Ok I’ll you know about sailplane. Best place to get brake callipers is of gumtree or Facebook market place usually 700$ and 1000$ complete saw a set on there today

Which type of brake callipers? I may have some parts of a sail plain ill have to check

If you have vin number go to hsv authentication site and it will give you model and option info but i think you’ll have to contact hsv to find build number. I also have a vu maloo r8 if your after any parts or info let me know I have a few spares there
