Are tein's rebuildable and is it worth it?`

I have tein cs coilovers on my ucf10 and to be honest with you, they ride like shit. They came with the car and the previous owner rode with them almost all the way down. Even after raising the coilovers they don't ride any better. I have almost a finger gap if not a little less and the coilovers still bottom out. So is it worth it to rebuild the tein cs coilovers or just say, buy a set of megans or something. I really don't like how the tein cs coilovers don't have perch height adjustment.

Yes, they're rebuildable, but no they're not worth it based on what I've heard about their customer service and turn around time. Go for the Megans.

Never had a problem with tein and I have rebuilt twice. You can have te cs rebuilt with shorter stiffer springs with more aggressive damping
