I LOVE THEM.... they truelly change the handling of the car. I was considering the JIC, but the difference in price at the time and my history with Tein products lead me to them.
I love mine. the tein springs would be way too soft for the MSP. depending on what you plan to do with the car though (but why buy a sports oriented car if you want a softer ride?? *shrug*). i also wanted to try using the tein camber plates for the FC RX-7 to see if they'd fit but never got around to ordering me a set and seeing how they fit and perform.
