Has anyone raced using the Viscous type R200V in their 240SX?? I have two diffs, one with 4.37's and the other with 4.08's. The 4.37 diff has a clutch-type carrier, which I used at my last race in Seattle (needed 4.08's!). I'm putting in the 4.08's for an upcoming non-chichane race at Portland, but I think the LS unit is the Viscous type.
Any Pros or Cons of either??
