I was told the stud kit is like pinning the motor. I was wondering who has the best price on this kit.

 

Well, it's similar, but it's not the same: http://www.mazdatrix.com/studkit.htm

 

that was oversize no drilling was needed and you can use the stock flywheel on the 2 rotor for the 3 rotor you have to drill and can not use stock Flywheel.
I think its was an AUSSI company I will look around and ask a few more ppl...

 

It's the same studs, Mazdatrix just resells them. They are from the Aussie company X-Treme Rotaries:

I ordered my studs from them before places here in the US started carrying them.

 

I've never really seen the need for these on a street car.......why did you choose them Kyle? I've installed them on a few customers motors at their request. Seems like a well-made product.

 

Since my car is mainly for the track, I wanted some extra protection as the motor will spend most of its time in the upper rpms when running. I have to say, they are a pain in the rear when/if you have to disassemble the motor.
