Guldstrand kit or Tom's kit?
Disregarding cost & chrome, which one of these rear end upgrades is better? The 5-link is from Guldstrand, see photo:
The upper control arm model is from Tom's. See photo:
Can they be used together?

What about the six-link? There's an article on it scanned in on corvettefaq.com. I think a couple people here have it and it's pretty cheap. ($400 w/VB adjustable struts?) Somebody post that guy's phone # again!

Actually I made a mistake. The Guldstrand kit (top photo) is refered to as a 5 bar - not 5 link, if that makes a difference.

Re: Guldstrand kit or Tom's kit? (71coupe)
Here is my understanding:
The Tom's kit is for drag racing which I think requires a link that is not part of the drive shaft. This does not fix the toe/camber issues with the C3 vette.
The gulstrand kit is what was used for road racing to correct both toe and camber change issues. This is like putting a C4 vett suspension in the back of a C3
The down side is that both of these still use the upper drive shaft as a suspension link. The real fix would include an upper link that allows the fitment of a drive shaft with a slip joint. But Gulstrand still had good results with their system as is.

Re: Guldstrand kit or Tom's kit? (71coupe)
DaveL82 is correct (to a point) ,you are comparing apples and oranges! both are designed to do different things. I have a Riley 5-link in the back of one of my cars,it was designed by Bob Riley (world famous race car designer) now known as "Riley-Scott", as was the unit Guldstrand sells, as i remember. It was designed for SCCA competition under the rules!. There also was an a-frame/coil over rear suspension sold by John Greenwood years ago that made the half shaft a NON suspension part BUT again this was for IMSA racing (where HUGE sums of money was spent to try to beat the Por$ches), and required ALOT of "fab" work to install. If the 6-link rear suspension worked, the guy would still be in business!! The problem is MONEY and no one wants to re-design anything for a car that has been out of production for almost 20 years (at least nobody with any business sense).The C-4 rear suspension is a derivitive (sp?) of the Riley designed 5-link. BUT the Riley (5-link) is designed to work in a 63-82 chassis with 63-82 suspension FOR racing, it is (so i have been told) streetable.If you want C-4 or C-5 handling you will have to BUY a C-4 or C-5.I DO NOT mean to flame anyone but, I believe it`s as simple as that. There is no way an "old style" car will ever handle like a new one, (or stop like one). ...redvetracr

redvetracr - thanks for the education. I'm planing a rear suspention upgrade with VB's Smart Struts & 3" half shafts. I'll probably go with the Tom's upper control arm kit but I was just curious about that 5 bar setup.

I have seen the Canadian's work and it is first rate. I have not seen it installed or talked to anyone who has used it. He quoted me $350 for the setup for my 71. I plan to try one in the spring.
His name is Rick Taylor and he's in Pewticton, B.C.
I don't have his phone number.
Anyone up for a GP?

Stingy, what did you have to do to install the 6-link? Did he provide the mounting hardware? Any welding needed?
And, please give us a name and number. :yesnod: :yesnod:

Re: Guldstrand kit or Tom's kit? (74-Roadster)
How does this kit deal with the half shaft yokes?
I would like to have a name, address and / or phone number for the guy building these. It might be a bit late in the year for me to take a drive up there (sorry Stingy) so I would be interested in a kit with instructions on how to set it up.

Re: Guldstrand kit or Tom's kit? (flynhi)
Just a quick note. You can actually use the 5 bar & most of Tom's stuff concurently. There were a few parts like the upper brackets they didn't think were adaptable, but I actually had one of Guldstrand's dudes on the phone with Tom discussing combining the 2 systems. Finally I decided that after all that cost, it just made more sense to have Morrison build be a frame from the ground up & use coil overs. That is what the next version will have IF we ever finish this one..

This is from Cars Componets Design -circa '90. They are out of business now. It looks like a good idea/design.
