Inden-Design has some experience tuning Daihatsu cars, and have included the Materia in their latest project called the ICECUBE. The modified Daihatsu features a body kit, new paint, wheels, sport exhaust system, and interior upgrades. The Materia received VIP paint in matte white, which gives the car a unique look and led the tuners to name it the ICECUBE. For the aftermarket body kit, Inden-Design left the stock front bumper, but added daytime running lights, triangular mirrors, door handles, and a carbon fiber boot lid cover to improve the aerodynamics. Also included in the kit are BBS wheels measuring 18×8.5 and 18×9.5 in the rear, with 215/35/R18 and 225/35/R18 high performance tires.
