Hey, I'm about to buy an eg with an itr b18c5 motor and tranny. The final drive has been swapped out with an ats 4.929. The rest of the gearing is stock from what I know. Can anybody tell me with a set of 205/15s what rpm I'll be turning at 70mph. I'm trying to see if this is practical for highway driving or if my teeth are going to be loose after an hour or two... thanks in advance.
