Bold claim, but I think I'm most of the way there, in terms of design. To be fair, none of this is my own doing; I'm building on the work of others, and just documenting it as I go. Here's a stream-of-consciousness version of what I have so far, in no particular order.
First up: wheels and tires. That's been taken care of already: 17x9+27 wheels with plenty of caliper clearance (mmm, 14" rotors, if I want them), and Falken Azenis RT-615 255/40/17s. Not the best tire you can buy, but best I'd ever consider driving on the street and taking to an autocross or HPDE. This piece comes in around $1400.
Next, sway bars. I went with the RMDSM front and rear bars, which ought to balance the car fairly well. These came with a nice set of poly mounts. New, this was a $300 set, but I got a deal on a set of used bars. In the front, I've created a pair of adjustable end-links; if they work out well, I'll probably do something similar in the rear. (There's really no magic there; a couple of rod-ends and a threaded rod from McMaster-Carr, and some simple rubber boots to protect the spherical bearings in the rod ends.)
Third, alignment adjustment. Up front, the SPC replacement upper control arms with camber and caster adjustment via the adjustable ball joint and eccentric anchor bolts. In the rear, some simple spacer washers and longer bolts for the upper rear control arm ought to the trick. I'll probably be spending just shy of $500 on this.
Okay, that's the easy and obvious stuff out of the way. Next up: shocks, springs, and their associated mounting hardware. For shocks, it's hard to beat Koni Sports ("Yellows"), so I'll be using the 8041-1207 up front, and 8041-1208 in the rear, with .062" snap-ring grooves cut into them about five inches down from the top of the shock body. Those grooves are for the Koni 1038.41.04.20 80-series circlip on which the Koni 80.0000.1 42mm-ID kit will be installed (25mm upper spring perch, lower perch with locking set screw, and threaded sleeve). Mounted on the perches will be a pair of Hypercoil 8" springs (rates to-be-determined, but I'm leaning toward 600/300, since that's what Dennis Grant settled on after doing quite a bit of testing with this particular setup), supported by a pair of Hypercoil zero-rate helper springs and a Torrington (nee Timkin?) thrust needle roller bearing (NTA-3648, with the TRA-3648 race) to keep the springs in place and make adjustment a simple affair. Above the upper perch go an upper bearing plate and spacers from RRE. Finishing the whole thing off, a Koni 72.34.48.000.0 25mm linear soft bumpstop. So far, this piece of the puzzle looks like it'll run just shy of about $2000.
After that, there's a few other bits and pieces that can be addressed; any rubber bushings can be replaced with poly or spherical bearings where appropriate, and a little time on the alignment rack would probably be worthwhile. :-)
I think that's the major pieces of what I'm looking at doing (eventually). So, for the low-low price of just under $4000, you'll have a 2g DSM that handles like it should have from the factory. ;-) I believe I mentioned once before that I have a history of going overkill on things like this, didn't I?
