Be aware that what you choose to do depends on what organization(s) you decide to autocross with. Also understand that the class rules may differ from region to region with some national organizations.

For example, if you choose to autocross with PCA you need to check the class rules at the regional, zone and national level. In my region (NER Northeast), you have street classes that require that you don't modify anything that may affect performance. This includes adjustable coilovers, camber plates, any engine modification between the throttle body and exhaust manifold, both included, etc. etc. Then there is the modified class where you can make those change. For these two you cannot use tires with under 200 tread wear, which the RE71-R complies with. And finally there is the class where you drive on R rated tires.

Understand that the non-street classes is where the big boys drive. You will be crushed!

So, here's my advice: Read the rules, drive in street class until you are one of the top drivers. It is less expensive and more fun. Once you have the experience and the $, go for it in the other classes.
