Aftermarket Chassis in a 65 Riviera

Recommended Posts

                      Very impressive.......I'd hate to go up against it at any car show when it is finished.

I don’t know, maybe blown LS9, stout automatic overdrive, Vette front suspension and a 9” Ford rear. As I said in the first line, not everyone’s cup of tea.

I'm noticing a reoccurring theme with your posts...

 

If you don't like it, keep quiet about it.  Some like to mess with things, others don't.

 

 

Back on subject:

I was excited when I read the first post about keeping the original paint and interior that I was going to see something near drop in frame wise but alas they cut the floor out of it.  I've only made it through the first page but I'm sure there is going to be something to glean out of it for my Pro-Touring 64.  I certainly like my 4L80E.

I have looked at the arch of the rear section of my '64 Riviera frame when it was bare and I KNOW a Jaguar subframe and IRS could be installed in my car, a major project, but straight forward.

That is what I consider an improvement. A 4 link narrowed rearend on coil overs is Neanderthal. The side rails of the aftermarket frame invade the area of the really strong rocker panels of the existing body. Nice pictures, but why'd you do it?

 

Throw some big wedges in the right front alignment and go find a circle track.

And some people mistake the way it was for the way it should be...  I'm not going to put a Chevy/Corporate engine in my Riviera but his makes a ton of power with a minimum of fuss, the transmission is a very nice thing to have, and the front suspension on a Riviera goes back to the 50's.

The front suspension is way ahead of the stock stuff both in terms of serviceability and actual suspension design.  Looks like it's a clone or tweaked version of a C5/6 Covette, the uprights definitely are.  I like the work they did on the front end, should be pretty tunable for the desired handling characteristics and comfort if they use the adjustments in the sway bar, shocks, and springs.  I would have made the upper arm adjustable in the leg length to be able to set caster and camber a bit easier.

The rear suspension does look like it's a compromise design to fit, since they didn't keep all the central spine of the X-frame they have plenty of room in the chassis for a proper torque arm suspension which would be easier to adjust and more versatile than the 4-link.  It's not Neanderthal but its harder to get more than drag racing performance out of since it's characteristics require a lot more movement on the chassis side of things for adjusting link angles.

The frame probably is an improvement however, you get most of the stiffness of the X-frame from the triangulated center section with the side impact (minor factor) and longer lever arm stiffness of the perimeter frame.  The X-frame is not a great design for anything other than getting the body channeled over the frame unless you use the body as a fully stressed member.  The boxed heavy gauge rockers help but they are attached to the body which is then rubber isolator attached to the frame.  There's a lot of room for movement there, you want something stiff you want a tall section out there at the outside of the car where you can get away with something lighter because the lever arm multiplies how it stiffens the frame.  More work, i.e. less cutting and pasting from other designs, would have been to keep the central spine but cut out the inner rockers and add the perimeter rails and a set of body mounts at the front and back of the doors.  Probably could have kept the original floor pans as much as possible with the rear tub job if they ran the exhaust through the crossmembers like they did in the above.  I do want to see the finished interior.

No, they acknowledge that it is the way it is because they acknowledge that's the way it was.  One cannot retroactively apply contemporary standards to history.  The car is pushing 55 years old.  As such, it stands as a testament to the engineering technology of the time, and the fact that these cars are still capable of functioning well in the current environment is testament to the capabilities of that technology.

 

That's not to say that a stock first-generation Riviera represents the pinnacle of automotive engineering.  It doesn't; there are clearly better cars being made today as technology has inevitably improved. Nonetheless, there is something timeless about these cars, and there is no small degree of hubris associated with the somewhat masturbatory implication that these fabricators stand above the original designers or that the end result of their labors should be universally acknowledged as superior to the original.

Yep, not my cup of tea when a nice original 65 is hacked up because it can be "improved". There's plenty of cars out there that are not worth restoring but would make good customs like this.

General thoughts on 50+ year old cars might be "Oh, an X-frame is an X-frame". But they sure aren't all the same. When I had the frame out from under my '64 Riviera a guy a couple miles north of me was doing a body off on a '64 Impala SS. The differ in the two frames was dramatic. The number of heavy sections was far greater on the Buick and we commented on the added boxed sections as well as the the many extra feet of weld. Without a bunch of detail just look.

The Buick is heavier and has a much more sophisticated rear design with a track bar.

I get together with a street rod builder a couple times a week and we has similar, but not exactly the same taste in cars. We both make generalizations, but neither of us subscribe to the ideas promoted on mainstream TV or the niche counter culture that gives birth to these jobs.

 

The guy wanted all the technology of a C whatever Corvette, should have bought the Vette.

 

Twenty years ago my cousin built a street rod and used a Maynard Troyer built stock car chassis under it, pretty much what this looks like to me. He learned never to do that again.

I am not a good listener. And I rarely ask for help. But I do tend to learn from other's mistakes. If you have a Riviera body, the best thing to drop it on is one of these:

BTW, the highway institute probably picked the X-frame spindly '59 Chevy for the left corner hit just because it was the best "folding" car they could find.

 

There is no way they sat at a table and randomly picked a ;59 Chevy.

Overall I love it, but I guess you can only see the first set of pics without subscribing to that forum.  

 

From a monetary perspective however, I'll never understand doing this because you'll probably never make your money back.  But then again, people that do this probably don't consider $100k a lot of money.  

 

From an engineering perspective, I have mixed feelings.  On the one hand you are creating a chassis with 5 decades worth of technological improvements in metallurgy, machining, fabrication and design and analysis.  But on the flip side, if this is just some random speed shop, can their engineering department really compare to that of General Motors at the height of their influence even with the massive advantages afforded to them because of technology?

 

For the most part, I prefer progress and am disappointed that I can't see the rest of the pics without making another account.  If the guy has the money and it's a reputable stop doing the work, then that would be one killer car in the end even if visually it would look almost stock.

It is a neat idea, and to each their own. At one time, I was all about this. With 25 years of hindsight, I feel now that the FUN of an old car is the driving experience. I love the way my 65 goes down the highway, and while it tracks and stops great, I feel that I am way more involved in the driving experience at all speeds. That is the enjoyment for me, right along with the various noises and smells of a 50 year old vehicle. With my 2003 Corvette, things don't get really interesting until the wind is sucking the side windows out. Up until that point, that car is just simply a point and shoot missile. My Riv is like really good bourbon; you have to SIP it, to enjoy it.

This is a win win as far as I am concerned. The completed car will be a very nice high profile car that will raise the awareness

level of 65 Rivieras at car shows, and because it is so modified, my car just went up in value some more as another nice stock car has

been taken out of circulation. Win Win.

The welds on this project are straight up porn. Gorgeous. Regarding originality, if it makes the owner happy, it can't be that bad. Hope they adjust the firewall fabrication so it isn't literally touching the bell housing. PRL

Here's an older build (the shop that did it is nearby to me though this is the first I've heard of either the shop or the car).  Looks to be a bit more along the lines of what a lot of us would want though:

I'll have to see if the car is still floating around here in the East Bay AND call the shop to see if they know where it went.  They also used the same supplier for the front suspension "The Roadster Shop" which from what I know from the Pro-Touring world has an excellent reputation for suspension work.  Not quite Detroit Speed level but considering Detroit Speed doesn't do custom stuff for anything less than full on show cars it seems, The Roadster Shop looks to be one of the better folks that work off of a formula to tweak a template design for other cars.  I'm going to join Lateral-G and see if I can pull some of the pictures over with the owners permission.

Those look like the Wheel Vintique units that I'm not sure if they make anymore.  Either way they came in 5x4.75in  only last I checked so with the Roadster Shop suspension I bet they switched over to that pattern with the C5/6 hubs

 

I'm not sure if I can afford them but I'm wanting either

Woah, that's a hell of a pretty car. 

 

Never particularly liked brown for paint, but damn does it go with this build.

Notice the lack of the ribbed rocker molding but a contrasting paint on the rocker below the stainless molding.

Yeah, I think that's one of the things that makes it pop the most.  Reminds me a little of the Mako Shark concept from that same year and this Jay Leno video that I happen to have watched just the other day:
