I cant tell you if the wieght transfer is due to the front or rear springs because I put both of them on at the same time. Literaly put the car on the ground and drove it to the track. I saw slighly lower 60ft times my best befor was a 1.75 my best that day was a 1.71. But after driving on them for about a week I can tell a major difference once the springs broke in. I pulled out on a road near my house, floored it and the car coming at me was flashing its lights because it thought i had my bright lights on. I didnt just the fact the front of the car lifted so much higher than normal.
