Congrats on the N-Line!
We're you able to source white LEDS for the rear passenger dome lights (by the door?). The factory ones seem to be a yellow LED soldered into a board
Well, I replaced all of the LEDs EXCEPT those. I don't feel like trying to replace the whole board, so they stay ugly yellow.
Thanks for posting. Care to elaborate regarding in what ways the two cars drive differently? Handling? stiffness of ride? transmission? power delivery?
Handling/Stiffness: the 2019 is noticeably stiffer, but only "just-so". It's also more planted and a little more stable on the freeway, due to the N bumpers/splitters. A prime example is a section of local freeway that has a break in it, and if you go over it faster than about 60mph, you'll get full suspension extension and very nearly catch fricken' air. The 2019 N-Line doesn't get as floaty and "weightless" as the 2018 Sport. I may have been going faster than 60mph in both cars. When you're making a long sweep toward the limit of grip, like the cloverleaf freeway entrance ramps, the car definitely feels more neutral and is a little less inclined to plow.
Transmission: Hyundai doesn't state any different PCM programming, though you would be convinced that there is. It's just as snappy and responsive as the '18 Sport. I can still trip it up and get it to hang for a moment, sometimes, or confuse it inbetween gear changes. But that's really more a product of unpredictable heavy rush hour around here, on top of geography (stop and go on hills and stuff can trip it up easiest).
Power delivery: In a word: better. Because of the stiffer engine and trans mounts, the N-Line doesn't wheel-hop like the Sport can/does. Nailing the gas from a stop, in the Sport, gives a 50/50 chance of shuddering wheelhop when hitting boost. In the N-Line, it's very minimal hop and more one-wheel peel. This. Car. Needs. A. Limited. Slip. Differential. ****, I REALLY wish someone would program our ECUs with the Veloster's e-Diff programming, at least. It's easy to roast the inside tire of the DCT's Hankook tires, when trying to take a corner or powering out of a curve. I think a set of Pilot Sports/Cup would do wonders.
Really, in summary, the car is stiffer, more buttoned-down, firmer in all the right ways, and more neutral handling... all for the better. It also does a much better job of putting power down, the steering is a little quicker and more direct-feeling, the seat bolsters are a little better, and the smaller N wheel is a blessing. I do miss the rear traffic and pedestrian detection, and it did cause me to get small circular blindspot mirrors, partly for the blind spots from the passenger side. The pillars are so damned big...
All the little differences add-up to a noticeable whole; the GT Sport feels more like a sporty slighty-softer touring hatchback, whereas the N-Line feels much closer to a straight up sporty warm hatch.
