You're right. The "Scheckter Chicane" was new for 1975.

I agree it should be looked at in two parts. It's also a great perspective for all of us to consider. Sure most of us would have avoided #1 in this example but if found in a similar situation you have to ask yourself how well prepared are you for #2.

Those that grew up in the snow belt have an edge here. Most of those car control skills translate well to the track. As do the "give it gas to save your ***" mantra from the dirt biking world.

Lastly I would never have reached for the dash like that. I would have crossed my arms and bent my knees. The instructor is a lucky SOB. That move could have done some real damage!

I've never heard of this

This is why you left foot tap your brakes in between corners. First and foremost it eliminates pad knockback which is often mistaken as brake failure. Secondly if you tap your brakes on the straights and the pedal goes to the floor you know you have no brakes way sooner than if you wait until your actual brake point to discover that you’ve got no brakes

Annnddd probably most of your clients as well. I do it consistent enough that I've been told my brake lights are intermittent and need attention about once every 3-4 weekends.

I know it's probably a car show or special event, but does it look doushey to anybody else his car is pictured parked in a handicap spot in the linked articles? It just furthers the stereotype.

From reading through the r3vlimited thread apparently the car had a modified/replaced master cylinder as part of the S52 swap. For those not familiar with BMWs, the S52 is the stock motor in an E36 M3. This guy's car was an E30, a generation older. So he swapped more than just the power train.

It wouldn't surprise me if something failed within the modified parts. One thing nice about stock is you stand on the shoulders of the product testing and engineering of the manufacturer. When things get modded, some or all of that is out the window and the likelihood of a failure increases even if the mod is done well.

Yep, right around 2:15 he gives 3 left foot taps before he needs them and right foot brakes... This is something I need to work on being more consistent with. One more thing that should be committed to muscle memory.

"Thirty minutes into the session without any warning the brakes were gone and I had no pedal pressure as I entered the braking zone into turn 8."

Boiled brake fluid? WG can be tough on brakes.

I recently had a student with a heavily modded WRX, 450 hp, stripped out, full cage, harnesses, coilovers, track pads - and street brake fluid.

I do that left foot double tap as well. After an instance at Summit Point years ago in my dads car. Braked for turn one pedal went soft (car was getting double duty in August). Pumped it while coming down through the gears while keeping the car straight as long as I could and took the corner around the outside. Since then, I always give the brake pedal a light tap before I get to the end of a long straight.

As far as the incident in question, sounded to me like he pushed and held the clutch in and disengaged the drive train. Did that ONCE at my first DE. Instructor smacked my thigh (1997 so not everyone had a communicator) and told me always keep the drive train working for you and never coast and the only time the clutch should be in is during a gear change, or if it's a both feet in moment.

Almost every pro I know does this (tap-tap).
