Hi all, I’m looking to purchase a set of apex VS5RS wheels with 19x9 et34 19x10 et40 , this seems to be the only set up available for IS in general. Was told this can be a very flush fit, and it can only work with OEM tire sizes.

does anyone have experience with this set up? Can I still fit 245/275 down the road on these wheels? Any advice is appreciated thanks.

 

Use online calculators to get an idea about fit. I looked at VS5RS spec, but i havent changed the wheels yet - but in short - yes their spec looks bang on. Details below.

Front comparison:

According to my math/findings, 245 is preferred on 9 inch, thats what I ran on previous car as well and it looked right (if only slightly tiny stretched) - basically it mirrors 235 on 8.5 inch

Similarly for rear comparison:

Again up sizing +1 to 275 makes sense.

If you look through the spacers thread here, I think people prefer 15mm /20 mm f/r as being "flush" not sure if we need more. So the calculator confirms front would be 17.6mm out and rear will be 26mm out. Sounds perfect? Probably, but I haven't seen it in person yet, slight variation in camber would change your view of "flush".

I want to love VS5RS, they have beautiful concavity, but something about side view throws me off as they are too "thin" on the spokes, as if they nearly disappear. Its a preference of course, but for sure they are one of my top contenders for looks.

 

Thanks a lot! do you think 26mm out in the rear would potentially cause rubbing? i haven't found any other aftermarket wheels that are in similar price range as the apex forged ones, BBS/HREs cost way too much lol

 

yea x10+40 might be pushing it too close, unless lowering/camber helps tuck in the top, hard to say from these pictures something to the tune of 5mm difference

i could never find more pics of this spec, esp the exact angle to see flush.
9.5+40 is probably more ideal/less chance of pokey, maybe someone with those sizes chimes in and posts exact angles.

regarding real forged wheels, certainly Apex wheels are attractive, esp with their replacement warranty, but they arent made in Japan forged by mountain gods wheels like BBS or the like.
I understand if you had BBS stock wheels you might want forged aftermarket, but my conclusion (after diving through the wheel rabbit hole) is that non-forged wheels, like quality made flow formed wheels from Japanese manufacturers (Work, Weds, Enkei, Advan, Rays Gramlights) are probably at least equivalent of made-not-in-Japan forged wheels like Apex, *for purposes of street driving*. Weight is fairly important consideration though, but again flow formed wheels may be light enough. My previous car I had Weds tc105n lightweight flow forged wheels and they survived street pot holes just fine for nearly 10 years, with a few track days where they werent subjected to anything drastic either. I wouldnt want to exceed stock weight specs though, but I got stock Enkei wheels anyway, and they are somewhat heavy or at least in line with most of "normal" aftermarket wheels of this size, so alright. Pros and cons.

 

yeah but I don't want to put square set up with ET34 in rear too it'll look more weird... i have the stock enkey wheels, flow form wheels work as well, I was just looking for a decent and nice looking wheels as my summer set up.

Yes you do not want to do square 19x9 setup, because you'll be losing 1/2" on rear, not a good idea for us given we need all rear tire we can get. I think Apex made x10 size for rear in that offset because they verified and that is reasonable.

That's why I moved away from Apex and am exploring 9.5+40 wheels instead. In fact I might just run 9.5 in the front, but I'm a little bit concerned about increasing front width by full 1" (might lose some initial turn in/responsiveness, which already isnt great on IS)

The "ideal" spec for Apex for me would be 9.5 rear, which they only make in non-forged VS5 18", I know that going down size wouldnt be poplar with the "looks" crowd, but I am rocking 18" winter wheels now and I can't say it looks awfully small, it actually looks fairly "beefy" with the right tire, the advantage is the ride is a lot more smooth, and tires will be cheaper .

So the choice is yours, and this is why its fun to mod, and if/when you get the setup the community would welcome your detailed pics of fitment/flushness, I know its fairly hard to find these tidbits of confirmation info.

 

will do! I'm gonna do a bit more research on this before committing to the apex VS5RS et34/40 set up. ET40 might still work better in the rear though compared to ET34 as it'll poke out less.with et34 in the rear poke out 32.4mm than stock rear.

 

I did a ton of research on fully forged wheels giving perfect flush fitment at stock ride height (flush with top of fender)

Cheap: VMR wheels are available in 19x8.5+35 and 19x9.5+45

Mid: Volk G025 can be 19x8.5+38 and 19x9.5+44

God tier: BBS RI-D in 19x8.5+38 or 19×9.0+42 and 19x9.5+45

 

For wide wheels with flush offsets I only found BBS CI-R Unlimited (flow formed not fully forged)

front 19x9+42 or x9.5+48
rear 19x10+48.5 or 51.5

Looks good on paper

 

Thank you, unfortunately the dealers I reached out to here in Ontario Canada was not able to source the Volk specs you sent, they look really good though and is probably my favorite so far in terms of the design.

 

I have the Apex set up now with 245 front and 275 rear. You do get a slight rubbing at about 75% steering input or more. 99% of the time no issues. No camber added just yet. I might try 255 35 to see if it is any better as the overall diameter might be ever so slightly smaller.

 

that's good to know, thank you. i guess 8.5 & 9.5 widths might still be better. id probably go with the rays G025s and give it a try.

 

just talked to a local rep and seems like for VOLK G025 the +44 is no longer available. I might look into TE37s in ET38 & 45

 

I have the Apex VS-5RS with OEM tire specs. Here are pix of how they look.







For the front, you can definitely run 245 without problem. For the rear 275 will poke out a little, unless cambered a bit more.

 

Thanks! is your car lowered? it does look like it'll be a tight fit if going with 245/275
