I'm looking to buy forgestar f14s and don't want a too aggressive fitment. I would like to get 20x9 or 20x9.5 front and 20x11 R with a 255/35/20f and 285/30/20r.

So far I'm going to keep the stock height suspension and camber. I want offsets that are close without rubbing and not quite flush, what offsets should I go with? Please help!

Talk to getyourwheels. They will set you up.
http://www.the370z.com/wheels-tires/...p-concave.html Use this to calculate offsets. Custom rims, wheel tire packages for your ride - RIMSnTIRES.com This is a good read. Wheel specs without having to use spacers |

I think its accurate. Just measure your stock rims and how far they are from the edge of the fender (~20 mm I think) and then use the calculator to give you the offset that gets you close to the rim.

+30 front will be sunken in a bit (3 mm), but you can use a slightly wider tire to to get it more flush.
The + 28 rear will be slightly more sunk in then the front (8mm), so a small spacer might be needed. |

According to the rimsNtires.com offset calculator I can do a 20x9 +33F with a 245/35/20 and a 20x11 +20 R with a 285/30/20. Front will extend 14mm and rear will extend 15mm. But the Nissansportz.com offset calculator says the front will extend 14mm the same as the rims and tires offset caculator but the rear says it will extend 23mm, so 8mm more than the other calculator did, doesn't make sense!

Thanks! I think the sport wheels are 19x9f +47 245/40/19 & 19x10r +30 275/35/19 at least 09-12 my13tires are the same maybe the offsets are different, I'll see if I can find anything on that.

Anyway here as some numbers with different tire options and offsets. I ran your desired offsets and getyuorwheels recommendations. The difference in tire numbers is obviously by how much the tire sticks out past the lip. Fronts: 255/35/20x9 +30 Will stick out 22 mm farther then stock. Wheel diameter 686 mm (679 mm stock) 245/35/20x9 +30 Will stick out 17 mm farther then stock. Wheel diameter 680 mm (679 mm stock) 255/35/20x9 +20 Will stick out 32 mm farther then stock. Wheel diameter 686 mm (679 mm stock) 245/35/20x9 +20 Will stick out 27 mm farther then stock. Wheel diameter 680 mm (679 mm stock) Rear: 285/30/20x11 +28 Will stick out 7 mm farther then stock. Wheel diameter 680 mm (675 mm stock) 295/30/20x11 +28 Will stick out 12 mm farther then stock. Wheel diameter 686 mm (679 mm stock) 305/30/20x11 +28 Will stick out 17 mm farther then stock. Wheel diameter 692 mm (679 mm stock) 285/30/20x11 +15 Will stick out 20 mm farther then stock. Wheel diameter 680 mm (675 mm stock) 295/30/20x11 +15 Will stick out 25 mm farther then stock. Wheel diameter 686 mm (675 mm stock) 305/30/20x11 +15 Will stick out 30 mm farther then stock. Wheel diameter 692 mm (675 mm stock) 285/30/20x11 +23 Will stick out 12 mm farther then stock. Wheel diameter 680 mm (675 mm stock) 295/30/20x11 +23 Will stick out 17 mm farther then stock. Wheel diameter 686 mm (675 mm stock) 305/30/20x11 +23 Will stick out 22 mm farther then stock. Wheel diameter 692 mm (675 mm stock) Hope this helps. |
