    I think a facelift (from 2015-18) with a SIX speed manual would be cool

    The problem is not the Tuning. It has less friction than any other DCT in game.

    The SBR's has the same friction levels the ETK's has, so I won't bring the ETK here. When I added the SBR's DCT to my Sunburst it improved drastically.

    Also, it behaves on a smooth manner, instead of the agresiveness you'd expect from the Sport S and RS. The ECU's could decrease the DCT clutch time for them and it would be a lot better

    Sunburst 20B RS and 25B RS or "prodrive" I haven't decided yet.

    Sold globally these cars were the fastest, most expensive, and rarest models from the factory with only 1000 being built per year. coming as sedan and wagon in 2.0turbo 268hp or 2.5turbo 292hp versions with adjustable racing struts, carbon fiber hood and trunk lid, light weight glass and rally car body kit. The only option being 5-speed manual or DCT, these cars weighed between 90 and 150lbs less than the RS or RS AERO depending on which engine and transmission had been picked. These car are considered by enthusiasts and collectors to be very desirable and valuable so resale prices are high.

    Built on the nicknamed by hirochi employees "super sunburst" platform like the 20B and 25B these five models were built in very limited numbers and while they were technically completed in the hirochi sunburst main facility in Japan. Some were sent as complete cars to a famous racing engine builder in Britain to have their engines complety reworked while others just had their block and heads shipped to Britain and then shipped back when the work was finished. When completed all cars were rated in PS, their model names reflect that and their production was spread out over the production cycle of this iteration of the sunburst so each year only 20-50 of each model was built.

    348RS type B
    Built to be able to be sold in the USDM and globally the 2.5 L's core engine was reworked by hirochi's partner engine builder and the shipped back to be fitted with hirochi's turbo system and computer to meet regs while offering high performance. Only 500 were built.
    344hp, 5-speed manual, AWD, race struts, high performance brakes.

    304RS type B
    Built to be able to be sold in the USDM and globally the 2.0 L's core engine was reworked by hirochi's partner engine builder and the shipped back to be fitted with hirochi's turbo system and computer to meet regs while offering high performance. Only 500 were built
    300hp, 5-speed manual, AWD, race struts, high performance brakes.
    screenshot_2025-11-22_16-09-04.png

    337RS 20B
    Built to be able to be sold globally the complete cars were shipped to Britain to have their 2.0l engines complety reworked by hirochi's partner engine builder and then they were delivered to their buyers but unfortunately they could no longer pass USDM emissions regs so none were sold there. Only 300 were built.
    333hp, DCT, AWD, race struts, performance brakes.
    screenshot_2025-11-22_16-10-08.png

    385RS 25B
    Built to be able to be sold globally the complete cars were shipped to Britain to have their 2.5l engines complety reworked by hirochi's partner engine builder and then they were delivered to their buyers but unfortunately they could no longer pass USDM emissions regs so none were sold there. Only 300 were built.
    380hp, DCT, AWD, race struts, performance brakes.
    screenshot_2025-11-22_16-12-40.png

    390CFR-R
    Built to be able to be sold globally the complete cars were shipped to Britain to have their 1.6L engines complety reworked by hirochi's partner engine builder. these these engines were so thoroughly reworked that they were street legal racing engines that were only legal because of the collaboration on coming up with a computer that could run them and keep them legal. then they were delivered to their buyers but unfortunately these engines had no hope of passing USDM emissions regs so none were sold there. Only 100 were built.
    385hp, 5-speed manual, AWD, race struts, performance brakes.
