UnJustified
- ear-splittingly bad exhaust noise;
- K&N stuffs and cold air intake kits;
- outrageously large wheels and "rubber-band" tyre sizes;
- non-functional big rear spoilers;
- dangerously jacked up 4WDs and SUVs;
- head polishing (waste of hard-earned money and useless for a street-oriented engines);
- HID headlights on any unsanctioned vehicles and angry headlights;
But hey, who am I to complain?? Their money, their honey... lol
Justified;
- lighter and more durable brake disc assembly (billet callipers come to mind);
- lighter and smooth wheel (requires custom wheel fabricator to make or diy?) or hubcap;
- smooth underbody, like that of a shark;
- shaved IN/EX valve guide boss for a better flow without sacrificing its service life (refer to the machinist for more details)
- tulip-shaped EX valves with fillet edge at the bottom of the margin, nail-shaped IN valves with a 30° back cut above the seat and a thin margin with a chamfered edge (refer to the machinist for more details);
- camshaft with lesser overlap and exhaust duration, earlier IN open/close, earlier EX close, EX close later, and lower EX valve lift (talk to cam grinder about this);
- 100% demineralised water with small quantity of non-glycol corrosion inhibitor for the cooling system (works fine in all-year round tropical weather but not those areas with <32F ambient temperature at 1 season or another);
- LED-equivalent bulbs substitute, wherever possible;
- slightly lower ratio gearbox (4.11:1 or 3.9:1 instead of 4.55:1). but for me, the necessity to regularly carry goods and passengers at a total weight of 700 to 1000lbs on mountainous, uneven, and unpaved roads for almost everyday sorta necessitate the use of the standard 4.55:1 gearbox;
- spark plug gap balancing (slightly wider gap with short HT leads, recommended gap for longer HT leads);
- hot air intake;
- 4-2-1 smaller short headers, with anti reversion chamber at the end of the last collector and progressively bigger pipe towards the end of the system.
ok, that's enough ranting for now. all of the points mentioned above are what I considered as such.. cheers
