I have looked through and read about all of the stickys and threads for choosing new rims. I just want any input or confirmation that my choice will fit my 2002 Trans Am WS6. I am looking at getting the S107 Laguna Weld Performance wheel in 18x9.5/7.2 backspace/+50mm offset with the Nitto NT555 G2 285/40/18.
The laguna also comes in 18x9.5/6.4 backspace/+29mm offset and 17x9/6.8 backspace/+45mm offset, if my first choice won't work.

 

you should be fine with the 9.5 and +50 offset. i have 18x10.5 +50mm offset weld rts's on all 4 corners of my car and they fit perfect imo, tires are 295/35 nitto nt05's. you have a little wider rear quarters with the trans am over the camaro's too.

 

So now I am thinking of going with staggered. Still staying with the same wheel and tire but doing 17x8, 0 offset with 255/40/17 in the front and 18x10, +30 offset with 285/35/18 in the rear. Kinda like what the corvettes do.
