I have a nice little stock 74 914 2.0 that is my daily driver. Like I have mentioned many times before, I put about 15,000 miles a year of daily driving on her.

I have never AX'ed my 914, and I was wondering, how much stress does AX'ing put on your 914. And where are the main points of stress? I would imagine the transmission and rear CV joints would feel a lot of stress, along with the front suspension? And maybe some major tire scuffing?

So if I decided to casually AX, how much downtime should I expect to encounter? I would love to occasionally enter an AX just to learn more about my car, but at what expense and level of downtime would I encounter?

And how much wear would I place on my transmission/CV joints/suspension/etc???

My thanks.

Eric,
Get autox tires first off.
You will wear out a set of street tires in one season.

Tranny.
You will miss shift. Its called the money shift...you clip reverse on your way to second. Learn how to shift quickly, yet not miata quickly...
If you can do that, your tranny will be fine.
I do change tranny fluid once per year and check the magentic drain plug to see how much metal is on there.

For me, with three people driving my car...my syncros and sliders lasted 6 years with no issues...I just redid the tranny.
It still shifted fine, but after taking it apart and looking closely...it was due. The bearing in the intermediate plate will also die eventually, but none of this is a big deal, just par for the course.
If your tranny was new from the factory I would guess 10 years of autox would be about the limit...
It just puts more strain on the tranny.

CV joints...they hold up fine as long as they are ok now...its just like any car...you will hear them first...just replace them immediately because an autox will make them go from bad to dead in one day...un like normal easy driving.

Everything else is just normal wear and tear...brake pads get used up faster.

Then, as JP and many many others know all to well, you will get addicted and eventually upgrade everthing in the suspension, brakes, and finally cut off your roof and put in a full cage and a six cylinder motor and huge fender flares...and and and
