Will Gs300 Mk2 Take 18x8.5 Front And 18x9.5 Back ?

[katana92_uk]

hi guys

finally decided which wheels to go for just need some final help.

i have picked 3 wheels but specs are as below

8.5 J X 18" 5X114 ET35 FRONTS

9.5 J X 18" 5X114 ET35 REARS

and

5X114 8.5J X 18" ET42 front

5X114 8.5J X 18" ET42 back

and

5x114 8.5 X 18 ET32 ( FRONTS )

5x114 9.5 X 18 ET35 ( REARS )

three different wheels and offset is different on all of them . my question is if i go for any one of them above, wheels should fit ok to my GS300 MK2 yea ?

also somone said dont go 9.5 at back just stick to 8 all round or 8.5 all around ?

many thanks guys

To be honest mate your absolute best place to ask this is on clublexus.com as they tend to do this more than us - not sure about that comment about the rear as it would be better in the dry with wider rears, just be a bit more careful in the snow and rain from what I gather?

Anees had 10 inch rears on his and it was fine mate, think he said it was a more comfortable ride as well?

Actually have a nosey at this mate, thought I'd seen something like that over there:

cheers aido i have also posted on aristo net and club lexus

but what about offset 3 sets above which offset is best for my gs

[hodaz]

Offset is a bit of a personal preference I think. Personally I'd go as wide as possible so the bottom set would do me. Also liking the slight stagger on the offsets.

Hi i am running 295..35..18's at rear lowered down to 35 mm and it is fine unless you got a big load and 3 people at the back makes hell of a big difference on handling

@Ishy - tyre size don't mean anything if you if people get more negative or positive offset wheels to you due to clearance etc :D

what kind of look are you after? wheels poping out of the guards? wheels flush with the guards?

keep in mind stock wheels are 17x8 +50.

HKS D1GP aristo/GS300 as we know it (JZS161) runs 19x9 +38 Front on 245/35R19 tyres, 19x10 +35 rear on 275/30R19 tyres.

but yeh if your car is a daily drive 8.5 front 9.5 rear would be good.

don't remember to use search functions on forums though :D

GS wheels fitment

The stock GS 17" wheels, as far as I know, are 17x8 with 235/45/17. I have owned two sets of aftermarket wheels for the car, 19" VolkRacing AV3 19x8.5 +38 front and 19x9.5 +38 rear, and now I have the 20" HRE 540R 20x8.5 +32 front and 20x10 +43 rear. I would classify my 19" setup as a conservative setup as it doesn't flush totally with the fender but have zero rubbing issue, whereas with the HRE, the setup is very aggressive and is flush perfect with the fender, but has slightly rubbing which was fixed relatively easy.

The following are the wheel sizes that I would suggest for the GS (if you don't want to have a staggered setup, just put whatever for the front in the back). When I say the setup is conservative, it means you don't have to do any fender modification. When I say aggressive, that means you probably have to do the rolling or shaving. And in the case of professional, then some major suspension changes would have to be made in order to fit the wheel, and should be left to professionals hence I won't go over how here.

18" Difficulty

18x8 +32 18x9 +32 conservative

18x8.5 +38 18x9.5 +38 conservative

18x8.5 +38 18x10 +44 conservative

18x8.5 +32 18x10 +42 aggressive

18x9 +38 18x10 +42 aggressive

18x9 +35 18x10 +35 professional

19" Difficulty

19x8 +32 19x9 +32 conservative

19x8.5 +38 19x9.5 +38 conservative

19x8.5 +38 19x10 +44 conservative

19x8.5 +32 19x10 +42 aggressive

19x9 +38 19x10 +42 aggressive

19x9 +35 19x10 +35 professional

20" Difficulty

20x8.5 +38 20x9.5 +38 conservative

20x8.5 +38 20x10 +44 conservative

20x8.5 +32 20x10 +42 aggressive

20x9 +38 20x10 +42 aggressive

20x9 +35 20x10 +35 professional

** on 20" wheels for the GS, keep in mind that the wheels are out of spec so the overall diameter is off by about 6%. Your speedometer would be off, meaning that when the speedometer says 80mph, you are actually going at around 85mph already. Plus, because of the 1" larger diameter overall compared to 18" or 19" (with tires), you have to be careful with your lowering. From my experience, if you lower your car to 2 fingers, provided that you have the correct offset, you shouldn't rub (or very slightly) the top of the wheel well. If you go 1½ finger gap or less, when going over uneven road or dips, you will most likely rub the top part of the wheel well. Over time you will see part of the rubber wheel well flap got rubbed away. Moreover, with 20", you will rub when you put your steering wheel at full lock (either left or right) and mostly when backing up. This is due to the bigger diameter and when you turn, you rub the front and back of the wheel well (this is one reason why 20" are the biggest rims you can put on the GS with reasonable widths).

When it comes to tires for the GS, the following setup are preferred:

Keep in mind different brands of tires, even with the same profile, will be different too. So for very marginal setup (read: aggressive), the tires might provide the 1 or 2mm that makes all the difference. Tires like the Bridgestone SO3 and Dunlop P9000 are very rounded and "meaty". The rounded corners will help to avoid rubbing. On the other hand, from my experience, Nitto, Pirelli, Yokohama, etc... tires are very "square" so they might enhance the rubbing factor.
