This is the Manthey Racing stainless steel braided brake line kit for Porsche GT models, replacing the factory rubber brake hoses with a braided line set that resists expansion under hydraulic pressure. It is built for owners of the 991 and 992 GT3, GT3 RS, GT2 RS, and 718 Cayman GT4 range who drive on track days, mountain roads, or push their car hard on the Nurburgring.
Part numbers MT000234A and 99104480638 cover the 991 and 718 GT models, while 99204485615 is the kit for the 992 GT3, GT3 Touring, and GT3 RS. Both kits deliver a firmer brake pedal, sharper brake response, and more consistent pedal feedback than the stock rubber hoses, especially once the brakes get hot.
Yes. Stainless steel braiding around the brake line stops the hose from ballooning under hydraulic pressure the way a rubber hose does. That means the pressure from the brake pedal reaches the caliper more directly, giving a firmer pedal and more consistent, predictable braking response lap after lap or run after run.
Yes. This kit is designed with track days and Nurburgring-focused driving in mind, where consistent pedal feel matters most as brake fluid and hoses heat up. It works equally well for spirited road and mountain driving.

What does a braided brake line kit do?
It replaces the factory rubber brake hoses with stainless steel braided lines that resist expansion under hydraulic pressure, giving a firmer, more consistent brake pedal.
Is this kit specific to each Porsche generation?
Yes. There are two part numbers: MT000234A / 99104480638 for the 991 and 718 GT models, and 99204485615 for the 992 GT3, GT3 Touring, and GT3 RS.
Does it fit the 718 Cayman GT4 RS?
Yes, it fits the 718 Cayman GT4 and GT4 RS under the 991/718 part number MT000234A (99104480638).
Does it fit the 992 GT3 RS?
Yes, the 992 GT3 RS uses part number 99204485615, the same kit fitted to the 992 GT3 and GT3 Touring.
Will this improve braking performance on track?
It improves pedal feel and consistency rather than outright stopping power, which helps drivers brake later and more confidently as the brakes heat up during track sessions.
Is fitting straightforward?
The kit is a direct replacement for the factory rubber lines using the stock mounting points, so fitment follows the same routing as the original hoses.
