The CS-R3 also benefits from a sequential shift six-speed transmission and a limited-slip rear differential, together with a weight-optimised safety cage, designed to FIA requirements. TMG has sourced tailor-made wiring looms and motorsport engine ECUs, and market-leading Tarmac and gravel suspension kits have been developed. The CS-R3 has been tested on different surfaces in readiness for Rallye Deutschland, which will cover 170 miles over 18 stages from 21 to 24 August. The first customer cars will be available in kit form during the first quarter of 2015, with prices expected to be comparable with other R3 cars. Prices will be announced following confirmation of final specifications. Nico Ehlert, TMG Principal Engineer – Customer Motorsport, said: "It's important to say that the GT86 CS-R3 which Isolde will drive is not the finished article; we need the data from Rallye Deutschland to finalise our development programme.
