermarket" wheel you are using is the same width. Coincidentally the FD aftermarket wheel's ideal offset and the factory offset are one in the same. This does not happen on to many applications.

If this doesn't make sense to you please speak up and i will be glad to provide and example via math. Please read thru my comments slowly as i'm no english major, i'm an out of date E.E. who sells car parts. lol. Watch out for the run ons.

 

Rishie, I am planning on road racing, and need to make the most of the space in my fender wells. I am personally running feed front and rear fender treatment (+20mm wider front, 38.1 wider rear with original rear 1/4 panel modified for the widebody, of course). I would like to run the widest possible up front and in the rears. IIRC 18x9.5 would fit in the front, and 18x10.5 would fit in the rears, however I think there maybe more room. I would prefer the Work Meister S1 with a Black Face, but would also like any suggestion of lightweight wheel from Work.

For suspension works, I of course have the Function X, and would need the fronts to clear the Inch up 2 kit. Actually, come to think of it, I think I will give you a call today, lol.

 

YO Chris,

for about another 1.5 on rear fender and being that 10.5 is max for stock modified fender, we'll add those two together and get about 12.0" wide in rear. Offset for that would be 45-18 = +27 or so offset. Up front go with the +20 or +22.

Thanks, Rishie

I have lots of Meetings today, some Japan peeps are here. Try calling I just can't guarantee I'll be able to talk much.

 

Wait, wait, wait Rishie me and RedR1 have the same width front fender why would a 18x9.5 +22 work for him

 

I was just on FEED's website and for the rear fenders(20mm wider) they recommend a 9.5 +24 would this not be the same for the front also? That being said a +22 should not be that much different, right?
