Not had a claim with admiral but do currently have a few modifications on the car (mostly exterior, no engine work yet) and it barely touched the annual cost. Unfortunately ive also asked about engine modifications and its definitely not their area of expertise but once you start playing in there you have to expect to go to a specialist insurer really.
As with all but one comments so far, their customer services cant be faulted in my experience and the general price of insurance is pretty good for me.

. Would happily recommend both. Currently with Admiral.
