^^ Absolutely not, at least not from being linear alone. If the rates are way too high then it doesn't matter if it's linear or progressive.

Should I worry that RCE's will create more understeer? To a fault perhaps?

In a steady state corner the stock setup is fine, the front end lets go a little before the back making for a 'safe' setup. But have you hit the front bump stops yet? I have a few reducing radius turns on my way to work that I like playing with. Even on OEM tires I have to slow down so I don't run into the damn bump stops and have the back end of my car start racing with the front end.

I like a car that's predictable and controllable at the edge. I honestly can't believe the FRS was release the way it is.

Not at all. Springs are just part of the equasion. Get a good alignment with some actual negative camber and the car will be wonderfully neutral. RCE's starter kit is great for getting a real alignment.

I've got a set of Yellows ready to install as soon as the weather gets a little warmer. I have some camber bolts as well.. should be a good start.

With the starter kit I'm at -2 degrees front camber and -0.8 degrees rear. The car may want more in the rear, but that's where I'm at for now. On the street it's very neutral. The rear will stick when I want or start following the front if I let it. The front is just perfect with godly amounts of grip.

I've had to wait 7 months to get this to an AutoX. Hopefully it'll be warm enough on the 30th to get a good test. I'm very confident.

I have a set of these RCE springs in the garage. My car is pretty tail happy even with a alignment. Hoping these settle the back end down a bit. Worried the rebound is going to get even worse though.

What do you have installed for camber correction? What is your alignment?

From what I hear, a bit of toe in the rear (1/16") really settles the back end down. I go for my alignment next week and that's what I'm going to get.

Do you have crash bolts up front? Which ones?

Very useful thread, thanks all. I met 1 fellow FR-S owner, sw20kosh (i think???) at Thunderhill, and from what I recall he posted a 2:12 on RCE Yellows with 245 or 255 width tires, very impressed.

Anyone knows if any vendor sells the RCE Yellows as a "kit", i.e., springs, camber correction bolts/perches, etc, etc?
