Sprocket Mount Upgrade

[Blair.Hosie]

We have seen a reliability issue with the original aluminum sprocket carrier, particularly on the drive by wire engine but not limited to it. A few of these failures have led to significant additional driveline component damage. Some of these failures certainly have been caused by the bolts in the carrier or sprocket coming loose which results in an impact loading on the drive keys.

As a result, and in an effort to increase reliability and reduce running costs we have redesigned the sprocket carrier moving to a steel design with larger clamping bolts.

For those who would like to make the switch to a higher strength mount new revised sprocket mounts can be purchased here

I already noticed this on our demo car during recent service. Are you upgrading the bolts? If yes, what spec? If yes can stronger bolts be purchased separately?

The Bolts have been changed from 6mm to 8mm Link https://raw-parts.com/https:/raw-parts.com/product/product-9/

Any thought on why particularly on the DBW?

The shifts are a little more of a hit. They’re just a bit harder; hard to describe, its a different feel. There is a bit more cut on upshifts.

@John H - I have seen some wear on my original sprocket mount too (Chassis #43). Some of it is my fault as I didn't keep the bolts tight (to specification), but it is a part I keep an eye on now...
