62a = a little stiffer than street (good for daily)

70a = I use these in my Integra, will vibrate when stopped, steering wheel will shake and other parts may as well since car is a little older ( Good for putting the power to the ground, if you can deal with the vibration get these)

80a = Your girl will leave you for your car cause your car will give her bigger orgasms from the vibrations then you have EVER given her! These are equvilant to welding the motor to the chassis (For RACE CAR ONLY!!!!!!!!!)

I sell these if you need a price PM me
