i don't have nismo v2 front bumper, but I got Nismo sides and rear addons from Shine. Their product is hybrid frp, which is supposedly better than regular frp. I had to mod a little bit to make them fit. Here are the pics. My front lip is authentic Nismo, which fit 100% without any modification.
I've heard a few good and bad reviews about M1 products. Some say the fitment was deadon oem and some weren't.

 

Hey Kuhan

How did you mount the side skirts? The Shine kit doesn't have tabs to mount the skirts where the stock one did in the front upper and rear upper sections.

 

Shine bumpers made from different material than Fiberglass right ?

Let's talk about other fiber glass replica and authentic fiber glass bumpers, is it the same quality of fiberglass ?

 

Don't forget that Vis Bodykits makes the V2 also! Mine fits great with little prep work.. Just my .02

 

^+1 I've seen some VIS v2s and the fitment is good.

 

Yeah the Shine kit fits pretty good my only complaint was the side skirt mounting. I'm guessing the flexible FRP doesn't have the strentgh to mount and dis-mount as the stock setup so you have to figure out your own method of mounting. But the body lines are near perfect even with an ametuer installing them.

 

Not the ones I've seen, my Shine kit looks to be strong and flexible enough for daily driving but only time will tell. The authentic Nismo V2 kit is made of very thick and strong FRP that can take a pretty big hit before de-laminating. If I had a wish list I'd ask for someone to do this kit in urethane. The authentic nismo sides are available in urethane and if I had it to do over I would purchase those higher price plastic parts over the flexible FRP just for peace of mind.
