So if you were going to start building a project car that you wanted to take to the drags on Friday, do the King of the hill thing at Delaware on Saturday and maybe tryout a few turns at an Autocross event ( And oh yeah use as your daily driver )

Where would you Start?
What do you do first?

Well after the mandatory tune up, I say suspension work beginning with polyurethane bushings and subframe connectors.

 

Yeah Suspension and stiffening of the Chasis seem like the right place to start to me also but what can you do to make radical improvments in the suspension of our cars??

Is there a coil over suspension kit for an F body?

Does anyone make sub frame connectors that are substatial enough to make a difference?

Would a 4 point cage be better than the SFC route?

 

There is a coil-over suspension kit for our cars, but I'll get back to you with the web address. I'm sure you could find it on here.

Spohn subframes kick ***... I've got them and felt a large difference in handling and ride quality after I put them on. I've got my whole suspension done in polygraphite/spohn tubular/ and eibach as well.

a cage along with the subframes would be absolutely awesome to drive.

 

How about a 4 point cage with sfcs?

It's a bit of overkill I guess, then I'd go with 4point over the sfc's. The cage has a better capability for weight transfer.

Haven't seen a coil over kit, but maybe some adjustable shocks and struts, heck a whole adjustable system, panhard rod, torque arm, lca's would really make a good system for adjusting to the conditions.

Add a wonderbar if possible for the delaware, stiffer sway bars, then disconnect for friday track runs.

 

OK you want radical here it is... take out that POS soild rear axel and swap in a vette rear end you wanted radical there you go

 

Definately start with the suspension and chassis first. Then brakes, then the engine.

I fully support the idea of SFC as I believe they are preventative maintanence for the chassis over the long haul...especially if you're gonna add more power. And you can't go wrong with the roll cage either. I think you would be safe to one or the other. Both would be nice though.

For good (but pricey) suspension components you'll probably want to look to the likes of Spohn or Kenny Brown...a-arms, SFC's, pan-hard rod, track arm, etc..

 

Well I dunno about your budget but I would do drivetrain and suspension first.
There is a kit for suspension- http://www.thunderracing.com/index.c...ategoryid=1071
I would do:
t56 swap if you got the extra cash
Spohn or kenny brown SFCs (tubular and come with braces to help out the center as well), and the only ones I would put on a car used for lapping or autocross
global west springs
spohn adj. panhard rod
global west springs
koni adj. shocks/struts
global west torque arm if you got 550 bucks usd
global west steering box brace (wonderbar replica)
4th gen rear or get a eaton 3.73 carrier (assuming your not putting out huge numbers)
front wheel spacers
17-18 inch rims and some stickies
Baer brakes or spohns 1LE package
a combo of polyurethene and aluminum bushings depending on how much street driving you plan on
roll cage

Then I guess all thats left is engine/appearance which is all a matter of taste, use, budget.

And btw the c4 vettes independant rear suspension doesnt help laping times at all, infact some people believe it can hurt them...

if he use slicks and run low 12's on Saturday then he will need to get IFS parts on Sunday..lol

Daz

 

Not if it's a Dana 44.

The coil over kit you guys are thinking of is the Art Morrison kit. I wouldn't autocross with it, that's not what it was designed for. I think Ground Control makes a CO kit that is meant to take some abuse.

 

lol I hope that reply is not for me cause we all know that Dana44's are solid axles.Im too lazy to read the whole thread..lol

I guess I shouldve said IRS instead of IFS..

IRS-Independent Rear Suspension

 

Daz, C4 'Vettes(4+3 and 6 speed cars) and Vipers use Dana 44 center sections. They don't break very often.

 

Thanks for the great respones!!!

The coil over kit from Art Morrison does look a little flimsy even for everyday driving let alone autocross. Thunder racing's coil over kit does not show up on their web page something about this item under construction. Oh well have to keep looking. Anybody that has a link to a good coil over set up please put it up.

I think you guys are right about the SFC's they are a must. And I probably mislead you a bit with the 4 point cage. What I was really thinking about was a roll bar just behind the door opening with a support going back towards the rear frame and another support starting at seat height and going forward to the front frame rail. actually six point conection but not a full cage.

As for the rear end I have come into a 9 bolt with disc brakes I think this will be a good start.

Check out global west bud. They got sh!tloads of stuff made for thirdgens involved in lapping/autocross. I believe they have a few choices for spring rates depending on how much you street drive vs. lap/ax.
If you are really going to go hardcore racing skip eibachs. They are amazing for street use and lowering your car a bit, but you will get a bit too much mush if you have low profile stickies.
greg

 

Checked global west but no deal on the coil over set up.

What does everyone think about going with an old fashioned screw jack on all 4 stock location springs and adjustable struts and shocks?

 

What do you mean no deal?

LOL I think your nuts and looking for busted parts. Stiff springs would get you better times anyway
greg

 

I mean they don't have a listing for a coil over front suspension for a 3rd gen.

And Why would I get busted parts from using screw jacks. NASCAR Guys use them everyday without busting parts?

And obviously if I went this route I would change the spring rates to something more appropriate than stock. I would just keep the springs in thier stock mounting locations and use the screw jacks to adjust ride height and Corner weights when doing the king of the hill thing.

Im sure Ive seen them before... goin to look.
http://www.globalwest.net/camaro93.htm#Springs:%20(1982-99)
Top of the spring list. Front springs 82-92, come in performance street, semi-competition and competition levels. All three levels are $144.50-146.50 for a pair and lower your car 1 inch approx.

As for screw jacks I dunno for sure but the way I see it is if you get shocks with to stiff valving and springs with too stiff a rate on a subframe car your chassis/tires/rims is just going to take the impact and beating. NASCAR courses would be quite smooth compared to most of the places you will see AX tracks set up in ontario. Some road courses have rough spots as well, and if you want to cut a corner you need some bump absorption.
Maybe air bags? Same concept but less aggressive maybe. Just something to look into...
