What also helps heel and toe is having the thottle pedal further away, and the brake pedal closer (towards you), so when you look from the side you can see a difference of at least 1 cm between the pedals. I modded my g25 pedals like this and I'm only 2 tenths slower then my pb (which I did with the sequential setup).
The only problem I have is the speed of my downshifts, so most of the time I'm downshifting more then 1 gear (like going from 6th to 4th). Threshold breaking is also a big problem

You are exactly correct. The idea is that when you have pressed the brake, the go and stop pedal will be on the same plane. That is the ideal. In reality, the gas should be slightly lower, just to make sure that you can slide your foot over if you have worn the brake pads or otherwise caused the brake pedal to overtravel.

I thought they tapped the brakes to make sure they still worked, which would especially make sense for the 24 hour races... But on the whole heel toe thing I have heard of either bending the brake closer to the throttle or to like install metal petals with slightly wider surfaces...notice I have only heard of this for regular cars not sure how it would work with the G25

I also do the brake check. I should get over it because by the time I realize that I have no brakes, the car will be quickly approaching my usual braking point. Just enough time to wave goodbye to the corner workers as I flash past.

Adding pedal pads should be fine on a G25 as long as there is enough support in the pedal hinge to take the offset load. I say this having not seen the setup in person. Anyway, the same issue is true for adding pads to a street car. You could always add a button to the shifter to provide a throttle blip. People have adapted this to actual racecars, so I would allow it.

It is important to analyze your mistakes. That is how you, a) name the mistake, and b) find a solution.

That turn is actually a lot faster than you would think. All you really need is a little brake just to settle the car, then back into throttle. There is a good deal more exit room than you would think because it is somewhat blind. I would say that he was right on the edge of traction, then back off the throttle a hair.

Someone spins there at every track day that I have been to. The one thing I don't see, though is an instructor. I'm not sure if this guy is ready yet to go solo.

VIR is an awesome track. Lots of elevation change, two long straights, big turns, small turns. The portion of track that this fellow started his vid from is known as the climbing esses. Takes lots of rythem and balls of steel to drive near wide open throttle.

VIR should be in S3!

The Handbook is actually being used as a textbook for a class I am taking. I use that thing on a daily basis at work, too.

It will also depend on whether you are cutting your own threads versus buying a threaded rod that has rolled threads. As has been mentioned, the threads themselves cause stress risers at every corner that is formed. A rolled thread reduces this as they will be radiused and work hardened.

For your situation, the rod will stretch to some extend. If the stretch is too great, the pitch of the thread will be too great for the nut. This would cause the nut to bind on the rod. If you plan on putting a tensile load on a thread, check out the ACME thread form.

It sounds like you don't have a copy of "Machinery's Handbook". In America, it is considered the engineers Bible. It is currently in its 27th or 28th printing.

I am wheel to wheel licenced in the Midwest Sports Car Council, which is an affiliate of the SCCA. I have raced at Blackhawk Farms in Rockton Illinois and Gingerman which is in Michigan, plus autocrossing at various kart tracks parking lots. Havent raced for 5 years now, used to race a 1984 Fiero.

I ran Blackhawk Farms back in 2002. That was my first on track experience since racing quarter midgets when I was a kid.

I just got done racing Blackwood RallyX on a demo server. Loads of fun. Especially since my roomate does not have an S2 license.

Since I got my license, I have lost my ability to drive the XFG on pavement.

The YouTube video is from my favorite track to drive. Top notch facility. This vid is not of my car, but I wish it was.

It seems to me that H-shifters are found as expensive add-ons, or as a part of high dollar rigs. You could always wake your own.

A quick search turned up this: http://www.frex.com/gp/shifter/index.htm

If I were to make one, it would be a good bit simpler. The one in the link actually emulated the function of the shift rod as it would raise and lower the forks inside the gearbox. As much as I like the realism, it would be to expensive for me.

Mine would be a set of six switches, one at the backs of each gate. A pair of ball detents to simulate the meshing of synchros. A pair of extension springs to center the handle.

Feel free to steal my idea. :icon23:

I used to be pretty heavy into touring cars. Raced asphalt in the summers and carpet during the cold months.

My first was a TC3 racer which I upgraded quite a bit to lose weight and stiffen the chassis.

Later I moved up to the Factory team and transferred whatever mods that made sense. That car felt much more substantial than the previous, but because of the mileage on the old Racer model, it felt like it rolled smoother. My track always ran stock motors, but I would keep a 13 turn in my backup car so that I could have fun in practice sessions.

I abandoned the hobby when I wan old enough to take my real car to the track.

Quick stats:
1993 Ford Taurus SHO
3.2L DOHC V6
220HP 215LBFT stock (Engine should be making 260-270hp at this point)
Weighed 3400 pounds with the original automatic transaxle and full interior. Should be closer to 2900 by now.

Betcha didn't expect to see a four door in those shots, did you? BTW, there will be a roll bar in the car by next summer.

Thanks for the interest,
Mike

I guess I could make this my first post on the forum.

I do a few track events each summer. Looking forward to running Watkins Glen next summer, as well as Virginia International, and Summit Point.

I might be the only person here whose race car is also their daily driver. Fully stripped, yet still street legal.
