The most typical brands i see bought for the CT are Megan Racing, BC, and Tanabe. I went with Tanabe due to it being made in japan (JDM FTW), the rest are... questionable. BC is like a chinese rip off (s'ok for me to say this cuz i'm chinese lol) and i'm pretty sure megan racing had its roots from ebay selling. They're all around the same price ~900 average. I might get flamed for my bashin' on those 2 brands but, so be it.
I've had 0 issues with my Tanabes. It's a super comfortable ride. I've riding on them since May.
1 physical difference i've noticed is that the Tanabes don't come with top hats for the 2 front struts. However the Megan and BC do. That'll help with installation. No need for spring compression lol
If you want to get extra baller mode, Cusco and TOMS makes a coilovers set for the car lol.
Here are a few pics of my lowered CT, i'm sure you've seen before
(I know it looks a bit sunken but spacers will be installed this week. Wheel specs are 17x7 +38, Work CR Ultimates in matte bronze. I'm lowered like 1.25 inches. I can't go lower due to huge speed bumps at work and i prefer to be a bit more functional than most)
And here are a few extra shots. http://imgur.com/a/laKUj
My finger gap is about 2 fingers for the front and rear.
