Additional update:
Still stocking up parts. Got the GR front/rear exterior emblems. Also got the proper GR push button to complete the interior. 11/10 the most important mod of this car
Also picked up some KW x GReddy coilovers for the car thanks to my friend John at TF-Works. Always a pleasure doing business with them.
Was about to order the GR side skirts from Japan, but unfortunately I opted out because of the price. The Zenki version side skirts (from the GRMN86) had an MSRP of $470 each. The Kouki version (which are literally identical) have an MSRP of $1,300 each. The Zenki parts have been discontinued, and the part numbers replaced, so now you can only get the Kouki ones, meaning if I ordered the GR skirts, I'd have to commit almost $3,100 shipped to the US.
That much for just basic, small, polyurethane side skirts is just too much for me to justify. I'd love to get them, but I can get TRD paint matched or a variety of other quality ones for less than half the price. So now I have to determine which ones to get.
