When Ra25 was manufacturing all mechanical parts on it was depended on Formula Student cars, which were very reliable but excessive in most of the cases since the solar car cannot reach high speeds like formula student cars or needs to aggressive like a formula student car.
One of the important parts on a solar car is the rims. This time Near East University Solar Racing Team designed their own rims which are closed in the middle for better aerodynamical drag. Front and rear arms, suspension brackets are specially designed for Ra27 and tested for various cases just before manufacturing. Ra27 has its steering, brakes and some of main components are taken from an atv quad cycle which is around the same weight as Ra27.
