I rang for a quote from Admiral who stated that they wouldn't insure a 350 with mods!
I'm also with Flux now . . . . .
i do think admiral make it up as they go along some time or the telehandlers have very little idea about what there doing
as i insured my is200 with them told them it was lowered with wheels no issue
my friend at the time had a civic fitted coilovers told him he had changed the suspension and they told him unless it was out back to stock they couldn't continue his policy
I think I'd check your policy wording Steve, I was under the impression that Admiral didn't accept modifications, from experience some of their call centre staff wouldn't know the difference between a steering wheel and wide wheels!! My experince was from 2 years ago so it may have changed, just a heads up really.
