Wheel Offset Discussion Thread... How far can we go?

[boosted180]

Someone please help me decide. I'm ordering Forgestar 18x9.5 front and 18x10 rears. Tires will be 255 40 18 F, and 285 35 18 R. -2.25 camber front and -1.75 rear.

What offset do I need for a flush or close to flush fit??

I've read wildly different numbers. Some guys are saying a +30 for the front will be flush and others are flush at +20. By my rough calculations, it should be closer to +20. For the rears, I figure about a +16??

The only problem with the fronts is that the semi-concave only goes to +26. The don't have anything lower than that. So should I go deep concave in the front and super deep for the rear? Or just stick with +26 in the semi-concave and it should be ok for the front and deep for the rear at +16? Or if I go with 18x9 in the fronts, what offset do I need? Something around a +28?

Help me decide!

So about to pull the trigger on some new wheels. Advice on my current plans?

Currently Rays w/ stock tires
19x9 +47 (+27 w/ 20mm spacers)
19x10 +30 (+10 w/ 20mm spacers)

Planned CSL Rims
19x9 +30 (+25 w/ 5mm spacers)
19x10.5 +20 (+10 w/ 10mm spacers)

I assume if I want the same stance I currently have that I will need smaller spacers with the new rims, correct? ET 30 front and ET 20 rear would be fairly tucked in, i think… Thoughts?

For reference, most guys with Volk GTS wheels are running 19x9.5 +17 and 19x10.5 +18. TE37 owners with the same wheel widths and diameters as mentioned, however, run +22 front and +12 rear. For your Forgestar 18x9.5 front and 18x10 rears, I would get between +22 and +15 front, and maybe something as low as +6 in the rear since you intend on running 18x10 wheels.

I'm running 20mm front and 25mm rear spacers on my stock Rays so I know where you're coming from. With your new setup (plus the spacers you mentioned), your front wheels will stick out by 2 mm , which I think would look better. The rears, on the other hand, will stick out by 6 mm, so it's like running 26 mm spacers on your OEM rear Rays.

I just put down a deposit for a set of Work Emotion CR2P wheels in the 19x9.5 and 19x10.5 sizes. However, I'm still undecided on what offsets to go with. I understand most run the +22 front and +12 rear offsets for TE37s, but I'm pretty sure +17 will fit nicely up front considering some guys have GT-S wheels with those offsets.

The question is, what offsets would you suggest I get? I'm leaning towards 19x9.5 +17 front and 19x10.5 +12 rear. I'm lowered on Swift springs and do not intend on getting camber arms, or anymore negative camber. Regarding tires, the wheels might eventually end up on my 350Z so I'll more than likely get 265/35 and 285/35.

With that said, what car/wheel combination do you prefer? A 350Z on TE37s and 370Z on CR2P, or a 350Z on CR2P and 370Z on TE37? The 350Z is a bit lower so I'm guessing the "flashier" CR2P would suit the car better? I could then just put the TE37s on the 370Z. Thanks guys.

Thanks for the reply. I decided to just buy the rims and throw them on first. Then I can safely figure out what spacers to buy.

The whole new problem is finding the right lugs for the new wheel, lol.

Looking for some advice. I'm looking to get a set of Gramlights 57FXX in 19 9.5 and 19 10.5. I have no idea on what offset I should go with. I currently have stock sport Rays with 15mm spacers in the front and 20mm in the rear. Thanks in advance for the help

Personally I would go 19x9.5 +25 with 19x11 +18 but you will still probably need a 10-15mm spacer on the rear to flush it up. It just depends what tire sizes you're going with and if you plan to stance and flush or if you want meaty tires.

I am currently running stock sizes for the front but have 285 in the rear. I am lowered on Tanabe coilovers. But I am looking to have it sit flush. Will I still need to keep the front spacers or will it be fine with just the wheel offset?

How would these specs work on our Z's?

19x9.5ET10
19x11ET-2

You'd have to be slammed and run negative camber. put a 285/30 or 295/30 around the rear and you could be ok at a low ride height and a decent amount of negative camber.

With a good drop, fronts should be ok. I would not run wider than 245/35 on that front wheel width and offset. I have a that size on my 9.5" front wheel and it's flush. you will clear the front with a good drop at 1.5-2.5 degrees negative camber.

Hello,

I bought two set of rims from two separate ppl from this forum.
First set is work miesters sp3, 19x10 -2 245/35/19 and rear is 285/30/19 -7, very aggressive. I am lowered about 2.75 running -3.5 camber all around.

I am thinking about changing it up to forgestars for a bit. tires are 255/55/19 ALL AROUND. FRONT IS 19X10 +22 AND REAR IS 19X11 +0. YOU THINK WITH THIS SET UP I CAN GET MY ALIGNMENT MORE IN SPEC OR WITHIN OR CLOSE TO SPEC?, THANKS . MISESTERS ARE CHEWING MY FRONT TIRES UP.

Hi everyone,

Quick fitment question. I have just received my set of Work Meisters for my 350Z. Clearance is fine with my brembo's, 19x9.5 +24 (R Disk) and 19x10.5 +23 (O Disk). Have heard different stories about the clearance on the 370Z and akebono... brakes are bigger on 370Z?

Any rough fitment advice on whether these could fit the 370Z would be appreciated - will upgrade from the 350Z to 370Z in a few years.

Cheers,

[Ghost116]

Any help would be great, almost have it narrowed down for spring. Work emotion cr2p step lip. Front 19x9.5 +20 I think it's the a disk (clear bbk)
Rear is what I'm deciding on, looking at sizes similar to rusty 19x12 +20-25. I want to run a 305 out back with camber within factory spec or dam near. My thinking is rustys running +28 with a 325 on stock suspension. So the 305 with -5 more offset should put me just a little more tucked then him? ( to allow for closer to factory camber specs)

Does that sound about right?

[Ghost116]

Oh and 3fiddyz work may offer template or contact them they should know if no one knows for sure. But from what I've read it should clear akebonos (on sport models)
