Mr eobe here
, see Jon, I told I get called lots of things
Anyway, with sensible hat back on. I still have an NC rack in the garage and found like you, it would not fit.
As Jon say's search the race car thread as details are in there. Once I sussed out how the RX-8 rack worked it was an easy conversion and just a matter of making a sleeve to stop the worm drive working.
Coils, if you remember I was running stock RX-8 coils and my mapper of the time kept saying that the coils were why it would not map properly---------wrong, the AEM coils made no difference !!!
So it may save you money to run the RX-8 coils. Also Pip and myself uncovered something weird when he took over. I was using the full function wheel but also took an RX 8 wheel, an FD wheel and a wheel I had modified. we ran the car up with different wheels attached and bizarrely it made no difference, yet again know this may save you money.
