i had a problem with one of my ATE calipers on my doka and a brand new set of girlings on the shelf for a caravelle project that ive got in the garage, the caravelle is turning into a long term project as im having way to much fun with my doka, so instead of spending money on the ATE calipers ive done a swap and will save that expense for another day, so now i can come out and play again
