Driving home from work, two elk walked out in front of me. They freeze when they see cars (Darwin at work).

I was only at about 45mph and heading up hill so I could stop. Often, however, I would be going much faster.

The A3 brakes seemed pretty mushy although they worked and the ABS did not kick in. So I was not at the limit. I beleive that part of the problem is the car is so heavy.

Any simple mods to increase performance? Pads? Lines? I am not ready to invest thousands.

If the ABS didn't kick in then you still have braking power left. Tires are the #1 influence on braking performance. Next pads, then fluid and rotors. BBKs are more bling than anything else, especially for a single panic stop.

Good rubber will make far more of an impact on that one stop that any BBK. When I upgraded the tires on my auto-x toy from crappy stock tires to Falken Azenis the braking improvement was amazing.

x2 BBK are primarily for preventing fade during repeated high speed stops.

for street driving. Obviously they're going to be better for fade on the track, but I've seen a few tests done where the #'s show that the BBK takes the car an extra couple of feet to stop compared to stock brakes. It would be interesting to see comparisons of 60-0's with different tires/pads etc alone.
IMO BBK's should only be purchased for for 2 things...Looks or if you track the car. I've never seen any evidence that for street driving they have any advantage.

This is a really good clip on the difference tires can make in the wet.<ul><li><a href="http://www.tirerack.com/a.jsp?a=AZ4&amp;url=/tires/tiretech/techpage.jsp&amp;techid=154">http://www.tirerack.com/a.jsp?a=AZ4&amp;url=/tires/tiretech/techpage.jsp&amp;techid=154</a</li></ul>

Thanks! Everybody should watch that video.

or he isnt mashing the pedal. skip to the pads if your abs starts kicking in all the time get some stickey rubber

I'm sure it wouldn't be nearly as bad in dry or without standing water...good info tho.

For an autocross I went one time, I felt like the car could barely stop intime for the stopbox.

I've upgraded pads, fluid and put in stainless lines...pedal feel is still mushy with alot of travel.

There was a guy with an S8 that made a brace for the master cylinder, I wonder if it was for similar reasons of crap pedal feel.

The thing about our cars is the master cylinder is hidden in a rather low part of the engine bay by the driver side..
