ok, here is how d/line works as regards mods. u declars your mod when getting a quote, if it is in a list on puter, then they add it, up 2 max of 6 if i remember correctly. if it is say a strut brace/quickshift u usually refer to underwriters, and they have the final decision. all this depends on the car,age,driving exp,points/convictions and/or claims. in all honesty phil u would b better off with a/flux or someone like cia. these guys r used 2 dealing with mods and know there stuff!! hope this is of some assistance.
