I finally sucked it up and taught myself left foot braking over labor day weekend at Grattan. I went slower during the morning sessions and spun out with a duffed 4-2 downshift but now that I got it I won't ever go back 2thumbs.gif


I think you'll still be learning LFB a couple of years from now. I made the mistake of trying it during a race and decided that it helped in T1 at Sears Point. The problem was that I hadn't done it enough for it to be an automatic response to a braking situation, and in the heat of battle a few laps later I got confused and couldn't find the brake pedal into T2 - terribly frustrating experience. Drove off the outside and into a tire wall, right foot still on the gas and left foot lost.

That was 10yrs ago, I've been LFB in the truck ever since. Felt awkward and jerky at first, but I persevered. Once I could modulate braking with the left the same as the right, I practiced handing off the braking from one foot to another during braking zones, without changing the decel rate at all. It took years before it got ingrained into my brain and I'll use the left foot automatically in panic situations.

Haven't had the balls to try it again on track, tho.

The car is owned by my wife, Misty White from Texas. I'm logged in with her id to answer. I also race it when my ST1 mustang is under the knife.

Car is a 1999 SS that she purchased new and was formally an American Iron car that has morphed into an ST1 or ST2 car depending on which driver is in the car.

It is basically a cam only, 241 headed LS6 making 427/403 to the wheels, converted to speed density with Fast LSX 92mm intake, about 3200# running on 315/35/17 BFG R1's all around. DR. Gas oval tubing X pipe with no mufflers (sounds like a demon). Wheels are 17x11 from Jongbloed. UMI K-member and homebuilt watts link. Color is accurate FM3 panther pink from a 1970 Chrysler. Thanks PPG! It's purple when in dark light, and bright pink in sunlight. Graphics are a faux carbon fiber. Front hubs are C5/6 Corvette Race hubs with custom adapters that retain ABS (no more hub issues at all). Car is getting on in years but has had a lot of development work done on it in the last 36 months which has netted over 4 seconds of lap time at TWS (home track). Car is an absolute animal and requires a lot of concentration and strength to drive...but is a freakin' blast to drive. Took 3rd at Hallett in ST1 against some serious machinery and I was ON THE NUMBERS as ST2 legal. Not bad against the vettes and tube frame cars!

Plans for the near future are a Jerico and upgraded 10 bolt to get rid of the lateral axle slop and pad knockback. Then maybe some cubes as the little 346 has 7 years of hell on it but just keeps on doing what it does because we take very good care of it.

Is that enough info?! LOL!

Thanks! I noticed that cars pace compared to tube frame cars and had to know more about it.

Let me interject a little more background about the author ...

Matt is a humble, yet precocious individual, well known in the local DFW Mustang circles simply as MFW.

My most vivd memory of Matt is him stuffing a trash barrel with the remnants of a nose cone that once hung on the front of his car all the while uttering variants of the universal word, many of which make me blush to this day. Hence the "F" in MFW.

Car looks good, Matt ... sounds good too.
Misty has done a great job ...

FULL STORY FROM THE WEEKEND:

AKA: OVERCOMING BROKEN CAR PART 1 AND PART 2 !!!


http://www.witchdoctormotorsports.com/ch236.htm




"We launch and I work hard to put a ton of heat into the brakes and tires on the pace lap. I bring us slow around the carousel and slowly raise speed to where I'm dead in the middle of the power in 2nd as the moment steals all of my consciousness. My left hand holds the 9 o'clock position on the wheel, my right hand is open with fingers wide as the palm is almost touching the ball of the shifter. My left foot still dragging the brakes as my right foot is balancing the throttle position to the corresponding power needed to slightly overcome the brakes as my eyes are intently focused on the starter. I don't hear Scratcher, and I don't hear the car next to me with the loud exhaust dumping right at me. I don't feel the shoulder straps pulled so tight that my HANS is shoved into my shoulders meaning that Scratcher and I are one and any impact or nuance no matter how severe or minute is transmitted to my body directly with no filter or masking. I don't smell, I don't feel the heat and there are only two things that occupy my brain at this instant. First, the focal point on the starter's right elbow and second the gentle command to slow down my heart rate. It isn't fast by any means...in fact it probably was only a few beats above my resting heart rate, but in this fleeting moment I need to be relaxed and while my physiology is in a loop issuing and reissuing a relax command...his elbow twitches. Before his wrist has even moved vertically, the brakes are released, the loud pedal is matted and my backside goes to full sensitivity for the potential wheelspin that does not occur meaning my severe tire warming antics were successful. Result: Pack is left behind."



Mark,
I've not had time to do rear camber yet and at this point I think I'm going to do a front roll center change (as well as taking out the sliver of anti-dive) and get that done first. But then, yes, next is to get the rear cambered a bit moar.

QUOTE
As I went into diamonds edge to brake heavily and then turn and start my way back towards the front straight, the car felt darty under the brakes and I was thinking that perhaps I'd gotten the rebound settings wonky and this was the result. No matter, I just needed one lap so I scooted up the back straight, went through the carousel and flew under the green flag flying at the starters stand to begin my qualifying. At the end of the front straight I got into the brakes a little bit early and I'm glad I did. The front end washed out and the tires locked way too easy, I unlocked them after a nice cloud of smoke and then got into the corner. Scratcher felt okay in the corner, but had difficulty going straight. I assumed I had uneven dampers, a faulty damper or a tire going down so I hustled the car that lap, laid down a decent 1:37 and pulled it into the paddock to check it out. Tires were okay, front dampers felt find when pushing down on the frame...and so I went to check the bearings and steering linkage next. Uh-oh.

Thanks guys, I was dumbstruck when I heard the spec7 and PTF cars were going to be in our group when they are usually with the miatas. This being a big fast track I actually thought they were joking.

But....oh well. We did a SPLIT start for Race1 and I caught traffic sooner....and I'll post that up in a few days. Crazy there too!

Cage is 1.5 x .120 DOM. Brace tube was 1.5 x .095 ERW. It was a complete failure by the time I found it. There was no rust in the break, so hard to tell how long it was failing. That setup was in the car for 5 seasons (~25 events). It broke using the gator teeth at Road America, which are extremely rough at the end. Blackhawk Farms put in gator teeth and that was the race weekend before RA. I'm guessing that the load spikes (load/unload over the teeth) did it in.

Replacement is 1.5" square x .250 wall. Ready to find the next weakest link.

Wow, this is a very interesting failure. Lots to discuss here! If someone wants to continue discussion, please break this into a new thread. I believe I could provide some great insight with a few phone calls and research. I'm an engineer at an aerospace company who does welding, I have access to our corporate weld engineer who is also the onsite race day Track welder for Indy and Kansas Motor Speedway.
