I'm sending back the ramps I bought from Griot's Garage, as they don't clear the Z...I managed to rip out part of my chin spoiler on the way down (snapped back in, thankfully!), and they aren't as wide as I thought (The ad said they are 9.5" wide, which is true, but there's about 2-3" wasted for side-curbs...)
So, that brings me to race ramps. Since I don't have a yard stick, I can't figure if I just need the 67XT by themselves, or, if I'll need the extenders too.
Anyone got 'em? Can you confirm what's needed?
