On a yellow Z like yours i'd probably go the black.. how much are they out of interest as it doesnt list the prices, cant imagine they'd be very cheap
Veilside is on its way out... Im in the process of gathering bars and skirts. Lambo orange may or may not be continued... looking at red or blue? Havent had a quote from them yet, but the were US$300p/w for 18" on the Enkei website. So... Substantially more here is my bet.
I don't like either, but black... Also, you need to know what colour and kit the car will be sporting before you can pick the rims!
TwinZ type 2 rear bar, Kaminari skirts, Stillen GTZ-R II or 2k front bar. May or may not be keeping current colour depending on whether or not they can match it and how much a respray in a in single shade colour will be compared to getting the kit and guards done in 3 layer pearl.
