They still do. They have their own class in SCCA, they're fun to watch, especially when they finally go beyond their ability to catch a slide at 60 mph, which is quite easy.

But seriously, OP's course blows. I'd rather spend my money on a single speed kart, and, you know, just go kart racing. W2W karts that only go 45mph would be way more fun than autoxing that, assuming a club exists to run with.

^^ Agreed. Either run what you have to learn how to drive YOUR car better, upgrade your car to make YOU happy on the roads YOU drive everyday and learn to drive that, or spend your money on a kart and learn the principals of driving fast with the best platform for that specific venue.

I drive with Windy City Miata Club in the suburbs of Chicago and we have a parking lot that we autocross on that is notoriously technical but I spend most of my event in 2nd, sometimes third gear.

Did not know. That's even better.

Yea 1st gear autocross is not so much fun. Steering inputs on a course that requires you to go that slow just get ridiculous and harsh and the wonderful feeling of controlling and dancing with vehicle dynamics and tire slip angles just goes out the window.

You will not have a difficult time spooling your turbo in 2nd on that course unless you're driving like your sister's friend's dead grandmother.

Does this count as suspension?

Whatever it is, I'm fascinated with it.
Love looking at crazy suspension setups.

Looks like it allows for about a quarter inch of travel though? tops

I'd say, but I'm no official.

And as others said, it looks like a drag car..

It'd probably look a little something like the red line, blue line, or yellow line. Not sure which.

Here's the thing.

I've seen people who have considerably less resources successfully turbo their car.

I've seen people more clueless than you who successfully turbo their car (read: dropped they car off someplace with a blank check).

But from where you are right now, your combination of cluelessness and lack of resources does not look promising.

You really shouldn't be touching this thing right now. You need to do a lot more reading and learning first.

Then again, you'll likely only destroy this car about as much as I destroyed my Saab Turbo and Merkur (read: both ended up parted out by the next owner).

I use my Galaxy Note tablet for very important diagrams like the one shown above.

Nice, I hoped it was an mt.net original.
