550 vs regular 540 = 550 better

550 vs 540 4 pole = 540 4 pole

550 4 pole vs 540 4 pole = 550 4 pole

Only downside (if you race and your track cares) with a 550 4pole is that it is not roar legal last time I checked...........


On that note, I'm just itching to get back to the track, due to working almost a month straight I haven't been in awhile and I really want to try my new setup with the help of Marcus and a few others........ Hopefully I'll be able to try out my V2 center diff again and not have any problems (my fault for wrong installation most likely) with it...........
