So.... Larni and Shay were in the paper this week, for those that didn't see it.
The club has a wide range of drivers and cars and welcomes all interested people to join. We run a variety of events and have roles for drivers, event organisers, scrutineers, timing officials, marshals and spectators.
The culture of the club is relaxed and friendly and we encourage new members.
MotorsportNZ sent this through to scrutineers, but it would be worth checking with a dealer if you have one.
We have received information from LEATT® about their MRX Head and Neck Restraint System which details potential problems with the device. The company states the following:
"Leatt Corporation's quality assurance procedures identified a materials flaw in our Head and Neck Restraint System (MRX) used exclusively in motor racing. The device can crack unexpectedly."
'Unexpected cracks' are probably not a good thing! So as ask that you keep this in mind when performing safety audits and are looking at 'frontal head restraints'. We don't believe this make of FHR is as common as other well-known brands although marketed and sold here in NZ. If you do come across any of these safety systems the best approach will be to advise the owner about the recall and follow Leatt's advice as follows;
"STOP using your MRX device and contact your point of purchase to return your MRX device for a replacement, refund or credit."
We understand the NZ dealers are well aware of this recall by Leatt and will be happy to assist their customers as necessary.
There seems to be an increasing trend for competitors to arrive at an event with incompatible tyre / wheel-rim combinations. Schedule A doesn’t cover this in any specific detail and perhaps it is sometimes difficult to determine if a car should be allowed to run in a certain configuration. The picture to the right is probably a ‘no-brainer’ and shouldn’t be accepted. Some other examples might not be so clear cut though so how would you determine if a tyre / wheel combination was acceptable ?
Tyre manufacturers design tyres to be used within a small range of rim sizes. As a general rule the sidewall of the tyre should be close to a 90 degree tangent to the rim bead for safe operation and optimum performance. There is a good table available on the LVVTA website showing recommended tyre to rim size data and if you suspect this may be a problem at an event you are officiating at it might be worthwhile printing a copy out for your reference. There are a number of other websites also that provide this advisory data. You could consider most of this to be industry best practise and a useful guideline when checking at an event.
Sometimes, if it just doesn't look right, then perhaps it’s not.
