Heres my dilemma. I'm building a "race car" out of a Neon. I'm using a ford 9" for the rear axle. I want to use a spool in the rear rather than a limed slip diff. I alway thought a spool on the street = broken axle shafts. But several people I talk to said the car would be so light, that a spool would be ok to use. I'm looking for advice from someone that races or has experience with spools.
