How low can you go

Looking at putting air ride on my 66. I have a complete Alston chassis front and rear. Question is anyone running that combo and if so how low can I go as far as the Xmember to ground clearence. Im going to switch from 26" tire to a 25" tire front and switch my 33" to 31" rear. If you have this combo would love to see pictures at ride height all up and all down.

I will be putting 18" wheels all around or maybe 20" in the rear with a 31" x 18" Mickey Thompson radial.

If you have pictures please send to shelly40@mchsi.com I need a visial before I pop $7000.00

thanks

Why do you have a Alston chassis?

You have 33" tires on the back of a Nova?!?!?!? I'm running 33's on my son's 4Runner ...and it's been lifted! My 63 SS has 26.75" tires on the back and they seem tall.

The car is a true pro street but Im going to combine pro tour with pro street. Tires are all tucked under. http://s534.photobucket.com/albums/ee343/66novaprostreet/?action=view&current=P1020005.jpg

His car has the bolt on G-machine Front Clip.... it is a piece designed for
handling & street use.

The rear is a 4-link with coil overs & a sway bar....with the right spring rate & shock adjustments & tires, he can whip this thing around any road until that big block drinks the fuel cell dry..... :)

Your right Mike drinking gas faster than I can drink a beer. Mike you have been real helpfull through all my emails. You have to remember Im an engineer so anal goes hand in hand.

How about this low, stock front end with cpp and air over shocks on all four

Looks great what all you have in the car?

Do you have any pictures of your air system?

I can go down about one more inch but I would have to have a new oil pan and scatter shield. As they hit everything now.

Do you have air on that 66 3DTim? If so what system do you have?

Anything is possible.
This is a 64 Impala we built.
It runs a 26" front tire and a 31x18x20 rear on a 20x16 rim.
Its a full air ride system with strong arms in the front end and custom back half chassis with 4 link in the rear (similar to your old skool pro-street).

I can tell you that a 9" rear housing pinion is lower than the 12 bolt so that will help. However your issue or hold up will be the stock trans tunnel. From the sound of it, the driveshaft will hit before you probably reach your "desired" drop height.
This impala has a completelty fabricated new raised tunnel so that it sits this low without driveshaft interference.

On the brighter side, I still think you'll get it low enough with the stock tunnel to still look bad azz ... it just wont sit on the frame like this without major reconstruction.

BTW... nice looking Nova !

You're other limiting factor will be the wheel well.
You'll see in this pic what we had to do to the wheel tubs (look at the welds). They are as larger as they could be (resting on the package tray above). This is so the car can be slammed and not have the tire resting on the wheel well. There is still about an inch of room between the two.

A. Not any lower than this.

I built my rear of my Chevy II to tuck 33" tall tires and accomodate the tire growth on the top end. You can put the crossmember just about anywhere, but you knew that since you're a mechanical engineer, right?

As HRBS mentioned, there are other factors that will limit how low the car can sit, as an example, the top of my wheel tubs are higher than the original package tray location, and I had to notch the top to fit around the B-pillar.

The '65 Chevelle Outlaw 10.5 car I built, we positioned the rear crossmember above the original outter frame rails with a Z. Here is a photo without the engine, but with 33x10.5Ws and the rearend at ride height. We had to do the same thing with tubs on this car. In both this car and mine, the transmission/driveshaft tunnel comes up to my elbow.

Do you have air on that 66 3DTim? If so what system do you have?

No it is coil over front and rear!

All great pictures guys great looking cars. My tubs are real high past the package shelf. I'm also going from a 33" tire to a 31" tire. The rear is not the problem its the front. I calculated putting air on my cross member will be right at 1" to 1.25" that is good just in case I get an air leak I'm not on the ground. Right now the picture on here the cross member is 5" off the ground. I can live with a drop of 4". The rear I could go down 6 or 7" no problem.

This will be my winter project along with some other changes. Fall is getting close and I want to do some driving before the snow flies. Besides when I pick out my wheels I'm looking at 6 to 8 week delivery.

Question: should I go with 20" rear and 18" front or 18" rear and 17" front? The rears will be 15" wide to hold the Mickey Thompson 19" tire

All great pictures guys great looking cars. My tubs are real high past the package shelf. I'm also going from a 33" tire to a 31" tire. The rear is not the problem its the front.

If the front is in question, then the cross member will again not be the issue. I moved my engine back 5 inches and up 4 inches. Should be no problem for you, the floor pan and front frame rails will be your limiting factors after that. If I took the springs off of my front struts, the front would rest on the frame rails...how much lower are you looking to go?

Like I said the 1" to 1.25" will be great. Like you said the pan and headers will become an issue after that. Im good at 1.25". Im going to mock up some stiff links and put them in place of the struts just so I can get a visual.
