Which Brake Discs

[Martin]

I am getting some new front discs for my williams and need to decide between these. http://www.bbperformancetuning.co.uk/products/department.asp?deptid=102http://www.bbperformancetuning.co.uk/products/department.asp?deptid=102

Which Tarox ones 40 groove or drilled/grooved?

Alright bud,

Ive heard its best to go for just the groove because in some circumstances on drilled discs they can crack from the hole to the edge of the disc!

But Ive been speakin to BenR and he saids not to bother with them just go for some rally discs only about 35 nicker!!!

Thinks thats what Im gonna go for when I get hold of some valver or willy calipers!!!

Ive got the tarox 40 grooves on my williams and i think theyre wicked. I also got advised against buying cross drilled due to the potential of them cracking.

They wouldnt crack unless theyre cheaply manfactured. They wouldnt generate enough heat to do so.

yeah group n discs from Rally Design are are good.

The reason that they would crack is down to how the holes are formed.

Drilling the discs after casting and machining creates stress concentrations around the hole. The best drilled discs are not drilled at all but have the holes cast into them.

This difference is like the difference in quality between forged and machined bolts, forged being better because of the grain structure flows.

I have used the Rally Design discs for about 2 years now and they are easily the strongest available and amazingly the cheapest . I tried both varities of the Tarox , and both were equally as crap as the other . Neither could last a full day on track .

I also tried just about every make of disc available in the standard size (256mm) and found the Rally Design ones strongest and longest lasting with Renault OE about the same . Everything else was miles behind and a complete waste of money.

Imo of course
