Of for this years Nightrally, will see if I can take same piccies tomorrow.

Sorry, had to dig out one of the cars taking part in this years "Nachtrit" from deepest darkest Belgium yesterday ...
As it's dark as I get home from work this time of year you'll have to wait at least til next weekend for some piccies from the inside ...

Some general piccies which give an impression how they are fitted ...

Caliper with the (radial) mounting holes visible...

Thanks Theo. Don't go to a special effort to photo the inside this weekend - but next time you have T'Kreng on the hoist I would be grateful if you snap a couple.

I had never seen radially mounted calipers fitted and am curious about the mounting braket used. I assume this is fixed using the original caliper fixings to the strut. I don't suppose you took any measurements of the bracket before fixing?

It's still on axle stands with the wheels of do that's not much of a problem

Correct

Euhh ... aslo correct   I'll get a tape measurement in the piccies for comparison.
Will try to measure the most important dim's

As a temporary fix for the tyre clearance problem I made up a pair of wheel spacers from some old rear brake drums.
See how they are going to fit tomorrow ...

Respect for the enterprise, and the workmanship, Theo, but universal alloy spacers cost about £3 each, and weight  a lot less.

Well the search for the drums took me more time than the actual machining, which was less than an hour.
They indeed aren't light but then it's a temporary fix.
As soon as I have sorted the springs/struts they'll be removed.

Viewed from above...



Bracket is 16mm wide where it is mounted to the strut;
At the back it's 21.5mm wide;
The mounting holes for the caliper are centered at the back;
Distance from face of hub to heartline of disc is 65mm;
Discs are 28mm thick

Viewed from the inside ...



Total height of bracket is 188mm;
Mounting holes are 148mm apart;

No decent measurements of the distance between mounting bolts and rear of bracket.
This also depends on the disc diameter, mine are

Thanks Theo for the nice pics and data.

I must have missed a thread regarding the need to spacers. I take it these are being fitted between the disk hat and hub? I might be dumb today as I can't visualise how this helps tyre clearance. Wont they move the hub face more outboard, thus bringing them closer to the wheel arch? Or is it that more clearance is needed inboard for some reason?

The spacer goes between hub and wheel, thus creating more room on the inside between tyre wall ans front upright

Decided to go for adjustable coil overs on all four corners of 't Kreng.
Ordered through the (local) Dutch firm AST-Suspension.
Only problem is that space for rear top mount is a bit limited ...



But that shouldn't be problem as they will make up a set to order  
Also the rear suspension turret is a bit narrow ...



Luckily they can supply rather narrow springs to sort this issue.
The set should be ready just before Christmas ...

Front suspension upgrade nearly ready ...
Had the brake hoses shortened and other banjo-ends fitted ...



Both struts now in place ...



Front of the car stands slightly higher now.  With the lower spring seat at its lowest setting (with the springs just seated on full droop that is) the car sits a bit higher then with the old struts.
Will first drive the car a bit to see how she handles with the new and much stiffer springs. To start with I have put the dampers at their softest settings.

Only need to bleed the brakes ...
