This is my first post everyone so if I mess up. My bad. Well. I am planning on doing a full drive train swap to my 240 Volvo down the road. My biggest problem I have is which axle to use. The My car is a daily driver but want to turn into a Rally Car. I have looked around and understand both aspects of them to some extent. My car will have anywhere from 450 - 600 HP and 500 TQ when done so dependability of IRS is questionable. That's where a 9 inch Ford comes in. I just don't know. :smash: Thank You for any help. Looking foreword to many forums. (I'm Not Crazy.)
