Okay, here's the deal. I think i'm decided on doing a T-56 instead of a TKO. What install issues might I expect to face with this change aside from the drivesaft length? Also, in your experience, how much power is just too much for the street, and what's just right for street and track use in your opinion? (I'll be running 12" wide simi-slicks through the new IRS if that matters) Thanks for reading and contributing!
