I always go to the Tarett website when I am trying to see what suspension parts like these are interchangeable.
Porsche Rear Toe Control Arm Link, 996, 997, 986 & 987
This shows that the toe links for 986/987/996/997 are the same.
Are the Megan toe links priced per pair? If so that seems like a great price.
For the tie rod ends do you mean should you get ones that are adjustable for bumpsteer, like these?
Toe Control Arm (ea), Motorsport Style
I have the rennline version with bumpsteer but that is only because I got a good deal on them secondhand, I have never adjusted the bumpsteer. It is quite a bit more expensive, I would have to let someone else say whether they think you could get a good benefit out of that.

I can share my settings
Front: -2.5 camber, zero toe. I think you can achieve this with lowering and slotting and won't need GT3 LCA (which I do happen to have, I am at stock height still though with no lowering). You could probably get close to -2 without slotting with just the lowering.
Rear: -1.9 (that is maxed out for me, I was shooting for a -.5 spread between front and back. With lowering you should easily be able to get -2 if desired). Toe, .08 degree of toe in per side, for a total of .16 toe in.
I drive to/from the track, little bit of street driving, and have been getting good wear with this setup. To contrast, before this I was at -2.0 front and -1.6 back and was wearing the outer edges more and not getting as even of tire wear. So far I am pretty even with the new setup.
Right now my track tires look like they are wearing on the inner edge more than the outer edge, but I think that is because they are loaded up with clag and rubber that is filling the little holes that show me the tread (Maxxis RC-1). My most recent event is the first one where I changed tired before driving home, and I think the drive home scrubs all that track rubber away. I'm going to mount them up and go for a little drive around town and see if it cleans them off.

I have the technobrace - I got it early enough in my driver development that I couldn't tell a difference... but from various threads I have read on here (the one about the DIY brace) convinced me it was worthwhile. Also now when I take off the sheet metal brace, the bar holds everything rigid so I don't have to fiddle to get the plate back on...
I'm curious to see what everyone else thinks.
