Finally got some riding in with the SRP rotors on, and the only conclusion I can post is those f*ckers rock! The rear rotor will only cost about 80 or so and is solid cnc stainless steel. The only difference between galfer and srp rotors is a simple zinc coating, which shouldn't cause a 40 markup or so! Although the pic on magic racing's site shows them being like a 'chain link' shape they are actually a wave rotor for the warrior. Combined with EBC severe pads they pack quite a punch in stopping power, especially in wet and sloppy conditions. If you have a grit problem with your current rotor this is a easy solution, the wave will keep your pads clean as new!
As for the Razor2 I would say the same, damn good tires! They won't hook up quite as well in very soft layers of dust/sand, but you'll forget all about that once you see how well they handle at very high speeds, very predictable/sure footed regardless of terrain. These tires will really stand out in the forest, they tend to love moist soils, mud, and rocks. Very tough construction, they are made of a very hard rubber also which is probably why they spin a little in the soft dust. That tough rubber gives them quite a lifespan and almost no foldover once so ever, 99.9% puncture proof! I would say they are well worth the money! I've heard that the I razors wear down quite quickly, but definately not the case with these, even pavement barely touches them! The I razors were probably developed with softer rubber anyway, especially for very soft and loose terrains, where a little more tack is needed.
