Ain't high HP fun
You need more practice on lifting the right foot quickly a little, not all the way off though, to regain traction and steering under severe loss of traction
My old pump gas Duster made 560 HP to the rear wheels(727 HP and 720 Ft. Lbs. torque to the flywheel) it would get loose in a heart beat on the 315x60x15 (on ten inch rims) M/T ET Street radials, not so on the same size ET street bias plys tires on the street
The radials where quicker and faster at the track than the bias ply where
That car was a ladder bar with coil overs and a diagonal link with full wheel tubs.
Be safe
