15x9 dekagram with 245/40/15
 
I only saw one car with a similar setup and it wasn't with the rt660 falkens. So I thought I'd throw these out there. I only have rolling front and rear, no pull. Running 3.5 f 3.5 r for camber. No spacers. Took it down some back roads at speed, and with bumps and I don't seem to encounter any rubbing. Track time will tell, but everything seems good. Just Thought I would share if anyone was looking to do this setup.

I stil have my rpf1's 15x8 et28 with 225 45 nitto nt01's, curious to see if I notice a difference on track. On the street they feel good but that doesn't count.... :)

Can i get some details on your driveway material? Details of what it is, cost to lay, etc. It looks awesome.

The car is cool, but the driveway is rad.

Ha i have no idea what it is called. I'm sure my Brother in law would know. It was here when we moved in. I will warn you it hurts like hell to walk on it barefoot. Pretty much like walking on stones. It does look great tho.

Looks like exposed aggregate. It's sprayed/ power washed after it sets.

Exposed aggregate. Hurts like hell on bare feet and will rip you open if you drag/kick your toe, you'll loose anything small if you drop it and is slippery as. In the wet it is 10 times worse.

Looks good!. Makes me want to go to 15x9.

Confirmed no rubbing on the track. Tires felt really good. Started at 28-29 psi. Got up to around 33 or so depending on the time. Seems like a real solid setup to run wide tires without having to do some over fenders.

I've been running 15x9 w/ 245's for about 4(?) years now on my NB1. I've had VR-1's and RS4's mounted and have had no fender rubbing with a flat roll on all 4 corners. I'm getting ready to mount some Falken 660's but I don't expect them to be any different.

Sorry to revamp this thread from last year. I planned to run Advanti Race Storms 15x9 ET35 on my NA with 245/40’s and Good win told me today that I’d need flares. WTF. I HAVE Spec Feals and -2.5 camber.

your car looks good.

No flares necessary

All of it.

I'm only running about 320whp according to RyanG's calculations. I'm out of headroom with these injectors and haven't installed the larger ones yet. I also need the next size MAP sensor to go higher than the 21ish psi I'm running.
