Everything's different; they're totally different kits.
Erebuni itself has two seperate kits for the MX-6. The 711(shogun) and the 44. Search for information on the two. The TC is similar to Erebuni's Shogun kit, but is not the same. The Erebuni Shogun has a larger mouth in the front bumper and sits lower to the ground. The Shogun's sideskirts come up higher on the car's body behind the doors. The rear skirts look very much alike, but are probably somewhat lower on the Shogun to keep everything consistent.
You need to search; you'll find pictures and those are your best shot at understanding the differences.
