High temp Castrol REACT brake fluid and after 4 events added new front pads and new front rotors. Total cost $3460. Have used up 60% of tires. Plus 5 oil changes and two brake fluid changes. Not a cheap sport even on a low budget like mine. Oh add another $3500-$4500 for track fees, hotels, fuel, food etc. Oh add if you don't have a pickup someone can drive to the track with tools, tires, Jack etc. You'll need a friend to drive it and follow you to the track. It's definitely a commitment. And I didn't brake anything or spin or crash. But OMG I love it and I'm 3 years away from 70 years old! -

^^^^^^ This is why this thread is great I'm 56 and a beginner LOL

still reading through the post but thought id throw something in I learned from a guy that used to race Le Mans

He had me run the course for a few laps with no brakes. this made me really plan ahead and wow did it teach me how to pick a line. driving with no brakes makes you take the path of least resistance and that's the smoothest (only do this on an open empty track or where its safe)

after this when I came back full speed my times got significantly better and I could tell it was a lot easier on the car. much more natural feeling

also, somebody earlier touched on this, but try and learn to not coast through the corners. Another thing this guy taught me. try and stay on the throttle a little through a corner) under acceleration you move the CG farther to the rear of the car. this puts more pressure on the rear tires giving more traction helping to prevent the rear coming out in front of you in a hard corner. kinda hard to get used to at first

Wow, I have been autocrossing for a while now. I used to drive an 89' M3 then a Miata and last time it was Subaru STI then a Mitsubishi Evo RS most recent is my 135i.

I recently bought an 04 Z06 with 7.5K miles, it is completely stock. I ran it at the last autocross and it was very nice and powerful but I was sliding all over the place. The car still has the original tires and I think they are shot.

So my question is I plan to do a square set-up with the stock 18 x10.5 wheels for the rear and have them also in the front or do I just keep the stock set-up and just buy better rubber?What is the best tire and tire size someone has used for these widths (10.5 and stock) without rubbing on the fenders? Keeping in mind this is on Guam and there are really not enough participants to have different classes at this point.

What alignment numbers do most use for autocrossing? max neg camber front? rear?

Earlier someone mentioned "Martial Arts shoes" as a good choice for footwear. I'll agree. I have found wrestling / mat shoes work well. $35 for a pair of Asics with a thin, grippy rubber sole, and are perfect for heel & toe driving.

Basics in road racing.

The Physics of racing; a great series of articles. Includes cool stuff like slip (grip) angle

The turn fast link isn't there, but the physics of racing is a lot of great info. Getting car ready for first hpde class. Trying to learn as much as I can before I go. Great to see so many people share info and lessons learned ( saving us newbies a lot of time, money, and frustration) for love of cars and sport.

question about ron fellows driving school in spring mountain for new owners, is it possible to learn most of the stuff from youtube, forum, etc? the level 1 and level 2 classes.

I am thinking you can but the school is geared more toward vette and will explain things specifically about vette, like electronic aides etc? Just got a new vette and wondering if I want to go or save few bucks by other methods like youtube, forum, etc.

Haven't made it all the way through this thread yet, just found it, but I appreciate all the info. Going to try my first ever autocross tomorrow in my new C6. Been driving pickups & motorcycles since I learned of this sport/hobby/habit.

Thanks for all the posts!
