Autocrossing an '84 325e

Definitely change your motor mounts. Otherwise a nice 3.91 diff, a chip and seat time.

At what speed does 2nd top out with the 3.91?

this may help w/ the MPH question:

Well, bad luck hit today. The caliper/full bleed today was what the master cylinder needed to shit its guts today. Got an internal bypass, new cylinder should arrive tomorrow morning at the shop and it gets installed. So much for free spending money this week! All in all, I'm glad it failed at the shop on a test drive instead of on the street or track.

Amen on the motor mounts and chip, but IMO a 3.91 gear is way too high for an eta. You'll be shifting into 3rd on fast courses, and the engine just doesn't rev high enough to utilize the gear. Better off with 3.25 or 3.46 max.

just drive the dang thing. all you need for autox is a good battery tie down, seat belts, a good throttle return, tires that aren't bald and gas.

Have fun!!

Autocross = complete

Things went mostly ok, shaved off 4 seconds between first and last runs. I have work to do in the corners, lots, but straight line speed is killing me. The 4 straights on the course are losing me about 3 seconds according to the instructors/experienced guys here so I may jump on a chip in the next few weeks. Aside from that the car is fine, just need to practice my lines and brake markers better
