I've had megan racing coilovers on 2 of my past cars, and they are excellent build quality. They are in fact made by the same company that produces coilovers for Apex'i, Greddy, ETC. If you want to bash Megan's quality, you might as well bash the other companies.

My only gripe about both sets I've owned, (WRX and AE86) was the valving was not refined. Mostly the fact that the shocks did not have enough rebound dampening and I would get some really nasty high speed bouncing on rough freeways. However, seems the OP likes the handling characteristics of his setup...
