Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi All, as part of getting my suspension to m030 spec I'm fitting the appropriate anti roll bars. I understand that the standard front ARB for the 986 Boxster S is the same part as the m030 anti roll bar. This appears to be confirmed by the part diagrams also. These are widely available on Ebay so I've got hold of one. However, having measured them both with my calipers I've found the following: 'M030' front ARB - 23.9mm (24mm?) Standard front ARB - 23.5mm (23.5mm?) This seems like a pretty minor difference - possibly within the margin of error. Does anyone know if these numbers are indeed correct? Any assistance much appreciated.

POST 2Original post

Following with interest, as the invoice for fitting The M030 on mine doesn't mention roll bars.

POST 3Original post

I measured my m030 front arb as 23.6mm last year. I also found out it had 3.5mm thick walls, so perhaps that the major difference over standard?

This is a source reference. Confirm exact model applicability in the original material.
