If I was to do only one handling upgrade it would be to put tubular control arms on the car. The stockers are made of wet noodles in comparison, seriously
The tubular arms have more castor. And if that is why I would try them in a heart beat. My 81 needs to lose more weight.

I've seen a arms after wrecks. You can crumple one, but it never comes apart/tears.
The amount of force to tear one like a phone book would be enormous.

I forgot to ask you. The uppers are direct bolt on?
I found ones for 58-64 impala, just uppers, for good price.

I will post pictures for sure!
I ordered these arms but just the uppers:
http://www.autocityclassic.com/a-arm...l-arms-5557hd/

Not from this seller but they are made for them. I contacted them and they are supposed to be the same as the ones you can buy at speedway and cpp.

I found them here at sale price:
https://www.ebay.com/itm/1958-1964-C...53.m2749.l2649

Yes, please document this if you would. I'd like to increase my caster as well.

You only ordered the uppers, correct? My upper (and lower) control arm bushings are completely shot. I figure it may be a good idea, while I am at it, to do this conversion.

I recently went through this - had a post going about it. I was preparing to have my alignment checked when I found my lower a-arm bushings were shot, and the upper bushings had started to show some cracking.

I thought about a bushing replacement or upgrade to poly, then decided to go with aftermarket control arms to add castor and decrease as much deflection as possible - in short -go for the best handling I could without major alterations to the car. Tubular upper/lower control arms fit the bill for me.

It will cost more than a stock or near-stock rebuild, so that is a consideration to review.

There are several choices out there. I went with upper and lower Global West arms with the Delrin (or is it Del-a-rum?) bushings - a composite that offer no appreciable deflection. Global West offers a set designed specifically for the C3. They do need greased occasionally. The arms come assembled with ball joints and a poly could spring cushion that you can clock to the spring. it does make installation easier to some degree.

After installing and getting the alignment, with the added castor and modern bushing, this car feels very "planted" on the road - I would do this again.

AS an FYI - The default cushion is designed for the stock/factory spring, so if you have an aftermarket spring talk to Global West before purchasing these arms - they will help find you the right cushion. I did not know this before purchasing, so it caused a bit of a delay for me.

Yes I only ordered the uppers because as many have said here on the forum and also Vansteel suggested that the uppers add that extra caster the lowers only save a little bit of weight.
I have a complete suspension kit from Vansteel on the way and also front rebuild kit for my stock arms.
But after I found this tubular uppers I couldn't resist!
I will change my lower arms bushings and ball joints as well so all in all the vette will have all new suspension installed hopefully this summer!

Are we saying that these upper control arms fit a 68-82 C3 Corvette? And they have extra caster? And they're really tubular? And they're only $89.00?

They are made for this seller originally:
http://www.autocityclassic.com/a-arm...l-arms-5557hd/

And they were at 50% off.
As per do they fit?
Well according to NCRS info they should. Check posts #4, #6 and #8.
Can't say for certain but will post everything when I'll put them on.
