One dust boot was damaged so ordered a spare parts from service. Got two caliber rebuild kits instead. Is there a possibility to get just one dust boot for front brakes or do they always sell the full kit?

Just noted that Worms have released a coil set for GR Yaris. Is there any good performance metric data for these various coil packs available for GR Yaris? Found a good and informative video in YT but it is not GR related, but would like similar data for GR Yaris also. I asked worms racing...
