Why Summit? I got pricing from all of the prime suppliers. They all wanted to supply a complete kit but I'm sure they would have sold just the trans. I wanted to source all of my own stuff as I had most of what I needed (clutch pedal/linkage, driveshaft, bell housing, cross member). They all had their own proprietary clutch and I wanted to make that choice on my own. Like I said I believe they would have sold just the trans but Summit was cheapest with no shipping cost - just the $9.99 oversize fee. Not knocking the companies that supply these kits - I think any of them would be great to work with - Summit Racing just worked well for my situation.
