I didn't replace mine and they have been fine.
as far as i know they are a reuseable bolt.

Good practice of course.
Worth upgrading to ARP jobbies while its off IMO.

I was told by Burtons that the ARP ones are reusable (though at £60 ish a set they ought to be!), and that standard ones aren't.

depends on the engine and its usage.

any high rpm competition engine - replace with new.

if you can get arp or other uprated bolts, do so.

arp bolts can be re-used.

if its a relatively stock engine - follow manufacturers guidelines.

and always do the bolts up to the correct torque setting.

If they're OEM they may be stretch bolts so no you shouldn't re-use them (even if some people say you can).

Flywheel and clutch in your lap is not a good site. Years ago a clutch blew in a race Ginetta, the pressure plate lodged in the door, luckily missed the drivers feet and legs, scared the u no what out of him.

Fly bolts on the ze are not stetch to yeild. New ones do come with a thread lock compound on them. I re-use them with some fresh thread lock on them.

as above, use thread lock on them if reusing
