I looked through the forum but couldnt find anything- I am lazy, don't want to build anything and would prefer to just through something in the back of my car and be done with it ... obviously needs to cater for Granite, Notorious and Kraton 8S - my boot is 90cm deep by 116cm wide - preferably no wood - what do you have, what are your experiences especially with different hight of ramps - there seem to be a lot of smaller stunt ramps 15-30cm high not sure if those will do the trick - so what have you got or what have you tried??
