Streetable Aero for your X

[4B11T]

As per the thread title I'm looking at adding some streetable aero modifications to benefit track use for time trial type events for street cars. Keeping it simple looking at a 4" front splitter, any effective rear wing ie: aeromotions / voltex type 5, maybe also build an aluminium flat floor & rear venturi if we really get keen. Aero really seems to be a real balancing act so was looking for some advice & actual experience on this for some pointers. I have trawled the net picking up lots of information but may have overloaded now & confused the crap out of myself. Ideas or internet links to helpful sites or articles would be hugely appreciated.

In theory, any aero should be streetable as long as the ride height isn't too low or the splitter isn't too massive. It sounds like you're on the right track with a 4 inch splitter. With 4 inches, it's unlikely you'll need a dual element wing. I would honestly do your underbody first (with splitter) then test things out on the stock wing. An aeromotions or AJ hartman wing would be a good wing choice and you'll end up running it at low-ish angle of attack on a 4 inch splitter, depending on if your rear diffuser is aggressive or not.
