Im looking to fit 305 all the way around on 19in wheels on my 2017 SS 1LE

Ive seen a lot of different numbers going around about offset and fitment however I'm lost and need help.

What wheel width and offset do you recommended? (I don't want to have any poke if possible.)


Special Notes:
- car will be lowered on BMR lowering springs
- car is always setup in track alignment
- thinking about doing camber plates and the rest of BMR adjustable suspension parts (however I want to be able to have the fitment without these parts)
- car isn't a daily driver only comes outs for track days, auto cross, canyon runs and the occasional car shows.

The help would be greatly appreciated.

Right now the fitment is 19x10.5 14mm up front and 19x11 43mm (37-43mm) out back.

You are going to have some poke up front. Only so much room up there.

I've seen a couple people on here that have done modifications to the struts, does that help and does that change the fitment.

I've got to be honest, I had 19x10.5 and 19x11 305 Nitto NT01's on my car and it changed the dynamic of the car so much that I ended up going back to the stock wheels and tires. I think there were some other factors at play here, so I have been trying something else recently. With that said, between OEM and the first 305 set up, the stock G3's/wheels were a ****ing blast to drive on.

I understand, I want to try out a square setup my self after driving a Z/28. After looking around I may just stick with a 285 or possibly a 295.

Doing a square setup is posisble for the tires, however for the wheels itself it will be staggered offsets.

19x10.5 ET 14
19x11 ET 36

or

19x11 with staggered offsets

Do you have any photos of the fitment of the 19x10.5 ET 14 upfront?

Check the link in your other thread that another guy posted.

Is that your same setup correct, I've seen to many numbers now!

[PK Auto Design]

Correct the other thread shows a 10.5 ET 14 upfront

Its also something MRR has done for the FS01 for a few setups we have done like for Sean and Ominous as well.

We do Forged wheels now for track setups in 10.5 fronts and or 11" fronts so its doable.

Do you have a recommended wheel setup for AutoX that would stay legal in A-Street and allow a 305 square?

What are the guys that have 18x11 up front run?
Can't find the thread.

I answered this in the 1LE subsection FYI.

I highly doubt anyone can fit 18x11" up front easily without any major change to the struts or going with ZL1 fenders. I tried to fit 18x10.5" wheels (+22mm) with 8mm spacer and it was still rubbing on the lip slightly. The problem is the height of the where the wheel lip sits. It touches a bit more than the 19" wheel even with the grinding on the strut tabs on my car.

I will most likely order some custom forged wheels with ideal offsets in 18x10.5" and 18x11" sizes as 18x11" sounds like a hard fit (even with the Multimatic suspension I am planning to get) It would be great if I could
