When I got mine they were 10F 8R, and I was running over 400rwhp through 255 R compound tyres. Had I kept the car I was going to try a custom 8F 6R setup on them to see if it was any better. The US market ones must be hugely different.

Just felt I had to post as there seem to be loads of threads saying x are rubbish, the springs and dampers are mismatched, get Teins instead, they are great. When in my experience they are anything but.

 

Yea, one thing I've noticed is that they tend to use front springs that aren't stiff enough, or alternately, rear springs that are too stiff, but that's not hard to fix. But otherwise in my experiance and reading they're excellent.

 

Don't most companies use different valving for US spec coils? Since we have horrible roads here. I've only had flex's on a civic hb, and they were EH, but I bet they're pretty nice on the FD. We'll see....About the megans, I've driven a S13 turbo hatch with them, and I liked them. They were smooth, and turn in was very predictable. That could be tires speaking though. My wife also drove the car, and even had a little exit drift on one of the turns she was taking. Not bad, and extremely cheap. Like many have said, they're better than 13+ year old set ups.

 

i have the megan racing track version for my fc and the springrates are 14k in the front and 12 in the rear, pretty fun.

 

HOLY CRAP! That's literally twice as stiff as mine, and much, much stiffer than any spring rates I've heard of being used on full on race cars with huge wide slicks. That's just marketing to those who incorrectly beleive that stiffer is better.

In fact you want it to be as soft as you can without it negatively affecting the dynamic alignment too much. Modern race cars are so stiff only because of aero, where small changes in the attitude of the car make big differences to the drag and downforce.

I've attached a picture of me going full out in a corner at the track on 225 R's and there's practically no body roll, so that shows that it's already plenty stiff to keep the car flat in the corners. No need to be twice as stiff, that's for sure.
