I currently run 225/40r18s, at the track last night other rex pilots were telling me I should go back to stock 16s for dragging. Honestly, most of these guys now s@#t about mods. Ohh, they talk like they know, but I ask them if they go online, like to this site or the others, they all said no. One dude cracked his a/m headers and blamed it on the txs utec. But he had no guages other than boost, and 22psi out of the stock turbo. So, I ask y'all are 16s better than 18s
