So I lowered my C6 on a set of a coilovers - and then added a set of ZR1 side skirts and front splitter - so this made ground clearance even more of a problem to deal with.
I have had a set of Race Ramps for a long time - and still use them to do oil changes, tightening down swaybars, etc - and with the lowered Vette - I couldn't use them anymore as the front splitter would beach itself on the front part of the ramp and wouldn't let you pull the car up.
I did some research and found that they sell a set of extenders that decreases the angle of approach and allows you to get up on the ramps.
Yes - the front lip hits the wheel stoppers at the end - but now I can at least drive up on them - and then get a jack under the car and lift it up a ton easier then having to jack up one side of the car, jack up the front, move the other jack - just making a huge PITA.
Also - with lowering the car - I couldn't get the arms for the Maxjax lift under the car - so I ordered 2 pairs of the Race Ramps scale ramps - and it provides the perfect height of getting the car up in the air to get the arms under the car with no issue.
Some of you might say why don't i just use some 2x4's, etc - I tried that with the race ramps and all I did was pushed the 2x4s against the floor and scuffed up the epoxy - so after doing that once I said never again. I got these from Summit Racing - with free shipping, a $20 mail in rebate, and I used some Summit Bucks that I had saved up.
