The Spoon TWINBLOCK caliper will bolt right onto EX and DA knuckles, the problem is they will require a rotor that has a different hat offset. The solutions exist above. I personally use the fastbrake rotor. Its a 2 piece design, quite pricey initially but the actual rotor can be replaced for a fair amount. Spoon can sell you a 3mm under-rotor spacer that they use when using their calipers on non-5lug setups. I wouldnt want to go milling a $1300 caliper. So yeah go get your money back....Wow, Really, no bracket needed? I paid for the calipers and the shop I do bussiness with charged $350.00 for a bracket he said needed to be made! I gotta get to the bottom of this!
I dont remember what brand im using but when I bought my H&R spacers they came with 8 extended studs. You will want to call fastbrakes and order the rotor, just tell them you have DA knuckles and need the correct 2 piece rotor to run Spoon calipers. You will need a minimum of a 15mm spacer, I would recommend H&R, they are approved for use in Germany which has some of the strictest standards. I am using a 10mm spacer on the rear to almost match the wider track of the front. If you order a set of 15mm and a set of 10mm spacers it will save you from buying studs separetlyOk what extended lug studs are you using, ARP? I have da front knuckles and sw388 rims like you but which fastbrake rotor and where did you get the spacer. Ha I got the same fullrace traction bar too!
