megan racing has somewhat of a good rep when it comes to inexpensive drifting coilovers. some friends install/have them on their S13s and 14s. i heard they are made in the same factory that apexi-i (non jdm) coilovers are made, so it's got to be at least decent for the price. but it's only hearsay from the various forums i've searched. note that drifters usually break a lot more suspension parts than other enthusiasts. also, they are probably more popular on Z33s because they attract more of a "tuner" crowd than the G35 community. anyway, if anyone else has something more solid than me i'd be interested to hear it for future suspension mods i might make.

 

I know a lot of buddys that use them on S13's, MR2's and RSX's, and so far they are all very pleased with the coilovers, especially at the price.
