Zdan,

offsets are measured from the centerline of the wheel to the mount pad, therefore you need to take into account the width of the wheel in order to achieve the same distance from the fender to the wheel.

I hope you do not take this the wrong way, but the width has to be taken into account.

OP, this is how you can calculate the distance from the wheel's face to the fender:

spacer needed = ((((old front Wheel width / 2) - (old wheel offset / 24.5)) - ((new front Wheel width / 2) - (new wheel offset / 24.5))) x 24.5)

front wheel:

((((8/2)-(50/25.4))-((7.5/2)-(55/25.4)))x25.4) = 11.4mm front wheel spacer

rear wheel:

((((9.5/2)-(55/25.4))-((8.5/2)-(65/25.4)))x25.4) = 22.9mm rear wheel spacer

Also, I had both the AP2V2s and AP2V3 wheels side by side and remember that the offsets were not the same. I cannot remember exactly but they were 1-2mm different.

Zdan,

I reread what you wrote and I understand that you gave your numbers wrt the tires. I did not check that ... as tires of different manufacturers tend to have different widths, so it becomes difficult to calc.

from reading s4play's flushness thread... i will have issues with 15mm in the front as V3s don't have dimples like V2s...

so... here is the setup i think..

V3s with oem tires 215 and 245 with 20mm all around...

now - where can i buy H&R Spacers (outside of CA - hate paying the sales tax)???

 

I got mine through someone I go through for most of my parts that's in Vegas(he's got a shop in LA and the parts in stock). No sales tax and no shipping. I ended up paying $280 otd.

 

if i run 15mm spacers in the front - i will have to either shave the studs or replace them with longer ones.

anyone have recommendations for either? i think i would prefer to replace the studs...

pros / cons???

 

with these calcs in mind, i finally decided to go with 10mm in the front and 20mm in the rear...

with 215 / 255 tires...

will post photos sometime next week of this experiment.

thank you all for you comments.

 

He used the wrong front wheel width though. It's only 7" and when combined with the narrower front tire you plan on running you will need a 20mm spacer to match your current front fitment.

 

 

thank you very much for catching that... i really appreciate it - owe you a beer at least.

now - i will be going 20mm all around.

 

I have 20mm front and rear with 215 and 255 on AP2V2. Very flush. It will be perfect. You wont need your lips rolled but it wont hurt. Good luck.

Oh yeah, i am running project kics for evasive motorsports. Have been for a year wnad no probs. I drive her pretty hard too. 500whp and 300+ torque and they are holding just fine.
