I don't believe you can use 75mm studs with 12mm spacers. At least I couldn't safely do so. So I changed from 75mm to 93mm.

I did not look up the price differences but if you do this conversion you are a track rat and you already know how much 200tw or slicks cost and how long they last. In addition, if you constantly put wheels on and off and torque the studs before and after track day then you might as well do that on M14 studs.
Core4 states that you can run a 12mm spacer on the 75mm length, and a 20mm spacer on the 93mm length, which is concurrent with what other companies who offer stud conversions claim. Not really sure what you were getting at by mentioning the expense of tires.

Never mind about the tires.
The 75mm did not work for me with 10 and 12mm spacers. I did not feel there was enough thread left.

This was my personal choice.

This is 93 on a wheel that does not use a spacer. The biggest difference between the 93 and the 75 is that the 93mm has a long end with no thread. This makes it easier with mounting the tires and not damaging the thread

Thanks for sharing these photos Rhyary, I kind of see what you mean with the length. Just to confirm, you're using the Core4 14mm studs, 93mm length? I'm planning on purchasing the same once my car sees real track time.

Here are mine, 94mm length 14mm MSI studs on F80 hubs from Core4. Tom gills is awesome to work with.

I am. What I post is typically from personal experience including this topic.

Those M valvestems shave off 8 grams!
