DJ,

I'd call what we have a trailing arm suspension. I guess you could call a 3-link that as well.



Ack... Moving your panhard bar up and down is not really a way to tune suspension. You should almost always have your PH bar as close to axel center as possible. It should also be as long as possible. Adjusting the mounting point of your suspension links is how you change instant center, antisquat, antidive. You should be using spring rates and antiroll bars to compensate for antiroll.




Pharmd,

Do yourself a favor, go pick up Suspension Engineering by Herb Adams. He goes in to the different basic suspension setups, how they work, also goes through spring rates ect..

Another great thing in my collection is Dave Morgans DVD about building Drag car chasis. Given it's not geared for turning corners, but there are still some basics that he covers that really compound what Herb Adams Talks about. He also goes in to some things Herb doesn't that I feel are very inportant for suspension tuning. Such as shock/spring placement and the affects of leverage ratio.

not sure what the wheelbase is on your truck or this, but i see alot of people grafting there bodys to the corvettes and ssr's on some forums to different vehicles.

That works. Dunno if its just me, but those suspensions are designed for those vehicles. Building up something for a c10 I'd wanna atleast design it around the c10's weight and height of the body and not alter something to fit a c10 application as drastically as changing a frame and all of the stuff that goes along w/ grafting a c10's body onto one.

Has anyone at all, done a similar set up that I might be able to check out, or reference. Who or what shop(s) would you guys recommend talking to to maybe get a little assistance on a project like this. Remember, I am a pharmacy owner, and I am kinda co-in-charge of 5 stores, so time is in short supply around here.

Pharmd,

You might also want to try PM'ing "Legend56BC" Here is a quick post from him. Looks like he is in to road racing trucks..

DJ: the company i got my watts link from is Totally polished.

YouTube - TP Watts-Link

almost the same as the one i got but mine has thick polished aluminum cross brace and better looking center brace. Do not remember who i got the boxed trailing arms from but they are a ton better and lighter then stock. Will get pics once done welding it up.

I kind of have the same project int he "planning" (dreaming??) stages. My current plans are to use a Dropmember C4 version (or the C5 version when it comes out) made by Nate at Porterbuilt Streetrods. He is on this site often in the suspension section. Here is a link to the C4 thread..http://67-72chevytrucks.com/vboard/s...d.php?t=212001

I also am planning to stick with the stock style trailing arm suspension, but modify it like a NASCAR chassis. They use it on the road couse..

My planned ride height will be about 5-6" off the ground to the bottom of the frame. I might use airbags, take note of the cars that ART brings to the Goodguys shows and really performs at the autocross event.

just my thoughts.

I actually talked to ART during the fall Grand Rod Run in Pigeon Forge. The did very well in the small autoX event they had there this year as well. I am not ruling that out as an option...it is important for it to LOOK AND PERFORM well, and the ART can certainly do a fair job at both from the looks of things.

On a side note I thought I'd throw up some pics of what is going in my TBSS this weekend...

[leftcoast66]

oOo, that looks like that could be fun.

[Super73]

What are you running for a cam and exhaust?

Speeking of TBSS, I'm on the fence about buying my wife a new car in the next year and taking over her 07 TBSS since I use it to tow my truck or by myself a used CTS-V. If I took over the TBSS, I think a nice little 224/230 110/114 would be kind of fun.

Kooks 1 3/4 headers, catless Y pipe, electric cut out for exhaust, the cam is 22x/23x high lift. Its a custom grind from AI. They put a set of their heads on a GTO with a 332/336 cam, and full bolt-ons and it put down 487 through a stalled A4 (this was with stock in take I believe). So I am hoping to see some decent ET's. I am working on a nitrous set up as well...something along the lines of a 100 shot. I'd kinda like to be 12.0 @ 110 NA, then 11.6x @ 115 on spray...I guess we'll see what happens...with AWD leaving on spray, it would be a beast on the street from a dig.

I'm doing suspension work also though, so it will still be able to corner and brake...Coilovers should be here very soon...it already has upgraded sways, and its lowered...but I want a better ride AND handling.

You obviously have to do what you need to do...but I'd get the TBSS...its just too awesome seeing the look on peoples faces when they get spanked by an SUV. If you are able to hang onto it, I think in 20 years it will be worth some dough too. I'm really diggin these classic SUV's...like a late 60's early 70's blazer...the TBSS is the new equivalent IMHO.

Either way the TBSS is staying. I just don't know if I want to get her a convertible of some sort as thats what she originally wanted then drove the TBSS. She felt a vert would not be as practicle with out having something like the TBSS for the future. So with that, buy her a vert or me a CTS-V. If I got the V she would drive the TBSS, if I got her a vert, I'd drive the TBSS..

That 487rwhp seems a little high IMO going through an auto.. I'm not really calling BS, but it just seems a bit higher than what I have seen through other major LS shops with a LS2 with out dyno tricks. Any idea what the compression was? I'm assuming you meant 232/236 not 332/336.. Also, when you say full bolt on's did it have a EWP, Dual/single cut out or through the mufflers? Was that with a short belt? Got a link to it? I'd be curious to know all the details.

I looked at a few used CTS-Vs earlier this year. Nice and all, but go take a look at a G8! If I were to get a new car, that's what it would be.

Here is the link...It is legit, if you read on other guys dyno'd their cars at the same dyno and they made similar power to other dyno's they'd been on. There have been other GTO's make similar power with TFS heads...AI flat knows what they are doing I'll throw up a link to their site also...

found these on ebay while back

[cdhc10]

these too

[cdhc10]

try these

[joeys66pickup]

what happened to the days when 16'' rims were Big? jesus wheels like that scare the crap out of me(how you gonna drift?!?!)

[Legend56BC]

Hi All,Well I am mainly a roundy rounder(oval track stock car "truck") but for a 65 C10 I would keep the trailing arms because you could go with all types of rear coil spring setups and I would go very light on everything I could.The idea is to keep the truck safe,light and legal for the street.I would try and balance the weight around so you are sitting in the 50% area of the truck(we are talking shortbox right) and have the weight for going left and right in the right places and scale it until it's as good as you can get it.On my streetstock truck I had my battery mounted behind me in the box area on the bottom part of my frame to keep the weight low and to the left so you would want to keep things like that low and centered as a balancer for going left and right on a road course.Put your fuel cell or tank(not stock tank)in the rear to counter the weight in the front etc....As for parts it's really up to your budget so the others here have get ideas and I wish I had the dou to put stuff like that together!When I had a legend car I would go oval track racing but the drag racing track in my area had a road course (Mission Speedway Abbotsford BC) and I would have to take weight out and totally change my suspension setup so what will happen is if you want to drag race more set it more to that deal but if you want to road course more set it more to that venue as a street truck...I really hope you get what I'm trying to say here....I'm a better doer than talker.....

[D13]

What about a 3-link with the upper link wishboned to the axle? that would seem to limit the side-to-side while allowing up/down travel (assuming all joints are shperical type).

[joeys66pickup]

Legend56BC do you have a build thread on your truck? It is so Perfect! god must be fun as hell to drive

[Legend56BC]

Yes I do have the 2 builds scattered around my other groups,what I will do is put it all together and post it on it's own.Thanks!We are already starting a new build using a 76 Chevelle 4dr chassis 115" wheelbase and caging it and putting the green 68 Chevy C10 fleetside shell on it.We will be cutting down the front and rear sections of the fleetside box sides to give it a shortbox fleetside look in a balanced way...I will post it in a separate thread as well.I feel rare being a roundy rounder in a pit of Drag Racers!

[joeys66pickup]

THAT will Be Sweet! and a roundy rounder is only someone who hasent hit the straightaway yet,then your temporarily Drag Racing!
