Front (and Rear) Suspension: December 2003

Wow, I can't believe it's been over 2 years since my last front suspension update.

Well here's the plan: Everybody debates the cut/swap spring lowering method, DMCH or Grady springs, to lower or not to lower the rear....etc. etc... I'm chosing "E - None of the above". I know I want the car lowered, but I'm not sure how much and I won't be until the body's finished. And that won't be for some time. So I need a ride height that's adjustable. Also, there's some debate as to the damping rate of the shocks. Old ones were stiff, newer one less stiff, etc. Again, (call me indecisive) I want adjustable. And they have to look kick-ass. Sooo what's need is a set of adjustable aluminum coilover shocks for a Delorean. I'll just grab my trusty Delorean performance catalog and ..... Oh wait, there aren't any aluminum adjustable coil-over shocks for a Delorean. : ( Sooo back to the drawing board (literally) and the measuring began. Before I could select a racing shock from a catalog, I would need precise dimensions of the original with some idea of my final ride height. Many hours of measuring and re-measuring yielded some compressed, extended and ride height dimensions I could start working with. When I started lookig at shocks, it became evident just how short the Delorean's front shocks really are. Most shock company's shortest shocks were longer at their compressed length than the Delorean's at ride height. Eventually, I did find shocks that matched up almost perfectly to my required dimensions.

Here's a shot of the rear shock installed as I was installing the new Rear Wheel bearings.

One of the next items on the list was BRAKES. The has 10" and 10.5" solid rotors with two-piston calipers all the way around. The main complaint I've heard about the Delorean's brakes is not their sizing, but rather their ability to dissipate heat, meaning they work great for the first panic stop, but then become heat-soaked and fade fater that. I wanted a way to get vented rotors on the D. ( Heck, even the Ford Aspire came with vented rotors up front.) Anyhoo, I've already mentioned that I'll be going with 17" rims up front and 18 in the Rear so a wimpy set of 10" rotors, even vented will get lost in those rims. I need something larger...

   
How about 13" in the front and 12.19" in the rear. The rotors I came up with are slotted and vented, curved vane 13" x .833" and 12.19" x .833". I chose a two-piece design (rotor and hat) for two reasons: 1. Weight savings. 2. Offset adjustibility afforded by a variety of hat selections.  
     

Here's a good shot of the brake system with the stainless line installed.

One tip here: While installing the braided stainless lines I discovered a condition that make make these lines difficult or impossible to remove in the future. Where the flexible lines meet the hard lines, there are brackets on the Delorean that ued to fit snufly around the nut of the original lines. The nuts on the stainless lines are smaller, sallowing them to rotate INSIDE the bracket. If you manage to get them tight on installation, then later, they seize, even slightly as all thingsd on a car do, you will not have anything to hold onto when unscrewing them because the nut on the line is now spinning down inside the bracket sleeve. (If that doesn't make sense, email me. It's a little tough to explain.) The way I got around this was to (purists cover your eyes) grind off the sleeves on the brackets so that the brackets are now just flat plates with holes in them. There are just two sides of the sleeves with little tack welds. I used a Dremel to cut through the welds then pry the sleeves free of the epoxy.

 
     
With the shocks and brakes installed.  
     
This is one of my favorite shots.  
     
Here's a closeup of the rear caliper assembly. The calipers I used are 4-piston ones from Wilwood. The one part of the brake system I still need to install is the emergency brake calipers. I'll be using cable operated spot-calipers also from Wilwood.  
     
And finally on the ground. Now onto the body...
