Question 18x9 Rota G-Force vs 18x9 Advan RS

Not sure if this should go here or in the member gallery section..

I'm wondering if anyone has side by side comparison pix of a 18x9 Gforce and an Advan RS wheel. I was discussing the similarities and differences with my friend earlier. We both agrees the concave on the spokes is slightly more aggressive and the paint is nicer with the Advans, but I'm still curious to see side by side pix. So, if anyone has them, please post em up!

i dont have side by side pics, but i would imagine that the advans are just made better and will be a couple of pounds lighter.
that being said, they do chip probably just like rotas from regular evryday road debris.im on my second set of advans and i would give paint quality 8/10.for the price you pay, they should be 10/10.

Yeah.. I've seen plenty on Advans chipped up pretty bad. I'm surprised Advans aren't forged.. just cast.. so they can't be that much (if at all) lighter than the Gforce.

To be honest... the Advan RS is made with a similar casting process as the Rota Gforce. I had a new set of Advan RG2's for a short time, and I've had a new set of Rota Gforce. The paint quality is pretty close also. The weight difference is a just little bit. In the end You are going to have that nice feeling of having a genuine set of Advans, but the look will be nearly the same. If you have the money then no doubt spend them on a set of Advans, or you could afford to buy two sets of Rotas and save a little more for seasonal tires to switch wheelsets.

Agreed. ^^

I'm really just wanting to know if the concave of the spokes are different. Some member pix of 18x9 gforce's look identical.. where others look less concave than the authentic RS wheels. Maybe Rota has two different offsets for their 18x9 gforce? I'm pretty sure they are all +30 and the Advans are +29.

my 17x9.5 (+35)advan rs's have a few chips in them. I think the ridiculous concave is why. also i had a some what stretched 255 on there before. I think with the current 275's they will get protected a little bit more.

The concave is identical from what I've seen when comparing the two in person. The Rota G-Force does come in 18x8.5 +48 fitment which still has concave however it's a lot less than the wider 18x9 model (you may have been looking at this model). The reason you commonly see paint chipping with the Advan RS/Rota G-Force is because of the wheel design. The spoke protrudes passed the face of the wheel and often will contact any debris on the road. It's pretty common occurrence as seen in this thread on EvoM

+1 Josh summed it up 100%

I'm so torn between getting 18x9 Golf Gforces for my STi or wait for the 17x9 Gold Grids...

Yeah the chipping is just a result of normal conditions coupled with the spokes sticking out past the edge of the rim. Unavoidable.

I have a set of the Advan RS 18x9 +29's and am the person the OP is referring too. I just got them and haven't seen anything yet; only been a week so far. If I do I will probably be disappointed, but I can't do anything about it and it looks like everyone is in the same boat - evo thread.

I'll probably get back on some forged wheels eventually I bet. I mean I just liked this look so I went for it. I don't track the thing. It's all for looks and the fact that I'm part ricer so I had to get the real JDM thing. I'm not really down for the whole imitation thing, but to each their own, not knocking anyone here.

Great points Josh.

East coast if different though. You guys, Dan/Josh, out in Cali have it nice and can role on nice wheels year round.

My seasonal wheels are my stock BBS with A/S tires (damn snow and excessive DE salt), haha. They do the great job and look GOOD too. Better than Rota options IMO.

Not sure if it matters, had the Advan RS on my STI (18 inch) and they only weighed in at 17lbs. Pretty light if you ask me. Not sure what the Rotas weigh?

^^ I was under the impression that 18x9 Advans usually weight around 20-22lbs.

It's definitely not that Alex.

The Fizz thread, which you can go to now in vendor wheel FS classifieds, says 19lbs.

I'll look on my boxes too, but they felt slightly heavier than my Gram Lights which were in the 18 lb range. (18x8.5)

he rays were the 57F's right? So they were forged and 1/2" thinner. If they were 18lbs, I bet the 18x9 cast RS will easily be 21lbs+.

Here's the thread I mentioned: http://forums.nasioc.com/forums/show....php?t=1795854

And if you want light wheels buy some Voks or Enkei's or something. The Rota's, as we've confirmed, are heavier than the Advan's so even if you get those it's not like they're lighter. That's more of an issue of how much you want to spend.

I'll check the box though.

yeah, no doubt the rotas are heavier.

i checked wheelweight.net and they are listed as 17.7lbs for the 18x9. i kinda doubt that one.. but its definitely leaning towards <20lbs.

18x8.5

I think that is what they were... not 18x9

Sorry about that

I really don't remember exact weight, but I really think it was 17.4lbs

Enkei makes alot of wheel companies in Japan

essentially the Advan RS are higher priced cast wheels... they are made just like the RPF1's, but cost a good bit more. You pay for the Advan name more than anything.

ADVAN Racing RS Wheels sizes and weights (mass)

17x7.5 = 14.7 lbs
17x8 = 15.4 lbs
17x8.5 = 15.8 lbs

18x7.5 = 16.5 lbs
18x8 = 16.94 lbs
18x8.5 = 17.38 lbs
18x9 = 18.3 lbs

So for a current model WRX the Hitachi rim weighs 22 lbs plus Dunlop SP01 = 25 lbs for a total of 47 lbs

OK to put this into context - I have ordered a set of 18x8.5 (48 offset) RS and paired them with Dunlop Sport MaXX RT 235/40R18 - this tire is Dunlops latest offering and is very light - 22 lbs UTQG 240

This combination saves me 8 lbs of rotational mass per corner and using the the Manthey equation is broadly equivalent of removing 190 lbs of mass from the car or giving it about 2.5 kw per wheel (also improves handling, suspension response, brake response, reduces drive train losses and general wear and tear).

The ADVANS are a very strong wheel, you pay for the strength, design and light weight - realistically Rotas are not in the same league
