Hi All,

Newbie here. Recently bought a 1995 Miata with 302 Ford Swap. I have been crawling around the car a bit to get acquainted, haha.

One question I have is Aluminum vs Steel driveshaft. From racing in my past and many people in their street rods, Aluminum is a given for the performance boost at low cost and high reliability. When under the car I was slightly shocked that the car has a steel driveshaft. Does anyone here have an opinion/experience on one side or the other as to what they run and why?

Appreciate anyone taking the time to read and reply.

I am running a steel driveshaft because that is what used to come included with the "kit" back in the day.

 

That is what I have in mine, confirmed with a quick magnet test. When poking around I noticed that it still has a mfg sticker on it, somewhere in Oceanside California I think? Would maybe have been bought from Monster Miata when the guy who originally built the car bought a swap kit. I was thinking about swapping out for Aluminum version, as an upgrade. Could fabricate locally but wondering if the ones Monster Miata sell now are Aluminum or Steel. Doesn't specify on website. Looking around last night as I sort through some maintenance issues, I think I'm in the market for a CV axel shaft. Have to confirm if the play is in the cv joint or bearing still.
