I don't have a blackwing yet, but my 56" ramps fit under my S2000 - I can't even get a low profile Harbor Freight aluminum racing jack under it without driving up on 2x4s first. Dimensions are on their website so you can measure before you buy, but I have to imagine the 56" would work and are cheaper and smaller to store than 67"Race Ramps are the best. 67" are ideal but you could get away with the 56" model. You can get them in one piece or two piece.
Speedway sells some bundles with wheel chocks.
