wassup guys, i had my 08 g37 sport coupe for about 4 months and now i think its time to lower my car, but im having problems deciding between tein basic and tein flex. I was wondering if you guys can help me and tell me wat the difference is between those two cause iono if its worth spending an extra thousand for tein flexes... if you guys can help that would be awesome... thanks!!

 

Quick answer. If ur tracking flex if ur dding basic

 

depends on how much you wanna spend too. theres couple coils out there that are cheaper then tein's and are about the same quality, like the tanabes, bc, and stance!

 

I am going with the Tein SS-P. The SS-P springs are 9k front, 8k rear. The flex is 14k front, 12k rear which is really stiff. If you are looking for track handling and don't care about ride quality then go with the Flex, otherwise, Basic or SS-P. The SS-P adds an upper pillow ball mount for adjustability over the basic but I am not sure if there are any other differences. The only bad part about the SS-P is the fact that they are on back order from the factory due to the problems in Japan. Mine are supposed to ship in about 5 weeks.
