Any experts can chime in? I'm thinking of upgrading to 20x9.5 and 20x10.5 SSR SP1's in the lowest offset possible that'll fit my akebono bbk's. I don't mind a little stretch and poke, but not too much. I want to have some meat on the tires as well...

Here's the chart for reference:

SSR seems to use their own system:
■Super Low Disk: 5/98～5/130
■Normal Disk: 5/98～5/130
■Medium Disk: 5/98～5/130
■Hyper Disk: 5/98～5/130

Can anyone help me out with this? So far, this is what I've heard:

20x9.5 +10 MD
20x10.5 +5 NR

How my car looks now:

 

how much tire do you want? You won't get much tire with those offsets, and you'll be looking at more than just fender rolling (unless you like tons of camber) with those rears

 

I would like to keep the 245/275 setup without going too much thinner. Maybe 235/265 is the lowest i'll go. I'm not looking to be too aggressive or stretched, honestly, just something that's flush with the widest lips possible without making my car super cambered out.

What about:

20x9.5 +18 NR
20x10.5 +11 NR

 

HD is SSR's code for maximum caliper clearance. Given the size and shape of the factory calipers, I would think that is what you'll need up front (I have not done too many setups with them yet though)

20x9.5 +12 HD
20x10.5 +18 NR - not sure if it clears the rear caliper, might want to check with G37 owners

 

R u referring to HP for the hyper disc? Those specs do seem the most reasonable... It's starting to make sense a bit more now. Rear caliper is definitely not that big, so I'm pretty sure NR should work...

 

yes sorry, I meant HP

if you need 'em, let us know

 

HP for sure up front...
factory brembos might be able to get away with SL in the rear, but might need NR for your akebonos.
