bells and rotors, 310mm x 28 mm, when hot ie doing a track day how much would the rotors expect to expand by size wise ??

cheers.................matt

 

anyone at all ?????????????????

only 4 people even bothered to have a proper look

good old passionford eh

 

why get shitty about not getting a reply when not everyone has the technical data, the information about the material used, the LLoyds specification for the materials, and the heat range in which you are expecting expansion?

 

forgot to add

 

and in which direction? thickness, or diameter?

negligible amounts i would think. why do you need to know? clearance issues?

 

not gettin shitty about it paul just you ask a genuine question and only 4 people look at it !

whereas if i said top gear is on at 8 then i would of got 20 odd replys

not having a dig at anyone here by the way either

 

nick thanks for the reply

yes clearance issues with the ford calliper carrier that we had to modify, dont want to be goin round croft for the rotors to expand that much they fook the brakes up !

cheers.................matt

 

well, as i recall, all materials used have to be at a certain Lloyds specification and the heat buildup from braking should not have an affect if they are made properly using pukka materials - i'd say 0.1mm tops width and a negliable amount for diameter

 

what size rotors have you got on there? the expansion will obviously be a percentage of the starting size, but i can't imagine it being more than Graceland suggests. being in the rail industry, he probably knows a lot more about it than me.

 

they are made by hi spec tho pmsl god know what will happen lol

they are 310 mm x 28 mm rotors

i didnt expect it to be too much expansion but when i hareing round the track i want to know my brakes are going to work properly lol

cheers........matt

 

mate of mine, Dave, he has hispec 310mm roters and ally bells on his astra - not bad stoppers using the standard caliper, no problems as yet
