In this video, I talk about the 3Racing Realistic Brake Disc Set Ver.3, part number #3RAC-AD12/V3/LB (light blue). I also bought the red version, part number #3RAC-AD12/V3/RE. They come in blue, red and gold, I believe.
I tried them on my Sakura D4 RWD and AWD using the stock plastic front knuckle, the 3Racing aluminum front knuckle (#SAK-D4821), and Boom Racing's aluminum front knuckle for the Sakura D4.
Upon closer inspection, it looks like this disc brake kit might be meant for the HPI Sprint 2 cars. I'm not 100% sure of that but I am 100% certain these aren't for the Sakura D4.
If you own this disc brake kit and you have some information on them, which car they're for, please comment below. I'd really appreciate it as I couldn't find any info on these at all. Thank you!
I wish 3Racing made the caliper take the threaded hole for the sway bar without the bracket. The bracket unnecessarily complicates the kit further.
