hi all, got mine july 31, flint mica,(lots of compliments), tinted glass (35% I think) chrome 17's, everything except nav at tustin lexus, paid 43k even. (lots of grinding!) Seems I should have waited a few weeks, but overall I"m satisfied,love the car,164 miles. I'm seeking advise on two points, the first, does anyone know the part # and location to get the the bulb to replace the yellowish running/high beam bulb? The second, I want to upgrade to 18" chrome wheels w/245/50-18. Is this a good size to fill out the wheel well and look sweet without compromising the smooth ride? Or should it be 245/40, I like the built in lip on the dunlop sp sport 2050's as it makes it easy to apply tire dressing without getting it on the rims,any help or tips would be appreciated. Also how do I post a sig pic, thanks again

, hoping to hang out here alot! Greg in Irvine , so cal area.
