I've just upgraded to Fabulous Profound 20x9 +32 offset fr, 20x10 +32 offset rr.

From my observation, it seems that the 'best' combo so the wheels 'sticks' out there is ?x9.5 +22 fr, ?x10.5 +22 rr.

So for you experts out there, could you help me calculate the correct spacer size so I can get the wheels to stick as far out as possible, and of course I know I have to roll my fenders...

 

You might want to check out the Unofficial Rim/Offset thread. Its a few pages back in wheels/tires/brakes/sup forum. There are links to pics of rim size and offsets. About 3.875" is max outer without needing to roll. Which you are 1/8"(4mm) of an inch away from now!

You should post a pic and your stats of those sweet babies to that thread too.

 

I've done just that, and after calculating I found out the correct spacer size is 12.5mm (is that even correct?).

Can someone just actually help me calculate the correct spacer size based on that table?

 

Its hard to say what the "correct" offset is. Its based on personal preference. That's why the chart has links to pictures. Pick an offset that you like based on pics and we can help you with the spacer size.

Check the chart for the 10"/19's with an offset of 18mm. That will give you a very close approximation of what your's would look like with the 12mm spacer.


12mm spacer gives you 4-3/16 outer. Definitely a roll need there.

 

I have attached 2 pics showing the front & rear of my car.

From the pics you provided, I would really like mine to be the 10.5"/19's with 22 offset, definitely one with very aggresive stance and wheels sticking right out there...

I didn't know you were lowered. I don't think I would add a 1/2" spacer to that setup. I think you would hit the fender going over bumps. Seriously, you want it pushed out more than that???

If I were you I would measure the gap between the outer fender and your tire. That would give you the best indication of how big of a spacer you can go with. I would be suprised if it was more than a 1/4" or 6-7mm.

 

Umm...yeah...

The setup that I'm thinking about is to push it as far out so the tires is really close to the fenders, and since the rear well has some camber, I like the rims (silver) part to be inline with the fender...

I would appreciate if you could estimate the right spacer size for that setup...

Btw, zillinois, thanks so much for helping me!!!
