Can anyone tell me what these TSW alloys are called?

[VeeDubGTI16v]

yeah but they will be made so they can EITHER be 4 or 5 stud, anymore holes and its not tsw's problem

and if the customer wants to put more holes in as long as its clamped up nicely on a pillar drill it wont be a problem

anyway cast holes are stronger than drilled holes, just look at drilled brake discs, if you do it yourself at home, they are gonna crack at the drilled holes, whereas the factory cross drilled brakes will be cast

the old brembo website had an faq that was quite clear. it makes no difference whether holes are cast or drilled. they had researched it and decided there was no difference. its another boyracer myth. sry.

found a site who lifted the brembo faq:

yeah nice one

im saying it because i understand what happens to metal in processes such as drilling and casting, not because some boy racer told me, im just using that as an example cos its a car forum.

stop arguing with me tinman its annoying

i'm just using a company like brembo who have done research into it. but hey, what do they know. not like they employ teams of engineers or anything like that. probably a couple of guys in a shed.

[VeeDubGTI16v]

dont you think they are trying to justify why they drill the holes in their discs? which is a cheaper process than casting the discs with holes and why are porsche and ferrari etc discs cast with holes? give me a sarcastic answer for all those questions then

[tinman]

you are right of course.

its not like anyone important uses brembo. i mean, they are a couple of village idiots in a shed just making any old crap up to sell.

[VeeDubGTI16v]

you are right of course.

cmon ladies, settle this in the only fair way.. a duel

at a guess i would assume if you drilled your brakes at home then the reason they would crack is due to them being hardened steel. the excess heat generated in a localised area by trying to drill hardened steel which would be harder to drill would cause a stress fracture due to uneaven expansion of of the less flexable hardened steel.
it would be easy to drill the steel before hardening and/or increasing the carbon %age (ie by case hardening) in the steel.

Now here!! on ebay, Just in case anyone's interested
