trying to decide on wheel sizes
 

just got my 370z about two weeks ago and im looking at , some "petrol vengeance" wheels , i was looking at getting 20x8.5 in the front and 20x10 in the rear , do u guys think it will have an aggressive enough look , with the 370's wide rear flare out ? i dont want them too look to sunken in . or should i just start looking for 20's that come wider than 10 inches ? and if so can u guys throw out some suggestions of brands ?

The main factor for fitment are the offsets. Can you list the offsets that you are considering?

8.5 front is a little weak, the stock RAYS wheels with the sport package are 9 inch wide in the front...I would suggest going with that width in front if you can.

ummm what do u mean by offsets ?

offsets are where the hub of the wheel is located on the rim....... right???

9-9.5 fronts and 10-10.5 rears.....something like that

so what would be a good offset, i want the wheel as close to flush with the rear and front bumpers as possible , if i get 10.5 in the rear and 8.5 in the front (the rims i want only go 20 x 10.5 and 8.5 ) so i gotta get 8.5's in the front

this will explain offsets...if you do a search a couple people have posted calculators to give you a tool to calculate what offsets you want with what width wheels. Once the wheel width changes, the optimum offset changes as well.

the rears can go up to 12...... get 9.5 fronts

20X9.5____255-30-20
20X12_____305-25-20


that looks super good.....i dunno about offsets though

stock sizes are
fronts 18 x 8.0 with 225/50R18
rears 18 x 9.0 with 245/45R18

and for Sport with the BBK's
fronts 19 x 9.0 with 245/40R19
rears 19 x 10.0 with 275/35R19

and stock offsets on the sport package are:

front +47
rear +30

for reference, I ordered forgestars in the following sizes:

19x9 +24 offset front
19x10 +20 offset rear

this will bring the wheels out to be a little more flush with the fenders

^^ with ur specs, his should be

8.5 fronts (i prefer 9.5 but it's his Z) with +30

and rears 10.5 with +14


something is off here....lol


you try this with ur specs of 19x9 +24 offset front & 19x10 +20 offset rear
the stock specs are too sunk in.

Wheel Offset Calculator

go 10in front and 11 out back

Rear with 10.5 should be +26 mm if you want to match the 19x10 +20
front with 9.5 would need +18 mm if you want to match the 19x9 +24..+20 would probably be pretty safe

wait a second, let me try again

for same outer postion

8.5 fronts would need +18 and inner clearance would be 12mm more....no lip probably

9.5 fronts would need +30 and inner clearence would drop 12mm

10.5 rears would need +26

lol it wasn't this complicated when i got my zenetti's for my g35 , i just went out and ordered 20x8.5 and 20x10 , iv been looking around and not many brands have 20 inch rims over 10.5 widths

ohh and another question i have is why , on the rear tire aspect ratio , do people get a smaller size ....wont that mess up the look/drive ? ie - 30 vs 25

front -255-30-20
rear - 305-25-20
