I think the offset is 32mm. The wheels came blank and were drilled to my bolt pattern
and shaved so that they fit flush.
It was really a custom install.

ok so a little about staggered setups on AWD cars.
Can it be done? Yes. Lots of AWD cars have them including the GTR, so what's the issue? well, if not done properly, a staggered setup can ruin a AWD system because the front and rear wheels are different circumferences. This means they're spinning at a different rate which causes the computer to think that either the front or the rear are always slipping. This can ruin your center diff. Now as long as you keep the same circumference in both the front and rear wheels, you can run a staggered setup.
2 different types of staggers:
1. larger rim wheel and smaller front rim such as found in the NSX and corvette (ie. 17x8 front and 18x8 rear)
2. wider rim wheel and narrower front rim (ie. 18x8 front and 18x10 rear)
So now you think if you go with the 2nd type of stagger (narrower front, wider rear, but overall same rim size) the overall circumference of the rim + tire will be the same and no problem? Yes thats correct, HOWEVER you will need to run diff sized tires as well, ie. 245/45/18 front and 285/45/18 rear. Obviously if you run 245/45/18 tires on both an 8 and 10 inch wide rim, the rear will have much smaller circumference because of the stretch.
Now if you run same rim + tire spec front and back except the offset is different to achieve that staggered look, this is perfectly fine and you wont have to worry about different tires as the rim is the same width and overall circumference still the same.
Hope this clears it up. Now for those thats going to order your own rims and not get a wheel shop to do all the calculations, here's a tire size calculator that tells you the circumference differences in different sized rim applications:

word has it is if you keep the difference under 6 revs/mile, it's safe enough for the AWD system. This however is not scientifically proven so do so at your own risk. Safest route is just to go with same spec rim + tire with diff offset.

Sorry...wife and I are expecting another baby and haven't had time to log on. I'm running 20x 8.5. DPE makes the rims. I brought the rx to their shop and they did some test fits to get it to my liking. The owner is my cousin and i can get sweet pricing...I am also planning on selling my current setup...so hit me up if interested.

As for wheels size and fitment. I went with a set of 22x9.0" front and rear with a staggered lip look. The wheels are 3 piece and the ET's are different front to rear. I lowered it with a set of Eibachs, but am a bit disapointed with the drop. I am running Dunlop 265/35-22 and the RX rides like stock, infact better, because you get a more plated feel on the road. I hope this helps your decision.

Thanks for posting the pics on 22's and that width. Gives me a little bit of an idea on how my 10's will look in the rear. Dunno if it's what I want. I think 10's will be too wide depending on the offsets. especially after the tires are on.

Hi guyz,
I am new member and would really appreciate your advice. I went throught the topic, but I dont really understand this wheel-stuff =)
We got 2008 Lexus RX400h with stock 18" Rims.
Its time to get new wheels with summer tyres, so I was thinkin about getting something more cool =)
Its my moms car, the color is White Matt - so I was thinking getting White + chrome wheels. Found some beautiful Eta Betas here in Czech Republic, however they are expensive and I know she's gonna scratch them really quickly, so its not worth it.
But I found these:
Dont have Photoshop pic done yet, but I believe they will look cool on white car.
Anyway my question for you is:
We will not be lowering the car and I need it to be still comfortable here on Czech roads (with so many holes). So I am wondering what would be better? 19" or 20"
Also if 19" what should be Rim size (8/9/10J) and what would be better? Use ET15 on rear and ET35 on front?
Also if 20" what would be best and what kind of Tyre size I should use?
Thanks in advance
