I am working on a brake upgrade. Mainly because there are no good pads available for the current brake system. The front is pretty easy to swap out to the PP Brembo's The rear will require replacing the Knuckles and that's an extra $1100. I am also looking to see if I can bump up the power currently factory-rated at 315 HP and no I haven't had it on a dyno, yet. Any suggestions for adding power would be greatly appreciated.
Just go for the 6-piston fronts and 15" discs. The rears are basically there for decoration, so don't worry about putting much money there. If you want to drop a little weight with 2-piece discs, sure, but even that is overkill. The engine is a relatively easy fix. You'll need an intercooler, a drop-in air filter, a tuner and a tune. The first one, do right away. The stock intercooler kills the engine even when it's stock, so it definitely kills anything more than that. I'm not sure if anyone is tuning these yet or if there's a FP tune (which would be the HPP map). When the ECU's get cracked, these will be the guys to do it. They're awesome with Eco's and they have a 2024 HPP as a test mule https://emsinc-tn.com/.
