I have been looking at some brake lines for my car and the ones from Jbodyperformance.com  They seem to be really nice but I was wondering what the drawbacks would be to running just the front lines as SS and the rear lines stock.  I already have some axxis ultimate pads to throw on and I fugred that I would throw these on while I was at it.

No drawback.  The only rubber in the rear is about 3" long and not an issue.
 
 
Cool deal. Gotta love saving money!
