Well just got the MRT splitter installed...Much shorter than the Laguna Seca Splitter and also the World Challenge splitter...In fact it's the same size as the stock boss splitter (see pix below). Originally was trying to get the world challenge splitter but no place could ship to Maui.. Unbelievable.. Anyway got mine at sliver horse racing for a good shipping price. MRT of course sells it for a great price... I'm not to sure if it functionally makes a difference since it's the same size as the stock splitter, but I like the look with the spindles.. It's a straight install, just remove the bottom stock splitter and the new splitter goes on through push pins... Not planning to really track the car so I think I'll be ok. Though I've been told by MRT, the splitter has done fine at the track with just push pins...
