The long slippery slope of track mods - lets start with the suspension

[j.fro]

Hmmm...I've got some suggestions, but they'll alter the course a bit:
1) R-comp tires or an extra set of wheels with R-comps. The BEST mod you can do.
2) Adjustable drop links are only beneficial when you've already got adjustable sway bars. The drop links allow you to set the sways without preload when the car is level.
3) If you are looking to keep your stock road comfort, get stiffer sway bars and the drop links...But, if you are more interested in overall track handling, get a set of adjustable coilovers. I've got the K-Sports, and they have enough adjustability for both daily driving (rougher than stock, but tolerable) and competitive autocross. As a bonus, the K-Sports come with camber plates (and don't need adjustable toe links!!!), and they can be had for around $1200.
4) Depending on the track, some track brake pads may be a "must have" item
5) stainless steel brake lines and a flush with ATE Blue
6) 4 or 5 point racing harness or at least one of those seat belt locks
