Custom Ford Sierra Upright – steering arm – Part 2

Building a 4×4 Locost Rover V8 Kit Car, means making custom front uprights. Ford Sierra Uprights were used as the starting point.

This Haynes Roadster with Custom Ford Sierra Uprights has parts from many makes and models of cars.

  • Ford Sierra 4×4 Cosworth
  • Ford Scorpio
  • Jaguar X type
  • Austin Ambassador
  • Citroen BX
  • Mercedes SLK

I’ve managed to get the steering geometry spot on, plus the new 300m Jaguar X type Discs have now been fitted.

300mm Disc Brakes and 4 pot Calipers.

I quickly made up a circular piece of steel to fit the central hole of the disc. The Jaguar discs have a 63.5mm hole the same as the Ford Cosworth Scorpio discs I was previously planning on using. With the Ford and Jag discs sitting face to face the turned steel bung held the 2 discs perfectly aligned. It was then simply a case of finding the half way point between 2 of the existing holes on the Jag disc. Using a cobalt 13mm drill and the Scorpio disc as a guide, I drilled the 5 x 112mm bolt holes. I’m sure a engineering workshop would have taken a more Hi-Tech route. My method took 10 minutes and they fit perfectly.

After last week, spending several hours aligning the front steering arm ready for welding, in the week in between a length of angle iron fell over and knocked everything out of place. I had to repeat my setting up all over. It’s all done now – so the swearing has stopped.

At the moment, the arm is bolted on, but I think I’ll weld it into place and add a couple bracing pieces. It’s solid as it is, but welding should make it very solid indeed.

Now that the caliper spacers are right, the steering arm is done and one side is complete, the other side can be started.

A brand new Citroen BX rack to replaced the rather ‘slack’ one I’ve been using for setting up. With a good coat of paint, I think the front end should start looking pretty good. I’ll probably powder coat everything black. I have a rebuild kit for the calipers and some special high temperature paint / lacquer to try.
