The fastest roadsters are around 6000 lbs. Weight and HP is a balance... if the tires spin you need more weight, if they don't you need more HP
One very fast roadster owner, driver, said he had 5000 lbs. on rear wheels after I told him we had 3000.
Figure the math on center of pressure on that. Even better, figure CP on a blown Hemi lakester.
