As title states, I purchase a 2-piece rotor and was excited for the weight reduction and the performance I can get from it. Instead, I find myself hating that the hub and outer of the rotor has surface rust that won't go away because the brake-pads aren't hitting those areas. So what exactly can I do to get rid of it because it looks ugly and looks like I don't take care of my car when I do ..read more

Did a search and didn't really find anything more recent, mostly older posts with missing images of dyno sheets. My catless downpipe abruptly necks down at the end from 3" to 2.5", will this have any noticeable restriction on power/response with a Dom1.5 10cm? I'm assuming it won't because it's far down the exhaust path and it will be about the same as running a full 3" catless with a stock catback which people generally say does not affect power. The car will be on e85 with full bolt ons... Downpipe size restriction ..read more

OK this is probably a stupid newb question but I tried searching and I can't find the answer anywhere. Anyways, when I put it in sport sharp mode I notice it will automatically go back to I mode after awhile and if not it will definitely go back to S mode after shutting off the engine. It seems to run fine while in S# mode so I'm not sure if it a safe guard for something that's wrong with the engine. Thanks for any help! Best, Fitz ..read more
