I'm guessing that you have upgraded to a slick tyre also for this upcoming event? If so what size running etc.

In brief, simple answer is sleeve NC sensor into the bigger RX8 upright sensor hole, drill out sensor bracket hole for mounting sensor from 10mm to 12mm. As long as normal NC 'ice mode' issues with big tires don't bother you, that's it. This is the choice we are making here.
Option two for better ABS calibration for big tires (less ice mode) is convert entire car to RX8 ABS. Get ABS computer from base model junkyard RX8 without traction control, add matching front 04-08 RX8 hubs, rear RX8 bits as we have done here, and then you have complete RX8 ABS using the rear RX8 sensors we already have here, but you lose speedometer without some additional work.
Brian wrote:I have never had issue with ice mode, so we went with MX5 sensors. You can convert to RX8 sensors but as explained earlier you need ABS computer from RX8 and RX8 compatible sensors front and rear. Front RX8 hubs on this car from 09+ mean we already have RX8 compatible sensors at the front, they are interchangeable at the front. But at the rear the MX5 ABS computer wants MX5 sensors, so that's what we did. We were going to make a sleeve for snug fit but ran out of time, just drilled out the bracket hole and installed and they are working normal.
