An LSD will help save the 915 as it does not allow the dif to slam into the sideplate under extreme torque. G50 is waaaay stronger, I would think LSD not manditory.
Gearing is proportional to HP. You can grow into a set of tall gears quickly with a 930. If using the 915 you must keep the 930 under 350 ft/lb of torque for many reasons, one of them being gearing. You can blow the tires away in 3 gears with that torque and quickly overrev the engine.
As for brakes I use stock SC brakes. Well maintained system and good pads will lock the tires up on the street. You cannot brake any better than that. Fade is not an issue on the street as you only stop like that one time then run home.
