LCAs can be swapped in under an hour, really easy.
Panhard rod can be very difficult, it really depends on your comfort with drilling into the frame and having to retionalize around problems when instructions dont go quite right. I did mine by myself with jack stands and hand tools... took an entire day... but i can prolly do it now in about 2-3 hours. so far i have installed everything in my sig with just hand tools, floorjacks/jackstands, and by my self.... one thing i have learned is that dificulty is relative to the installer.
