That’s kinda what I’m thinking too, ordered a Ford Racing iron Torsen diff. But the slower e.t. And mph are enough for me to stay with the tried and true Street R.
Well, it was an expensive experiment for me. Might be different for someone else though.
A little about the car. 15 GT VMP Gen3R 900whp, fully built 6r80 by PBH, 1c converter 3.55’s.
Last time out without built trans and converter it went 9.5 @148 with Street R’s on.
First pass with Hoosiers...
I just put them on some D5 beadlocks and will be testing this Friday. I was running 305/45R17 Street R’s on Racestars. They are significantly lighter with a very thin sidewall and balanced better than any M/T I have ever owned.
