GTH064 Posted March 20, 2013 Report Share Posted March 20, 2013 Just curious to know if any of you GTS owners have swapped out your existing gears for an upgrade, if so which did you get? How does the upgrade feel compared to what you had? Cost? Link to comment Share on other sites More sharing options...
lbj Posted March 20, 2013 Report Share Posted March 20, 2013 Are we talking differential here? I had the 3:73 put in mine. It's a bit snappier off the line but makes me shift through the gears sooner. Link to comment Share on other sites More sharing options...
GTH064 Posted March 20, 2013 Author Report Share Posted March 20, 2013 Was that Shelby installed during build or done after you got the car? Link to comment Share on other sites More sharing options...
lbj Posted March 21, 2013 Report Share Posted March 21, 2013 It was installed by SAI at the time of the build. Apparently it isn't a huge deal to have a dealer do it, but it will require an adjustment to the computer to make the speedometer read correctly. I'm talking Mustangs with manual trannies. My base car had 3:31s. The difference is very noticeable. I would have liked to have tried 3:55s, halfway bewteen stock and what I have now.
