+1 on the Nittos. I have been using them - on my 3rd set in 10 years.
Our 2 Zs have the 285 555 G2s on the front, and the 315 555r (drag radials) on the rear. I rarely drag race, but the Nitto drag radials DO stick much better than the GY GS D3s do, and I find the combo do 'behave'*quite well (IMO) in the mountain twisties and up to ~ 50 mph in a straight line in heavy rain.
*when they loose traction, there is nothing sudden or unexpected. They just begin to skid gradually, thus requiring normal steering and throttle adjustment: no sudden panic maneuvers required!
As for the GY GS D3s, Road and Track (10+ years ago) did a comparison of many sport tires in which the GY GS D3s performed very well between dry and wet grip. IIRC, they rated ~ .9± on dry and something like .85 on the wet skid pad. (I had a situation where the wet grip saved my bacon when meeting another car that had drifted across into my lane on a wet curve. I was already "pushing the limits" myself and had to suddenly crank in A LOT more turn to avoid a head-on crash. Those GY GS D3s took it all in stride w/o a hint of slipping. WOW! Was I impressed!)
By switching to the Nitto drag radials, my launching traction at the 1/4 mile contests was much better than the "D3s", true. But, w/ the "G2s" on the front to plow aside the sheeting water, I could live with compromising the wet performance of the "D3s" for the few times I got caught in the rain.
I hear good things about the Michelin P2s, but bigger wheels (bigger than 17") might be needed to fit them (e.g., 18"/19" staggered wheels is common). Hib Halverson may have some print data on other tire options for both street and track tires he may have researched.
