I'm running 245/40R17 Direzza DIIs. Here's the alignment settings I'll be using:

Damper settings, clicks from full stiff (from the RCE Facebook page):
Front Rebound: 10 clicks
Front Bump: 10-11 clicks
Rear Rebound: 13 clicks
Rear Bumpf=: 7-8 clicks

Camber (recommended by Mike):
Front -3.3
Rear -2.1

Thanks!

We can preset the ride height out of the box for you to Myles' final setting. I think we were right around -1.4 inches or so, but he was playing with rake a little and I'm not sure exactly where he ended up front and rear. He has a ton of notes...

Damper and camber sounds good!

So my idea is to buy coil overs to push them out a little and also be able to add a little negative camber. I will be going to at least one track event this summer and maybe a autox here and there. I have been looking at the KW v3s but I'm not sure i need something that crazy and adjustable but i do want something i can DD and Track.

KW V1 or RCE T0. Better handling with the RCE T0 but slightly nicer ride with KW V1. Both great.

The speed by design coilovers sound interesting, but from the dynos and their own admission they're not really a performance coilover.

I do go to the drag strip since it's cheap.

I already tried the GC coilover kit, but it just bottomed out the shocks with 5/8" drop on 440lb springs.

See above post.

Bilstein coilovers may be an option for you too if they fit your tires.

I'm on stockers, won't upgrade the tires till I can afford a nice set of wheels, to put some Ventus V12 or Nitto Invos on.

I was looking at the Bilstein B14, but since it doesn't have a threaded body to keep as much shock travel available, I fear it might ride the bumpstops if I drop it 1.5"

I was looking at the Function/Form, since there's a local distributor that can repair them if anything happened or the new set from Speed by design, but the latter is new and I don't know if they're good or not.

So I should save my money and not even Consider the v3s? With the V1 and t0 I have no adjustment correct? So I drive from the road to the track and just go?

RCE T0 or Tein Street Flex are good candidates.

I will say that a firm spring rate requires excellent valving in order to have a good ride, whereas lower spring rates and only adequate valving will still be okay.

Intended application is important when picking a coilover. There are "street" coilovers, hardcore track coilovers, and some that are a mix of both...road & track Ohlins for example.

Most good coilovers, regardless of how they started, can be revalved or custom sprung to suit any application. But that may just be a waste of money and you'd be better off starting with something else.

Spring rates usually are an indicator of a coilovers intended application, but not always. Most good ones are customizable anyway.

I love this post.

Awesome!

Getting some info from Myles on ride heights (it's a madhouse here today).

I wrote a set-up guide a while ago but it looks like we never uploaded it. It's a rough guide, you're probably a little farther ahead already/

The Bilstein coilovers are designed for lowered ride heights....they're already shortened. 1.5 inches shouldn't be much trouble. Adjustable lower mounts is not a requirement for me.

I don't know much about Function/Form coilovers.

Only ride height adjustment with V1 and T0. It makes things easy if you don't want to fiddle with things.

V3s are flexible and a good quality coilover...you would gain a few things with careful adjustment but it's just a question of whether that extra tuning potential is worth it to you.

Looks like he settled on 35mm.

I went with the V3's now. Hoping to improve my ride quality as I'm lower, but not slammed. The ability to adjust damping for group driving events and tracking is awesome. Can't wait to put them on and learn how to adjust them.

I wish I would of known that when I ordered my T2's, would of saved me loads of time/money.

so last couple days ive been considering the wrx 4 pots. ive read just about every thread on them but im still undecided. id like braking performance to be a little better then the stocks are with some nice pads. these should give a slightly stronger bite right? do you know the oem frs piston size off hand?
