URAS Tatsunootoshigo S14/S15
You are viewing brand new Tatsunootoshigo from the D1 R34 Driver Nomuken`s (Ken Nomura) very own company, URAS. Tatsunootoshigo are the little pieces that go on your rear brakes that look like sea horses. These are used for when you are having a hard time locking up your rear brakes no matter how high you pull the e-brake up. After installing these, you will notice that locking up the rear e-brake is so much easier. This is done by replacing the little piece on your rear caliper to add more leverage.
