Aftermarket vs. Nismo vs. Stock

[Negreac]

Ok so I've been looking into a number of aftermarket components lately and there's so many choices it's making it really hard to choose. For the most part I've been trying to stick with nismo parts since they are gauranteed quality and officially backed by Nissan, but it's really wearing on my budget not to mention only so much is available here. The other concern is that Nismo isn't the best choice. I've been doing alot of research and it seems that Nismo parts are more for mild racing than anything serious. For example they're flywheel is 14lbs. in comparison to the 11lb. flywheels offered by competitors, their shifter doesn't have a shorter throw, and all of their performance bushing kits (motormounts, tie rods, etc.) are all harderl rubber(I think 30% stiffer) vs. the polyurethane kits offered by the competition. I just wanted to find out if anyone else has noticed this and whether or not they like nismo products or dislike nismo products for any other reasons. I also haven't installed a number of my nismo components yet and am wondering whether the difference in performance will be very noticable since these are more mild parts. I'm really trying to build a quality street machine more than a full out race bucket so even if Nismo is a bit milder I'm not at all concerned, especially about the bushings since I do care about ride quality.
