the concave face is what you're talking about, i'm assuming. because the rears have a lower offset thereby giving you a concave face, it will look slightly smaller. unfortunately thats how it'll look.

Your tire is available in 285/30/20, which will make you overall diameter the same as the front. That is your only other choice for the rears. Or get a smaller tire for the front.

here you go, found the name, Savini Black Di Forza BM4 BM-4 Titanium (Concave) i will see if the shop is kind enough to replace the ones i have for the ones you are suggesting, 285/30/20 so that at least it looks even...

Keep in mind that stock sport set up the front is 679 mm and the rear is 675 mm. So even stock it is not the same.

but on the stock wheels you dont see that much of a difference as you can see on these aftermarket ones, do you suggest i try to see if the shop upgrades the rear wheels only to 285 or 275/35/20? would that make a big difference?

thanks Cooltoy, appreciate the education here...

Yah, 14 mm difference now vs 4 mm with stock. I would probably go with 285/30/20. That gets you closer to stock numbers. But if you want to fill more of the gap, then you need to change the front to a larger diameter.

That is why I asked if you are lowered or plan to lower.

Looks like the wheel come in custom offsets. Front from +15 to +50, rear +25 to +50.

You sort of need to know what you bought. Somebody along the line has that info.

See if they'll replace the tire with a 285/30/20 and then after the drop you can measure your clearance to decide how much spacer you need.

Yes, since offset and tire size are two different things, deal with them one at at time.

Get the tire changed first.

Second, find out the exact offsets in the front and the back (maybe you can see then on the inside of the wheel when they take them off).

Once you know the offsets, we can advise on spacer size. With out the offsets it's a guessing game.

+1 for an 8.5" front that doesn't look that bad

I would just keep your rear tires and switch to 245-30-20's in the front

From the pics you provided it's not that sunken in the front so worst case don't get spacers until you see how it looks with different front tires.

to the point, I just had 20" 8.5 front (245/35/20) and 20" 10 back (275/30/20) Savini BM4. for some odd reason, I'm not sure if its just me but it seems that the back wheels/tire look smaller than the front. anyone has experienced this before and is there a quick not costly fix?

thank you all for your quick response.

Yoshi

it's your offset. you got it wrong. will fix it by adding a 10mm on the rear probably.

come on yoshi, you're japanese, no? you should know this.

hahaha... not japanese but for sure Z fanatic...

finally, the shop has been nice enough to take my tires back and will be getting me 285/30/20, so this should make a difference, no?!?

this forum dealio its awesome, better than an encyclopedia!!! after i get this tires swap, i will come back to ask for lowering education 101... but thinking on 1.0" front and .5" back...
