These things tend to rely on
A) how well you know the garage that is likely to do any warranty work, and
B) whether any claim is worth the warranty company sending out an assessor before they agree to anything.
If A) is pretty well, they are more likely to try and help you out when the warranty co. ask all their qualifying questions.
If B) is a yes then they are very likely to try and get out of a claim stating that the car is modified.
I would say check through the terms and conditions of the warranty very carefully before fitting anything that cannot be reversed quickly before trying to make a claim, anything that improves performance (even by the smallest of margins) will be seen as putting "extra strain on the manufacturer tollerances" and could therefore be the "cause" of all sorts of, in reality, completely unrelated failures.
'06 GT JTDm - Gone but not forgotten!
'54 SEAT Altea - Family bus, pleasingly quick too.
