If you're 100mm off the ground Northy then your insurance is voided with them. 30mm drop from standard height is all they allow. Not trying to scare you, just letting you know. I even tried to get that underwritten on my car but it's cemented in their Policy guidelines. I told them that some people (within the club) are with the NRMA and that they are riding lower than that and they simply said to me, 'If they think that they're ok, well they're not. 30mm from factory height no more. So you'd better let them know that if they have an accident they are voided.' Sorry mate, I'm just trying to be of help. I don't want them to screw you over :( mate thats why i have coilover and the spanners :P My initial concern though was what if you had a huge ding, and you couldn't get to the coilovers. I'm just paranoid...and too honest sometimes I guess. Bah, you know what you're doing man lol.
