MOT and the RX-8.

Post by Delanor » Sun Apr 28, 2013 11:40 am

Be aware! When presenting an RX-8 for an MOT you should inform the tester that the cars is equipped with a LSD as it has now become apparent that some MOT stations are not aware that the car is so equipped (although that information should be available when the cars details are entered into the system) and as such the usual brake test using rollers should not be carried out as damage can occur to the differential there is an option to carry out the brake test with a decelerometer which will not damage the differential.
If making a purchase from a dealer it may be prudent to mention this as checks could then be carried out but with a private sale it may prove difficult to establish other than if the test drive proves satisfactory.

Specifically it's the testing of the rear brake bias that's the issue with rollers, since this involves locking one rear wheel while the other is turning.

Some garages may not have deccelerometer equipment and it's use does require a road test.

Performing the tests with rollers but skipping the rear brake bias element should be safe - it's what my local tester does for LSD-equipped cars.

Note that MOT's in Northern Ireland are performed by the Driver & Vehicle Agency, who are convinced "that their state-of-the-art equipment is safe for use on all vehicles"; which is strange since the same laws of physics still apply. #-o [-X
