does any one have the Tein HR coilovers are their car. If so how do they work as far as a dd. I have sreached and found no info on the HR plenty on the SS and Flex. I have a set of the HR i could use but i don't want to put them to have to take the back off. If they are only going to bance you to death or mess up the ride of the car. Also where is a good setting to have the springs adjusted to.
