Hey guys,
Need opinions and feedback on tein type flex or tein type basic. I want to drop my car but I want to know what's the difference in these two items besides price and one being compatible with the edfc. Please feel free to pm me and help a fellow g35 coupe driver out. Thank you in advance.

Flex uses very stiff spring rates at 12kg. Basics uses 9kg. Flex are rebound and compression adjustable while Basic does not have any adjustability. Flex has full length and height adjustment for seperate setting of height and spring preload. Since the length and height adjustment is seperate, you can maintain full suspension travel. The Bascis do not have that ability and are only height adjustable.
