i have never talked to anyone (elise/exige) with different tire types front/rear that were happy with the handling - do yourself a favour, and have them send you the "right" tires. otherwise you may be chasing mysterious handling issues.
"I really started paying attention to cars was when they came out with the Nissan Z, the first body. Then I seen the Cherokees, the old square ones, and I was like, “Wow, that’s cool.” Then I seen the Isuzu jeeps and I seen the Wranglers."
