Does anyone know if the 1st gen tc stock rims will fit on our 2nd gen?

It won't, it has a different bolt pattern at 5x100 while yours is 5x114.3.

Damn i was hoping they would because i found a set for dirt cheap on ebay and i figured they'd look way better than steelies ha. thanks for the measurements though, that will definitely help me out

Use your current stockie 18"ers... and buy some new one's when the sun comes back around.
Tha's what I am going to so. Save my money when the snow falls.. and go shopping for her when the weather starts to warm. Hopefully the rear camber problem will be solved by then as well... so I can stick those inserts in my babies shoes and make sure they last a while instead of wearing on the sides.
