Race Ramps to change the Oil in my Z06.
I lowered my car the max amount in front with C6 bolts and longer bolts in the rear. Dealer said my car is too low and they can't change the oil in my Z06 anymore. So I do my own oil changes. I used to use 4x jack stands under the car alone. It was scary! Race ramps are much safer than just jack stands alone.
No problem with clearance on the ramps but you do need to remove the black spoiler on the Drivers/Passengers side. If your Corvette is as low as mine, Race Ramps worked great for me !
