Looks like MRT will be the exclusive dealer in the Cosworth kits.
Middleton told motoring.com.au that local pricing "varies with exchange rate and we are currently finalising pricing".
The packages add a small number of new parts to the 86/BRZ, the basic stage 1.1 package comprising a polished stainless-steel cat-back sports exhaust system, high-flow air filter and an ECU tweak that hikes power by 17 kilowatts to 164kW.
Cosworth says the packages were developed "using the same methods employed in Formula One and sports car racing" and has crafted the entire range of upgrades packs to be forwards compatible. The idea of a staged approach gives customers an "affordable path to upgrade their vehicles" according to Cosworth.
Stage 1.2 adds an 'overpipe' or front exhaust with a spherical resonator and matching ECU tweaks to boost power to 167kW, while stage 1.3 adds a tubular exhaust manifold with thermal ceramic coating and further ECU calibrations to reach 171kW.
