The power steering rule would be a tricky one. The Miata rule doesn't work. Miatas came with or without power steering.

The advantage for Miatas (NAs, at least) is that the PS rack is quicker than the stock manual rack. By depowering the PS rack, you lose the parasitic drag and weight of the PS components and get to keep the faster steering.

all these crazy combinations and yet still no non-USDM motor allowed...

What response did you get when you wrote to the CRB and to your BoD rep to express your displeasure with that ruling? Could you send me a copy of that response?

While that is true of most power steering racks vs. their manual counterparts, the question I have is "so?"


really - does it matter? is there REALLY an inherent advantage to faster steering? I'm sure some manual racks have so much mechanical advantage as to be a chore to use on the track, but I've never heard anyone complain about it on a miata or otherwise. hell, some people see power steering as having an advantage over manual in the first place, and would argue that removing it does nothing but slow you down from fatigue.

Steve and I have the same BoD rep, Robin Langlotz, who seemed to think it was a CRB issue but was supportive of per-engine allowance when we discussed it with him. he also voted against all this SFI HNR nonsense. we're happy with him :happy204:

I have tried power and manual, quicker and slower racks and would take quick powersteering rack ANY day!! I felt I could react faster when the back end stepped out. Although I have found that with the manual rack I use less multiple steering inputs (less sawing). My problem was I was blowing up powersteering pumps and throwing the accessory belt.

but that's just me. :)
