I would want to get nitto 555r drag radials on a s2000 but u need it to spin a little and ive heard that the s2k hardly spins at a drop at 6000rpm's so is this a good idea or no. if not would it help if i raise the tire pressure so it grips less to get a better launch.

 

Hardly spins is inaccurate. The issues are 1) the clutch won't take slippage so you must drop it hard at >VTEC RPMs and 2) you want to keep it in VTEC for best acceleration. I suspect a clutch upgrade would help immensely but what's available on the market today doesn't seem to handle the slippage required.

 

how about tires are raeally good tires that grab good to get also if i purchase a good clutch

 

I'm no drag racer so I can't say. However, the issue is partly too MUCH traction with the stock tires and R compounds. I've wondered if a narrower tire or less grippy would be easier to launch and keep spinning with less stress on the clutch and driveline.
