Hi guys, I need a little advice. What offsets do I need on a 19x8 up front and 19x10 in the back? Also, has anyone run 20's before?

 

Kel RX-8 has 20's I believe...and just off the top of my head, with the 19x8 you could probably stay close to the stock offset (+50) with no problems, and with the 19x10 somewhere in the +30 range would likely be good...but, I'm just learning about this stuff, so I could have my gigantic head up my gigantic **** :D

 

Go with the 20's, it will look sweet!

 

Just the opposite in fact. the wider the wheel the closer to the stock offset you need to stay. the rim diameter dosn't effect it untill you choose tyres that have a larger overall diameter than the std 18"

for std offset on the 19x10 you will have an extra inch of rim hanging out from the std rim width and 1" extra on the inside. you might have to roll the rear guards and check the shockabsorber to stock wheel clearance. if you don't have 1 inch you have to change the offset.
