I’m interested to read comments from you all. Please flame as appropriate.
Cheers, Adam.

When fitting aftermarket brake packages, you still have to get it engineered as you are not fitting a factory brake package to the vehicle.

Did Wilwood or AP offer direct fit replacements?
No, I was looking for low profile calipers from their range to match the D4 piston area, generally 4 or 6 pot calipers.

Were further adaptations/changes required?
All Willwood et al calipers require a bracket to be designed and fabricated to bolt to the hub mounting points.

When you speak of less than 5mm clearance, is that with the Wilwood or AP calipers and the 360mm discs?
Using the AP Racing calipers as an example, the caliper sits at 203mm radius, (i.e. 406mm diameter) on a 360mm rotor. The D4 18" wheels I have are 410mm inside wheel diameter.

What was the clearance to wheel spokes?
From memory approx 10mm.

What factory 18” wheels did you use to do the testing?
I have the attached wheels.
