How necessary is the set screw in the rotor?

[willworkfore30s]

We've got a meet tomorrow and are caravaning a little over an hour there with a few other e30s. My problem is I just changed my drivers front wheel bearing and I don't have a set screw to go into the rotor. How big of a deal is it for me to run it for a day with no set screw and just lugs holding it in place?

I havent had them in quite a while and I am fine.

So is anyone running the RX7 upgrade, you will be fine. Just a little more of a pain to put on the calipers when the rotor moves around

It's just there to make it easy to line up wheel bolts. Not important at all

Awesome news guys I have a set screw in there now but its not oem and is not flush mounted so my spacers don't fit flush. Since i have ghey vw wheels the tires rub the struts with out the spacers.

But since the screw is in there now when I take it out the rotor stays in place. So I should be good.

Thanks for the quick answers

Get studs.

Doesn't matter though.

Will do. Only just got tags and a title on this car today. Been a long road trying to get it titled and legal. I have many mods plan, basically a restoration but it is my tinker car. It will be a slow process.

Throw em away and forget about em.... They have gotten rusted and stuck in so many of my e30s from POs neglect.
