Can't improve on perfection
In all honesty, I can COMPLETELY understand people who put GTR-style bodykits on their GTS-ts.
My first skyline was a DEAD stock R33 GTS-t Type-M, and it was the ugliest thing I have ever seen. Good performer, but DAAAAAAAAAAMN that bitch was ugly. So I looked for bodykits to try and fix up the looks department a bit, and I quickly realised that at the time, all bodykits available for the GTS-t were fugly beyond belief. The only nice ones were the Trial one (I didn't like their front bar, but the rest of the kit was nice) and the "GTR-style" kit.
I eventually chose a hybrid: GTR Front bar (no badge), 400R side skirts, 400R rear bar and GTR Rear Wing............ A combination that I'm proud to say I thought up myself, and has since been mirrored by many many other GTS-ts that I've seen driving on the roads
Here are some pics of my very first skyline. Transformed from a dead stocker.
