wanting to race a 73 on the track but dont know which springs/shocks and suspension upgrades to do and which brands to go with.

will koni CLASSIC shocks front/back do the trick or no
what springs to go with?
what are and are they worth it to put on:
traction bars
subframe connectors
ant roll bar
what kind of roll cage 2 point? 8 point?
should i get new leaf springs? or just re arc them
thicker sway bars, will one on the back and front be too much

im really new to suspension.
all i know is that i need to change the shocks and springs most importantly and they need to be a much stiffer springs rate than stock.
if i do get all this suspension done, should i have lowered the car before or after

 

Yes, you'll need probably everything on your list if you get serious. And you'll need to lower the car to get less body roll cornering, but that would be part of the spring upgrades front and rear. Most people purchase springs all around that will lower the car 2", and stay with a stiffer rate spring all around when they do. Brand and model of shock depend on whether it's race only, or more of an autocross car that sees dual use.
You'll definitely need subframe connectors, as you'll be thrashing hard on the body, and it will twist without them. Traction bars will be a necessity, but not slapper bars. Get a pair of Cal Tracs; they're the best you can buy.
You'll not only need swaybars front and rear, but also heavier than stock swaybars. And make sure you get both as a matched set.
A rollcage will help stiffen the chassis, and in some events it will be a requirement. But don't choose a rollcage based on just a recommendation; choose it based on the rules of whatever governing agency you plan to run. If you install a cage and it doesn't pass tech, it will be a spendy lesson. Better to make sure whatever you put in meets tech requirements for the racing you plan to do.

 

So first thing i should do is get springs that will lower the car about 2 inches.
then get shocks, single adjustable, double? sooo confusing!
then sway bars, sub connectors etc.
what about wheels, shouldn't that be the first thing i do to see how much tire i can fit in the stock fenders then lower it accordingly?
and what is a anti roll bar that i have heard of

i will be tracking this car every weekend in the summer, but i dont care if its the roughest ride when driving on the street.

 

An anti roll bar is another name for a swaybar; nothing different.
No, you should not purchase tires until you get your suspension done and ride height set. Only then can you determine what will fit and clear. It would be sad to spend big money on tires and wheels to fit it in stock height, and then find out after lowering that they no longer fit.
There's way too many shock choices to say one is THE shock to get. I think you need to do some reading at either autocross sites, or mags that cover the sport, before making a purchase. I would also attend some events and talk to those with experience about what's best, and what this venture might cost to be competitive.
Here's a site you might find interesting. It links to many other sites with lots of info:

Get a hold of Keith here. He races second gens and sells what he uses as well as designs most of his own parts. You have completely skipped the fact you will need brakes just as much as suspension. Keith is a dealer for Gen II which is what my car is packed with. I have most everything done just need to paint and put an engine in.

 

ya i have talked to keith, he told me springs and shocks are a must (obv) but ya i was going to get bigger rotors in the front and see if that would be okay if not i will change the drums to discs.

im going to check your build out right now, are you going to be road racing it?
im contemplating getting his gt springs or going with a more reputable brand like hotchicks

 

thanks man appreciate tall the advice and answers

 

Hotchkis just pays more for advertising. Keith's springs are built by Landrum. I wouldnt ever go as far as calling them more reputable either. Their "Handle Bars" are direct rip offs of Gen II. Really they are both dirived from Herb Adams Trans Am race cars of the 70's and 80's. But as soon a Dave put out his bars Hotchkiss was sure to follow with their own. Dave is the guy who owns Gen II. He has extensive racing with second gens too. This is the ONLY body these guys deal with. I will give Hotchkis this, their product is on Mary Pozzi's car.

 

ya mary's car is craaazy!

i also gotta figure out what the biggest tires i can fit in to the stock fenders wells

 

275's on a 9" all the way around is optimal for racing. I have 245's on a 8" with 4.75" BS and 315's on back on an 11" wheel with 5.75" BS. Keith and Mary both have 9's all the way around but I dont know the BS. Keiths are 17's and Mary is on 18's.
