I haven't used these, nor really inspected the contents, but I did run across them sold as complete package options.
Leading evidence: 'Inspect contents' (no explicit attributable resolution; this is a reported action or suggestion).

I replaced the front coffin arms with �ro ones and the control arm links with EPS polyurethane ones.

I decided to do the same in the rear, and I replaced the upper rear control arms with standard ones.

Suggestion
The FCP kit is reasonable and if you keep your car long enough, you can replace the components you wear out for shipping costs.

My car felt pretty good before I started replacing my control arms.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

there was a vendor that was selling a complete suspension refresh kit, so you didn't have to order the parts separately - control arms, bushings, etc
anybody know what vendor that was?
does it even make sense to order them that way or are you better off picking separate pieces individually?
my thinking is a complete kit would be better because i'm sure i would forget something and be another week or 2 with the car on jack stands waiting for the part i forgot to order
is there a complete list of needed parts if i go the separate parts route?
thanks
I would source separately if it is cheaper.
4 coffin arms, 4 control arm links, 4 upper rear control arms, 2 toe arms, 4 sway bar bushings, Feal coilovers.
That would replace everything. (you might also consider inner and outer tie rod ends)
I'm very happy with how my car handles now.
It's not the lowest, but that's by choice.
Did you go with GT3/adjustable camber coffin arms? I'm getting ready to do what you did, but still waffling on adjustable camber or not.
I'm hoping to keep it at stock height (non ROW) with the Feals.
I have adjustable control arms that I‘ll be installing soon.
At the moment I have non adjustable.
I’m going to install them when I’m ready to get it aligned and have them set them for street driving.
Then I can increase camber for the track by adding spacers, and go back to stock afterwards.

I haven't used these, nor really inspected the contents, but I did run across them sold as complete package options.
They seem really expensive to me.
The FCP kit is reasonable and if you keep your car long enough, you can replace the components you wear out for shipping costs. A little shopping around at the usual stores will get you everything for 10+% less, however. Meyle, TRW and OE mix.
jobyt - If you stay US ride height, you do not need the adjustable control arms. The stock suspension will have enough negative camber. The Feals will dial in nicely. If you want to adjust out some understeer, try an adjustable rear sway...cheaper and easier to fiddle with than front camber. I just bought some new GT3 coffins with Tarett OE-type ends and DemonSpeed shims for $870, so adjustables aren’t cheap. But you can get an Eibach adjustable rear sway for $250 or less. Something to ponder.
My car feels pretty good with Feal 441 and new rear GT3 LCA, but I'm considering replacing all the other arms. There's nothing "wrong" with my car now, but I want to see if I can freshen up the ride. I would go polyurethane, but I have them on another car's upgraded sway bar and the squeaking during the winter annoys me. Can you give a little more input on the before and after feel of your car? Was the suspension shot before you fixed it? How much better is it now?
My car felt pretty good before I started replacing my control arms.
I had a squeaky coffin arm and when I went to replace it I found the control arm links were loosy-goosy.
I replaced the front coffin arms with �ro ones and the control arm links with EPS polyurethane ones.
I was
extremely
happy with how my car felt afterwards.
I decided to do the same in the rear, and I replaced the upper rear control arms with standard ones.
It feels great now.
I now have a set of mono ball rear upper control arms to install when I install my 997 GT3 lower control arms in the front.
Thanks for the detail. Could you describe a little bit more with the difference in feel before and after? By EPS control arm links, do you mean the "tuning forks"?
Yes, the control arm links are also called tuning forks by some.
The steering feel is MUCH tighter.
I can't say exactly what is the best cause for the feel as I've done a lot to the car, but...
I think the EPS "tuning forks" help a lot.
Also the smaller MOMO Prototipo steering wheel helps.
New "coffin arms" helped too.
The Feal coil overs allow for "tuning" the rebound to my liking.
I'm really happy with the steering feel.
Now I just want to add some adjustability for the track and I want to improve the brake some.(Even though I'm pretty happy with my current setup)
I'll be installing bigger brakes(350mm rotors in front) this week and will post about them soon.
Thanks. That�s exactly the type of feedback I was looking for. I�ve read mixed things about the EPS tuning forks with relation to snapping, but it appears you are satisfied enough with them.
I don�t really have a specific size in mind.
I�ll have to install them first and do some experimenting.
I currently have 1mm, 3mm, and 7mm shims, but may pick up some more to play with.
I have manual alignment gauges(toe/caster/camber) so once I have my car aligned I can measure the differences I make by adding shims.
The rule of thumb for front spacing is 10mm to set -1.0 deg camber (GT3 front spec for street). Isn’t -2.5 deg overkill for predominately street use, on street shoes?
Not for me. I have about 2.5* all the way around. Its great in the corners and stable at 135mph. Im not sure if my full areo helps the high speed side of the equation.
