I agree that welding/pinning the standard ones is a 'good' solution, but these are (I think) 250 USD for a pair which seems to be a reasonable price compared with the standard or RS ones.
I'd take a set, had a large off in my 993 Cup RSR race car at Spa and definetly need them ! Please email me at whelanporsche@eircom.net and I'll arrange payment.
sorry - no emails came through and I couldn't find this message! CoG welded my ones up. If someone else wants them that's fine otherwise I'll take them for later.
