Great read. My 2010 SS will soon be a 1LE copy (albeit heavily modded) when I get those 3.91 installed! Honestly, had I known of the 2013 1LE back in 2010, I don't think I could have waited this long to get my car. But enough coulda-woulda-shoulda.
The "competition's" Track Pac (aka Boss 302) doesn't stack up to the Camaro 1LE (even to the SS). The Mustang's main failing is its brakes. I was at the SCCA NW Regional event this year and talked to a competitor running a brand new, trailered Boss 302. He was fast, no doubt about it (he was running new 315R18 Hoosier A6 slicks all around versus my staggered Toyo R888). He admitted that the greatest failing of the Mustang (even the GT500) are its brakes. You get the same puny rear brakes across the board. He said that he can't get one hot lap around a track without completely loosing his brakes.
