I didn't actually get mine fitted by them. A friend and I went there and spoke to them about a kit for his car. They showed us some of the cars they have done and we were both impressed. My friend is getting his kit fitted by them. He also has an R33 gtst.
He is getting GTR front bar and side skirts. The body kits are not fibre glass, but rather FRP, which has a bit more flex in it, so doesn't crack as easily. They also use two pack paint (spelling), and heat treat the paint. What they do seems really good as well as a good price, thats why a recommend them.
