rj Posted May 21, 2018 Share Posted May 21, 2018 Does anyone happen to know the detailed specs of the brake discs used (at least on older cars)?Acording to the Brembo website I've found this:Diameter 232mm, height 26.2mm and centering diameter is 66.7mm. Thickness is 9.6 wand wear limit 8.3mmThere's nothing about the bolt PCD nor the thickness of the flange.Does anyone know the exact data - or where to find them?Thanks/r Link to comment Share on other sites More sharing options...

rj Posted May 22, 2018 Author Share Posted May 22, 2018 Yes and no:In the second link there's a drawaing and some text.Bolt circle 88.61 in the drawing; 86.61 in the text.I would guess that the drawing is the correct, and I can measure the pcd within a couple of mm...Thanks /r Link to comment Share on other sites More sharing options...
