Rear motor mount, passenger motor mount,
2 point subframe brace at minimum, decent intercooler, a tune, pulling the spare and maybe even the back seat for drag nights should get high 13 with practice.
I know my car ran 14.6 on the stock re50 wheels and tires with only the spare pulled and the above mods on an absolutely abysmally hot and humid day. Id like to see how it runs in decent weather.
