Think about it this way. Do you like your car enough to want it to be road worthy? I sure as hell want mine to be. Just fix it. It's hard to get dogies these days because most mechanics are too scrared to do it
Lol I loved prinny when I was 18 (I'm 23 now) and on p's driving a 250rwkw r33. These days it's just to drive pointlessly and hang with mates instead of going out wasting $200 getting wasted and then all you get is a massive hangover. But yea my car is too modified for prinny these days. Car doesn't ever see it on a Friday night lol
A 2 way diff is bloody awesome, You wont look back! It locks bloody hard and makes your stocker seem like a pos, It drifts bloody well with it, good at mountain runs. No complaints here.
Like someone said before, put in a 2 way, then when you sell the car put the standard one back in
