Really sweet! You could publish dimensions, a materials list and instructions and not loose 3 sales. Very few have the ability/equipment/etc. to do that knid of work.

Yeah, I'm curious to see what it looks like with the final wheels on. I'm planning to use 17" late model Mach 1 wheels, so it may look a bit empty in there. The brakes get better cooling airflow inboard like that though, and the real advantage is in the drastic decrease in unsprung weight.

Also, you're correct in noticing that the halfshaft acts as the upper control arm as well.

Do you mean with respect to ride height? I set it up to be about at stock ride height, which is appropriate for the car I'm building. The rear shocks are adjustable coilovers, so I can lower it that way to a certain degree as well.

Dude, do I have a solution for you!

Newstalgia’s modern billet aluminum wheels

Example at http://www.mustangweekly.com/2004/june/power/power-04.asp

Here's a detail pic http://www.mustangweekly.com/2004/june/power/wheel.jpg

They are aluminium, so lighter than steelies, come in larger sizes, and are MORE like the originals than the late model mach wheels because the blacked-out bits are part of the wheels, not gaps. Normally not my cup o tea, I like open wheels, but it should suit all your needs. I love the brake setup you've got too. Oh, and I guess you made those spindles or whatever you care to call them, the aluminium looking bits at the ends. They look like serious chunks, I'd consider skeletonising them, to reduce the unsprung.

Very nice. Those would be a great fit. However, what about showing off the 12" slotted & cross-drilled Wilwoods up front?

Route666 · Oct 24, 2004

Well, compare those and the late model machs, see if they go together, then you might be able to use the mach on the front and the Newstalgias on the back. Maybe. I think it'd work because the fronts will be open and rear solid looking. If it were the other way around it'd look funny, like a FWD rice box I guess. *shudder*

Wow, very nice work.

It looks STRONG.. WAY STRONG.

What are you planning on running up front?

The front is a Mustang II-type dual A-arm setup with tubular arms, adjustable coilovers, and 4-piston Wilwood calipers on 12" drilled & slotted rotors with aluminum hubs.

The A-arms, springs, shocks, & rotors on the front right now are cheapies for the trip to the plastic media blaster and the paint shop. Similarly, the old leaf springs & solid axle are going back under the rear.

Thanks for the compliment!

Wow, great looking rearend. I've just got one question. With the half shafts acting as Upper control arms, what happens when the force pushes the top half of the spindle inwards. Say a cornering situation in which the frictional forces cause the tires to want to stay planted, when the body is rolling in the other direction. This would cause the spindle to wish to stay perpindicular to the road surface, while the lower control arm would be pulling inward. Wouldn't this cause unnecessary strain on the halfshaft itself, or perhaps a pushing onto the differential? I kinda see this as a system in which the main driveshaft of a car rides. Just imagine if the yoke wasn't able to ride inside the transmission.

I'm only a novice, so don't take it too hard on me if I sound like an idiot.

Great looking piece of work though, really hardcore.

Yes, the load case you mention does stress the halfshaft, but not unnecessarily. The shaft itself is designed to handle these loads. The bearing assemblies both at the diff and at the hub are designed to take thrust loads (along the axis of the halfshaft) while still functioning smoothly. It's basically a Corvette system, which is very popular and widespread in the hot rod world.

A couple more interesting pics from today:

Route666 · Oct 24, 2004

Sweet colour!

Nice motor too. You just HAVE to get a Kenne Bell for it. (If you can get them for 2 valves.)

Well, it's about to go to the blaster to go down to bare metal (everywhere). Haven't decided what color to paint it yet.

It's a 4 valve!

Fostang · Oct 24, 2004

You keeping the tremec t-45 with it? Or upgrading to a t-56?

Also what do you have planned for your brake set up?

reenmachine · Oct 24, 2004

Keeping the T-45 with it on this car. On the next car I'd really like to use the new 5.0 Cammer with a 6-speed -- just have to get someone to pony up the $15k for the engine!

The brakes are 4-piston Wilwoods all around, 12" vented, cross-drilled, and slotted rotors up front riding on aluminum hubs. I have a power dual master cylinder for it but I don't know if it'll fit yet. I may do hydroboost. Oh, and polished Wilwood dual parking brakes.

wildstang · Oct 25, 2004

Did you move the engine back farther or is that the usual position, just looks like some extra room from the radiator core support and the front of the engine. Looks like room for a v-10 (like the one used in the new shelby )

Also what kit did you use for the front suspension and where did you get the upper and lower arms?

Thanks and great job, you work fast.

reenmachine · Oct 25, 2004

I put the engine as far back and as low as I could get it. It's really close to the firewall.

The front suspension is from Heidt's Hot Rod Shop, and the arms/springs/shocks you see in the pics are their "economy" setup. I have their tubular arms with coilovers for final assembly. I recommend Heidt's highly -- the kit went in very smoothly and the components are high quality.

Sundance · Oct 25, 2004

Class act. Much respect...

Fostang · Oct 25, 2004

Definatly Heidts sells quality items.

Did you have fun making those motor mounts.

I know I sure did with the lack of room once the motor is in the position it goes to measure.

MustangMatt1966 · Oct 25, 2004

i am agreeing with route666 in seeing a supercharger on top of that beast!

but i think its gonna look goofy at the back with the brake rotors inward of the spindles. i mean isnt that the point of big rims? to show off your sexy brakes?

quite the contrary i think. when someone sees the hubs on the back with neither drums or disc, they are likely going to look underneath to see wth is going on with the classic mustang.....

and when they see what and where the brakes actually are...they will realize it was worth bending down on one knee and craning the neck a bit for the peek. that rear end on a classic mustang commands respect!

on a side and somewhat related note, back in the early 90's i used to work at monster motor sports in southern CA shoe-horning 302s in mazda miatas. we eventually managed to fabricate a frame to mount the T-Bird independent rear-end in the miatas. keeping a rear end that could manage the torque, still maintain independent rear susspension, AND keeping those sexy disc brakes on the spindles.

i am currently in the early developemental stages of fabricating a similar frame to use the t-bird rear end on my 69 mustang utilizing coil-overs with upper and lower control arms. i too like having big a$$ disc brakes filling the open spaces of the rear wheels.

at any rate. reenmachine, i tip my hat to you. your classic has beaty AND the beast! that car will look like a piece of muscle car history, yet slalom with the most expensive newer performance cars of today. simply awsome work!!!

Fostang · Oct 25, 2004

Oh and did you have to relocate the oil filter also?

I thought about getting a shorter but filter but it's already small enough and didn't want to give up on the bearings.
