I dont know, I already have an oem spoiler. I suppose I could line it up and see, not right now of course cause the fam and I are gettin ready for dinner but I'll get to it soon and re-post. I'm sure that it would fit then you would just have to trim.
IIRC, the P10 trunk is 43-44" across. I was going to get one for my old car... But, I bought a t I don't think the ebay ones would be that bad. It's just a simple body accent... Pretty hard to Eff up. Just measure the trunk, and buy the generic for about $30 shipped.
