The reason i like mugen is that it never has any unwanted options such as the other brands. if it really has options, mugen has thought inside out its feasibility. and i think whatever mugen chose to build, it already qualified the supplier, there should be problem free. unlike i owned a 960 as a 2nd car, its options were quite lousy, and expensive.
for mugen, it is just a racer out of the box. it will never build a car which must require option to be able to run
