So who are you with?

For those mods, I would recommend you give Graham Sykes a call.

They specialise in modified cars, and give you a discount for being with 306oc (Probably, when I got mine I said .net).

I pay £500 a year with all mods declared, with 1 NCB.

They prefer mods which don't increase engine HP, so those ones would suit well.
