track/autox suspension setup...
setting up a track fd over the winter and now i am pretty confused on a suspension setup. this will be my first season so i want something that will be slightly inexpensive but still handle well. i was originally looking into coilovers but after searching and reading some of howard colemans post i think i may go with a shock/spring setup. i am thinking of either bilsteins or koni yellows, and tien s tech springs ( f rate 426 r rate 324 ). i know most track cars run close to 500 front and 450 rear spring rates. also looking possibly at the ground control coilovers. as for tires i am planning on running nitto nt-01's based on the price and they are well compared to the ra-1's. also i was reading that removing the rear sway bar may be better in track events. but needed for autox to slightly oversteer more. any imput on what i should do is greatly appreciated.

My suggestion:
* Koni shocks
* Ground Control coilovers (you can later get a few springs to adjust for various events) Tein S-Tech springs are a good starting point if you don't want to shell out the extra cash for the GC's just yet.
* Widefoot Billet Swaybar mounts
As far as swaybars, I would leave them stock for now. As you get more seat time, the Tri-point adjustable sway bars would be a good upgrade.
Nitto NT-01 is a good tire. If they have your sizes, that's a good pick.

Sorry for the hijack, but could someone point me in the direction of why to use the spring/strut setup over a full coilover? I just really don't understand the benefit. Thanks,

It's cheaper, you have more control over the spring rates, and you can usually get better dampers that you don't get in a full coilover setup. This is assuming you are using the "JDM YO" coilovers. For instance, I'd rather run Bilsteins with some springs rather than JIC coilovers.

Because softer springs increase grip, you'll need to find a compromise between ride-height and stiffness. The springs need to be stiff enough to keep the car from bottoming too often. Any stiffer is too much or should be used to lower your ride height.
But you're building a lapping-day car, not a racing car, right? Start with proven, conservative pieces. Use springs around 400-500F/300-400R, and set corner weights with ride height around 25.5". Once you get familiar with that setup and know how you'd like to change the handling, people will be able to suggest particular parts to get there.
Final point: on a limited budget, a stock suspension will get you farther than a stock radiator, brake pads or swaybar mounts. Spend wisely.

Wait until you can out-drive the suspension before upgrading. Too many people try to get a top of the line setup before their driving skills are at the same level. While it sounds like a good idea to have something to "grow into", it can actually be a bad thing. The closer you put the car to that edge, the less feedback you get from the car to let you know how close to that edge you are getting.
