Okay people...

I don't want a harsher ride but one that will handle better.

I have heard different stories as to ride height problems with the Mono's, RIDING TOO HIGH.

Is the installation the same as the OEM spring?
Do I need different shocks?....will stock shocks work?
Longer bolts?...if so how long?
Shim thickness where spring mounts to rearend?...how thick?

I have done the OEM's so installation is not a problem.

So i was thinking of this from Vansteel

"Also thinking of a rear sway bar...but later"


TIA

i would do the sway bar at the same time you have the spring removed just my 2c's
last year i installed a vbp unit, 385 lbs. spring rate and already had the Qa1's .....i wish i put it in ten years ago, major difference on ride quality and i thought it was good before with the steel spring, even better now........

you can always adjust the ride height with different link bolts, i would start with longer ones to begin with....

66jack

Link bolt???...you mean the bolt for the mono to trailing arm?

62Jeff

Yes but in at least the case of my 65 the spring is thinner and thus the 4 main mounting bolts are shorter.

Yes

They will function but will not properly suppress the bouncy nature of the rear composite spring.

My personal recommendation - don't bother, I hate the one on my 65.

66jack

What about the ride height issues...some people, "i've read" have issues of the car setting higher and fight this.

62Jeff

None for me. When I have an opportunity I'll post a side-view photo of my 65 with the mono-spring in the rear.

66jack

i will check back a little later, meeting to go to..

What process did you go thru to get the correct height...bolts lengths, shims, shocks, etc...

thanks

62Jeff

I'm currently posting from a location with a restricted network, thus no access to my photobucket account until I return home shortly.

It was configured when I bought the car, but looks like longer end-link bolts were the key.

66jack

If you have a picture of the leaf ends and the mount on the rearend that would be great.

62Jeff

Here's the car on a level driveway


For now, this is the best picture I have of the ends, but I will see if I have any others that I haven't put on PhotoBucket.


Edit: Found a better picture.

Jeff:

Which spring weight are you running?

and

how thick is the shim on the rear end?

62Jeff

It's 330 or 335#

I'm afraid I have no idea.

Did you see the 3rd picture I added to my post that more clearly shows the spring end?

66jack

Yes i seen that one ...thats when i asked about the shim...

how do you like the ride?

Do you know what length that bolt is?

62Jeff

I hate it, which is why my original post recommended you not make the change.

The car is bouncy-bouncy in the rear end, even after springing (pun intended) for the pricy "customized" shocks sold by VBP specifically designed for use with the mono-leaf spring.

I don't know what length the bolt is, but I believe it was part of the rear spring kit when my friends (the previous owners) had the spring installed in the 1990s.

66jack

So you can really feel the Bounce in the **** end?
Other than that does it handle or does the rear slide out on you on the corners, more so than with an OEM spring?

62Jeff

Yes very much so, feels like the car has no shocks at all - which I know not to be true because the bounce is actually better (but still awful) with the VBP shocks versus the Konis. The bounce is bad enough you need the seat belt to keep your butt touching the seat on some portions of my local community.

I never drove the car with the OEM spring, and I don't drive it hard enough now to jeopardize traction.

But, don't take inputs only from me, let this thread play out for a few days and see if others have similar or contradictory experiences from my own.

62Jeff

I didn't have a picture of that mount but it mounts to the rear normally, but with shorter bolts since the spring is not as thick as original.

Jeff:

Thanks for the info, I will let it play out like you suggest...

I started with a 330# VBP spring with Bilstein sport shocks. It road too hard for me. I sent it back and got a 300# spring and that suited me better but the shocks were still too hard. I changed to Koni, they are adjustable, and I liked the ride. I got a good deal on some Spax shocks and changed to them because they are externally adjustable. I ran that set up for about 4 years. I liked it. I changed over to a dual mount spring last summer for increased adjustability. I am selling the 300# spring. It has a nice street ride and handled well but not stiff enough for serious sport driving. PM me if interested.

Jeff,

Your car is sitting too high for both the front and rear. I suspect that may be part of your problem.
