I am about to purchase a second hand Rota G-Force and would like to know the fitment on my BLACK 2006 IS250 AWD. I plan on keeping the stock height.


Rota G-Force
Front and Rear:
18x8'5
Offset - 48mm
Hub Bore - 56.1mm

Tires I plan on buying for the rims:
245/40/18

My question is a) do I need to bend the fenders at all b) will I need spacers c) any opinions you may have for the look/fit

Your response is much appreciated!!

I do know that AWD's us a square setup which is the same wheel width all around.
those tires are going to be too wide up front. Most use 225 or 235.
Do you plan on lowering? If you don't then you might not have to roll the front fenders.

I'm actually not set on 245 just read on the forums that it is a popular choice for 18x8.5. No, I do not plan on lowering it.

For one the wheel hubs on our IS's are 60.1mm and the 56.1 hub bore on those are too small of hole in the center. 56.1mm is Honda and WRX hub size and you don't mention if the lug spacing is 100 x 5 which it usually is for 56.1 or the required 114.3 x 5.

Thanks for picking that up Harper7! The ad only states 114.3x5 actually. I will confirm the size for hub bore.

If it is 73.1mm is it possible for it to work?

Found some details that may be for these wheels

Yep, as long as it's bigger then 60.1mm with a 114.3 x 5,then it will work. They do make those wheels with the smaller bore too so you'll have to verify...... http://www.ebay.com/itm/18X8-5-ROTA-G-FORCE-WHEELS-5X100-RIM-56-1-HUB-GUN-METAL-/330587188034?pt=Motors_Car_Truck_Wheels&vxp=mtr&hash=item4cf8882b42

Yes, will definitely confirm before making the 1 hour trek tomorrow. Really appreciate your responses.

I'm set on 40 due to the bad roads in Toronto but for 18x8.5, do you know what size is recommended? 225,235,245. I really don't have a preference... clearly a newbie at this lol

245 is fine as far as width goes, but a 245/40-18 is ~3/4 of an inch bigger in diameter as well. I'm guessing you'll be ok, or have very minimal rubbing at stock height.

If the seller is in the area, ask for a free test fit AND then offer cash thereafter.
