The reason why your having the traction problems with the Spec and not the Prelude is because of one thing....TORQUE!!!
The Spec V can be launched correctly but, it is different to launch than most FWD's because of the low end torque. I rev mine to around 2000 rpm's and FEATHER the clutch out, and feather it out again going into second. You cannot rev to around 4 grand and dump unless you are trying to win a burnout contest.
Yes the stock tires do suck and a good set of sticky tires will help, as well as better motor mounts, and lowering it will help also. I have done all but the mounts.
Oh, and the LSD is Helical not a viscous type, and you really cant do any better differential wise for the Sentra. The Helical has received a lot of praise from the media and does wonders for the car.
Your traction problems lie mostly in technique not the car. A little practice will help it out greatly. New tires will make it feel like a new car though and should be his first mod.
