http://www.gtechpro.com/rr.html Is the one I have. Sorry I forgot where I got it though. I can be calibrated for 1/4 mile although I havent yet. Because lack of a drag strip, but it does work well to see increases from mods. I like the software also because you can see if you consistantly pulled the same Gs on each turn and time etc.

 

You hardly get any body roll. I bet my car looks similar under hard cornering with my IntraX on. OP said his Intrax took the corners a little better than the Eibachs.

Still need a gosh darn alignment but there's no point in spending money on an alignment until my black Sokudo 8's come in because that'll f*** up the alignment all over again.
