I absolutly love that kit and I think its even better that they are going to manufacture it! I dont think it looks anything like that shitty JT Evo kit, as that is nothing but stick on garbage. This kits looks much more refined, and fits the origional lines of the car rather well.
Perhaps since you are in cahoots with the guy in charge of this, us oh-so-critical consumers can offer some styling tips, although everyones opinion when it comes to bodykits it different. Personally, I think the drastic indentations on the rear facia closest to the wheel wells are a bit over accentuated.
The front is perfect imo, EXCEPT that 'stock' looking plastic around the lower fog light assemblies. I think having custom inserts availble (mesh, verticle/horizontal billet) would be much more appealing to the consumer.
What I like about the kit is that its understated, but still noticable enough that there is an aftermarket kit on the car.
Since GRIP debuted their kit, that might start to catch on with a few but I think if your buddy can replicate this, in a quality way (perhaps with some 'tweaks' to set it aside from the Kenstyle kit) I perdict it to be very promising.
By the way, do you know what the kit will be made out of? Plexiglass, urethane?!? What?
