another pic

 

actually the offset might be 20 I'm assuming... based on this pic...

 

but the rim size is 20x9.. so idk if that is the correct offset of 20.. man I'm confused.. can't believe finding a offset for a rim is this difficult...

 

so if the offset is indeed 10 is there away to increase it?

i found this site and put in all the numbers and the site said it was fine

That may be the offset for the blank and it may have been machined down to its' current offset. A lot of wheels come with a aggressive intial offset so it can be cut down to various offsets depending on a particular vehicle fit. Like my 20" Nuteks are stamped ET20 but have been cut down to +40 & +45.
The other pic you posted is the wheel size, just labeled a bit different w/ the 9 & 20.
Hopefully yours have been cut down to a more sedan-friendly offset, you can do a test fit on your car and see how it looks.

 

if your're a so cal local I have a set of tein Stech springs already on sport shocks if you want them i used them for a month and they have just been sitting in my garage ever since

 

One last thing... What should be the psi for these rims on my car?...

Why did you take them off after a month?

 

35psi is good for most G setups.

 

I usually keep it around 35-37 psi

I took them off because I wanted more drop and missed the firmer ride of coilovers!

 

Just get the right offset the first time closer to 35mm-45mm. That way with your X you could add GOOD spacers maybe in the rear 5-10mm to fill out flush based on drop and tire width. I wouldn't to over 15mm and always buy replacement studs of over 10mm spacer.

 

i have the same car as you and yours looks great! im in the market for some springs, besides the springs were their any additional things you had to do?

 

Got them on fellas they stick out a little but no rub rides nice
