All TTSPORT kits →Common questions
Will it fit my wheels?
Big calipers need room inside the wheel. Check the minimum wheel size in the specifications. If you're not sure, send us your wheel make and size and we'll check.
Do I need new brake lines or fluid?
Braided lines come with the kit. You'll need fresh DOT 4 fluid and a full bleed after fitting.
Can I fit it myself?
If you're used to brake work and have a torque wrench, yes. If not, have a workshop fit it. Our installation page covers the basic steps and bed-in.
