Project Fiesta ST-Improving the Brakes with mountune USA
So far we have improved the handling and shifting on our Project Ford Fiesta ST with some stuff from ST Suspension and mountune USA. We are very impressed with the base car. If you are into tuning FWD Sport Compacts you can really appreciate just how good this car is from the factory. If you have built Turbo Hondas or perhaps a Sentra SE-R we equate the Stock ST to one of those cars with a T28.
The car is a lot of turbo fun but with solid OEM reliability, great handling and OEM refinement. On the track the car has proven to be exceptionally reliable putting down lap after lap with not a single problem. No overheating, no fade, no unbalanced handling and most of all, the brakes are up to snuff for track abuse even stock!
We did want to improve them a bit though. Our OEM fluid was getting heat cycled and thrashed and the brake pedal was getting spongy. Now was a good time to get some better brake feel with some mountune braided steel brake lines and improve fluid fade resistance with some Motul RBF 660 brake fluid.
