Which coils are better? They're for a 08 coupe.

 

Most of the coils under $1k are quite similar, some don't have damping adjustments.
I love my Megans but I've got a sedan, I believe the part# is the same for trhe coupe & sedan though. The only drawback IME for the Megans is the rear starts out pretty low. This is fine w/ me since I want it low but for those that may want to bring it back to stock height on occasion (or out of neccessity) it would be a problem. I've got my rears set at almost the highest setting and the bottom of the rear fender lip is at 26 1/4" (almost a 2" drop), I could go about 1/2" higher but that's it. The fronts have plentry of range, from higher than stock all the way to super slammed. The damping adjustment is great, you can go from Cadillac Seville "mushy", all the way up to jaw-rattling firm. I've got mine set about 1/3rd from the softest setting, perfect for daily driving.

 

Powertrix coilovers are pretty awesome.
