what is the best bulb to buy for the gtc that will go well with LED DLR'S?

and secondly 

remap or race chip i have no idea which would be the best option 

thanks

1. Headlights, I'd 100% recommend these Philips ones:

These are easily as white as the LEDs and are super brights. I'll need to find some pics of them on my car for you.

2. Remap...they're tailored towards your car and not just a generic things like a race chip. Not saying race chips won't make your car feel quicker but they're not as safe as remaps and also are a bit basic with how they help deliver that extra power i think. I'm not an expert though! Ha
