Stagea99

I've recently moved from QLD to NSW and to pass the blue slip requires an engineers certificate for my BC BR coilovers. Apart from the legal ride height is there any reason why they shouldn't pass and does $400 sound fair for the certicate? Car is 99 Stagea RS4. Also will not being ADR approved be a problem?

For my 100,000km service i decided to fit all genuine Nissan parts. Can anyone explain why a genuine Nissan oil filter (part No. 15208-53JOA) is only half the size of an aftermarket Ryco (Z145A)? Can't help but think the larger aftermarket filters would perform better than the tiny Nissan filter. Anyone got any tips on how to change the oil filter without spilling oil everywhere? I usually try making a pool with paper towel and stick it under the filter while i screw it off but still always manage to make a mess.
