I have no idea what people mean when they say i have a AC short shifter kit?

fast accel?

and what are the mechnical details of it?

and $?

thnx.

It affords a shorter shift, hence the name.
Changes mechanical advantage.
Shorter the throw, the more effort needed to move shift lever.
So you can weight the shift rod or get a heavier knob.

AC is about $800. UUC $295 IIRC.

AA depending on the stage: $100-$250

I think Rogue Eng is around the same price range.

AC is obviously the priciest. Nice looking, but personally don't think it's worth the $$.

The purpose of a SSK is a faster shift. Period. And that is what they do.

Short shifters increase the effort required to shift. The pricier kits reduce shifting effort.

Replacing all the non-metal components on a stock shifter is an inexpensive alternative to a SSK. It will reduce the slop of an older shifter.

I'm in the market for a used E36 M3 and just yesterday I test drove a 1995 Avus Blue OBD I with an AC Schnitzer short shifter kit and it felt absolutely amazing. Each gear change was attained by moving the shifter about half an inch in each gear change direction. Going back to my 1998 328i's transmission was like going back to driving a bus or something...it was that phenominal...coupled with its 275 horsepower and H & R suspension with Bilstien shocks. I was in heaven! :D

There's also the Ron Stygar kit, which I think is the cheapest of them all.

Here's an article that describes short shifting, with a bias towards R.S.

I have no affiliation with Stygar. In fact, I have a UUC kit (because I got a used one for cheap).

so it doesn't change redline?

i redline at 4500, thus i have to shift already fast enough...if anything i want a high redline (like an s2000 :D )..but the SSK just changes the placement of the gears?

I'm also cnofused on y a person would want to make it more of an effort to shift gears.

it's not the increased effort you want, that's a side effect because of the physics involved. what you're trying to attain with a short shifter kit (ssk) is the smaller amount of movement that must be done in order to change gears. check out the websites of ssk manufacturers. uuc, rogue engineering, active autowerkes to name a few. also go to http://www.unofficialbmw.com/ronstygar.html and check out the drivetrain section. lots of info there that might help you along.

Splitting hairs. A shorter shift results in a faster shift.

D=rt; so, t=D/r if r(speed of shift) constant then t decreases as D decreases.
Shift takes less time. QED:confused:
