yeh m8 i have asked that the JC kits as well, i have been told that it is allowed at the end of the day however if anything goes wrong that is related to the kit- they will not fix it... so for example if the gearbox failed because of the extra power you'll have to pay for it... thats what i've been told- hope that helps i'm in deep thoughts about whether or not i should get it at the moment- the power upgrade is a bit hefty for me (£2500) but might go ahead with that body kit
