Ok, I'm new to the forum and barely new to the sentra scene. I've owned a 91 Sentra SE-R for two years and its my first car. It's been good to me despite the fifth gear popout and the endless exhaust leak problem I've been having. Anyway, here's my deal. I'm not very knowledgable about cars but I'm learning, I've done most of the work to it myself minus the transmission and brakes, but I have installed a header, exhaust, and a coilover system from tokico to get some hands on experience. Once I installed the coilovers on my car it has been extremely stiff. My guess would have been when I torqued to retaining nut on the top of the strut that compresses the spring and whatnot I torqued it too much or maybe too little? Is there a specificaion I need to torque that nut too? Like I said I really dont know what I'm doing but doing it anyway so that I can learn from it so please bear with my ignorance. Thanks alot.
