I've had some confirmations on EF springs being interchangeable with DA's. But are the shocks also interchangeable? I have a ef shell im selling and i had bought tein s.techs and tokico blues for it and never put them on... the option of putting them came up ina conversation and now i want to know if i can do it without having any problems cuz if i can... YESS I WONT HAVE TO SPEND THE MONEY AGAIN!!! thanks
