I tried to search but you can't use DX or SI in the search. So finding a topic w/ them in it is a BI@tch. I had no luck searching.

I'm not sure which will suit me better a DX tranny or an Si tranny? I know i've read about both being a great choice and the differences at one point in time, but can't find the D@mn info again!
So i'm now posting and looking for input.
which to use? DX or Si
Oh, and yes it will see track time, i preffer autoX or road race over Drag, but i want to find the one that works for both, if thats possible?
