Ramp it up
I had the exact same issue and used some 2x12 blocks to gain a bit more room. Although the wood blocks did the job it was not very elegant and I did need a spotter as they tended to slide. I was thinking the longer progressive ramps would be nice to have too but considering how many times I will actually use them, I don't know. The Race Ramp, priced from $300 to almost $500 is expensive for what they admit is 96% air. It is not stated if they are made in USA or not. I'll guess not.
Autozone shows two "Rinoramps" made by Blitz and are much cheaper at around $45 for the 8000# and $54 for the 12000# and both show to have a 17° incline. Based on their sigs, it does not look like either of the guys who said they use these have lowered their cars (yet) so these may not work. Their $54.00 HD model says lift height is only 6" and is 36" long. Based on my personal shopping experience there, I'll guess these are imported from China.
Brute Industries (found on Amazon) has these
"
Race-R Low Profile Sports Car Ramps" for $204 and includes free shipping. They have an 10 3/4° angle and are 56" long, provide an 8" lift and are 12" wide. These actually look good, have good reviews and show photos of a Vette driving on them. They don't state where they are made but I just might buy em.
Another option is the DIY model and are not nearly as portable or as easy to store but are surely much cheaper and of course would not contribute to our national debt unless you used some kind of Brazilian hardwood or something. Found this write-up with photos and sketch on Mustang World:
