In my defense regarding your dislike for the body kit and think that most are lack of thought and more for looks.. The body kit I have is well thought of kit with bigger opening, dedicated oil cooler ducts inserted between the bumper and oil cooler, This Feed bumper is the only one with upgraded driving lights in factory signal light area, wider fenders for wider wheels and lower offset wheels, rear flares for similar reasons as front, Rear autoexe insert to maintain 99+ RX7 adjustable wing but with better wing deck. CF rear diffuser for better underbody flow (same with Feed sides)... unlike most people who just put aftermarket bumper and no undertray, I actually spend far more time cutting different undertrays (currently using Mazdaspeed under tray and factory) to flatten out the bottom for functionality.
Contray to its looks, Almost all the parts exterior to this car have been thought of in its functionality.. including the small useless side mirrors
And yes, I have made multiple high speed run and noticed much stable run (165+ MPH run). I been in FD game for over a decade and I'm not going to just build something to put body kit on or put less quality parts on just to put it on. That being said, interior CF parts are the only thing that doesn't function and all for looks
And also this is the reason I also have an SSM FD that's more purist car..
All rare Mazda/Mazdaspeed parts will go on this FD.
