1971 240Z autocross class

[Zedyone_kenobi]

Stock everything but with tokiko springs and struts...

What class would I be in? Running All season rubber, so no race tires.

[Zealous]

Depends on the sanctioning body.

Check out the solo rules at SCCA:

I am not an expert but I was actually looking into this myself the other night as I would start out as a novice. I think what might push you out of the stock class are:

• Bushings (if non oem rubber)
  
• Springs
  
• Tyres (sizes matter here)
  
• Your shocks are ok according to the rules for stock
  

These would push you into street touring or street prepared depending on the tyre lists and springs. Not sure what you are running.

Let me know what you find out as I am interested in running autocross this year too.

Well I have run nothing but subarus for a while, but really want to give RWD in an autocross a try. The Z seemed very fun to drive during track days, but the lack of power gave it a disadvantage. However, autocross is all about being nimble, and responsive.

I am running 195/60/15's, potenza UHP all season rubber, but those tires are living on borrowed time. I just found a sight that sells DOT approved race tires in 205/50/15's for 125 each. I paid more for my all seasons!

Now I have no intention on trying to be seriously competitive with this car, I just want to be properly classed.

[5150 will]

Depending where you run might depend on where they class you. They may let you run in the stock class but I would believe that the springs and 15" wheels put you somewhere else. If you want to just go out and have fun who really cares anyway right? I find that if you have "obvious" mods you will be classed appropriately. If you appear mostly stock they'll probably put you in stock unless you kick some "regulars" butt who complains

[gnosez]

Focus less on what class you will run in and more on car prep. Seat time is what you're looking to get and the more the better. Worry about class when you can run the course balls out and not go off course or hit any cones.

Bottom line: just go out and have fun.

[Zedyone_kenobi]

I was more worried about what 5150 above and the regulars. I have been competitive for a few years when I was autocrossing, but again, that was only in a 2006 WRX STI that was mildly modded. Hitting cones was never really a problem, but it took me 2 years to learn to drive the STI fast. The Z will not be entering any regular racing, but I think it is good to go out and race them from time to time to keep them honest so they do not get use to being a garage queen.

THanks for your answers, I will get a hold of my local chapter to see where they want to put me. Like you said Gnosez, I really do not care about the times so much as I want to have some fun sliding the Z around.

I tracked my yellow '71 for about 7 years. The best tires I have found, without going to full race slicks like Hoosiers, is the Toyo RA1. They have great grip and the last a really long time on a Z.
