Advice on Swap to Dot 5 - New MC

Don't believe everything you read on the internet, the only real advantage of dot 5 is an increase in boiling temperature which is required for road coarse continuous braking and you will probably never need.
When swapping components stay with the factory pieces and you should be fine.i.e. take the front brakes off the car that you got the rear from.
As AJ says, too much braking in the rear will cause the rear to lock up first and then you will spin..it's physics.
I would go mopar discs up front before any other changes with the proper donor car pieces.The only knock on Mopar brakes is their power booster has no feel and is too efficient.In even a slight panic you will lock up everything.
I know a family of skunks that will verify this!
