I spoke to the mechanic today who will be doing the roadworthy and he said bolt on type of pedal covers would need to be bolted THROUGH the pedals, not bolted on using brackets as most aftermarket kits have, or alternatively, grip tape/skateboard deck tape is acceptable, as long as the pedal has a grippy surface it will pass. So I spent $5 at a bike shop on a 90mm x 500mm strip of scooter deck tape. I'll have enough left over to re-cover both pedals 5 times over. He is also happy with coilovers as long as they are a quality brand (mine are Teins) and not a backyard job. Car is booked in for Monday, happy days!
