Default Professional Suspension advice needed for Build

Before you take the time to read my indepth essay about all my suspension questions, Please do not post and stupid stuff. I need some suspension Experts, people that know what their talkingabout and have experience. Im loolking for some real input from a real road racer, and all useful advice, input, pointers etc.. is Greatly Appreciated. Thanks in advance.



I am currently building a ek coupe specifically for road racing, I want to compete in Timeattack in the Street class. Then making my way up accordingly and doing all adjustments & mods needed to stay competitve. I plan on taking my time with this build and no corners will be cut nothing overlooked. I am working with a trusted local builder/tuner on this project. Ill give you a little info about the build


----|||| you can skip this part and go down if you dont want to read ||||----
This paragraph might be considereing "off topic", but to me for some of my suspension questions it is rellivent, so I dont get bombarded with questions on what im try to do.

^^^ ^^ ^^^^^^^^^^^^
I have a 96 coupe w. 00 front end, all Vergin no accidents, no rust, no body damage. I am ordering parts as I need them throughout the build rather then buying a bunch of stuff all at once. It is getting a 6pt cage welded in as we speak, and I have started buying a few small things. Once the cage is in its getting prepped and going to paint, inside and out. I am going to do the k24 frank. swap. Ill buy whatever I can find a deal on but I want to buy a k20z3 (comes LSD save money wer u can) full swap & buy a K24 block preferably not bare. I want to do it this way because me and my tuner both agree its good to have everything you need and extra parts. It will be bored out to 2.5 some Interal work but nothing overboard, knifedged crank, possibly a s2k crank. So it will be fairly built, Springs, Retainers, Valve, Rods, 13:5 -13:7 somewere around there; pistons, new bearings, Some nasty lift Cams, Then all the fun bolt ons to support, Will not Run ITBS.

My goal is 320whp on my mustang without pushing the motor to the limits. gotta dream high
me and my tuner have all the engine stuff squaired away and he builds Tons of fast all motor KS, but Everything else I have some questions on.

So I have a general Idea of what I want too do. And Any inteligent Input, Ideas will be appreciated. And I have to run Dot approved tires, keep that in mind.

-Coilovers:
I cant fork out enough to get some motons, ohlins or anything else in that price range. I want to find a middle ground, Something not over $3000 (and im not saying i want to spend 3k at all) but can meet the needs of a dedicated track car. I want some kind of monotube, something thats proven, Reliablity is #1, And I need to be able to get parts easiy for rebuilds. Im pretty sure I will have to get custom springs made (suggestions), me and my tuner agreed that to Start off were gona try 22kg (front) and 14kg (rear), going really stiff up front because the k24 is not exactly light.

So I need some good suggestions on what i should do? Remember Its not gona be driven on public roadways, so comfortability is my last concern.

Here are a few things Ive been looking into...
-KW V3: Always a viable option
-Jic FLTTAR: My tuner said a lot of his customers loved them
-Tein SRC's: kinda on pricey side, Bad Quality cheap parts??? so ive heard
-PIC Selects: If I have to end up getting something more affordable this is my #1 choice
-Zeal Super Functions: im thinking one of my best options
-Zeal Function-X:

Springs... 22 F & 14 R
-Will need to get custom made? and what companies are good at this? all i know is swift's top notch.

Sway Bars...
- Was planning on just running TypeR? or is it worth it for me to buy Big sway's I was afraid that bigger sway bars mixed with high spring rates would be a bit much.
- Function7 Endlinks: cheaper then ASR and look about the same too me

- Function7 LCA's (already have)
- Function7 Subframe Brace (already have)
- Beaks Tie bar
- Skunk2 Front camber kit (already have)
- Skunk2 Rear camber why not keep it the same? hah

- Js Racing Roll Center Adjuster, I kind of understand what it does, kind of makes sense, But I want some assurance. Is it worth buying? Need Input

Bushings:
- Rear Trailing arm bushing: some kind of spherical bushing... I need some good options
- Master Bushing kit: I wanted to get polyurethane but I really like the PIC Performance hardened rubber bushings
- Steering rack Bushings: Worth getting? what kind?
- Shifter bushings: "" ""


Chassis reinforcement:
- 6pt Weldin cage (in the works)
- 4pt rear strut bar PW JDM (already have)
- 3pt front strut bar
- Flat bottom, aluminum from front bumper all the way to back of wheel well


Im sure I might have left out some things but, Ive been writing this for almost an hour now xD . So to everyone that took the time to read through all of that I really appricate it and Im looking for advice on anything suspension related. Let me know I want some real advice from somebody experienced and knows what their doing.

So thanks for your time & ill end this long thread with a little treat. Well nothing too special but i cant wait too see it in a couple months ;D.

How I got the car everything stock, except those enormous rims.


I do have sideskirts and moldings now ^^ heh


shocker on the rear of course..
