Can i ask why your fitting such big discs to what looks like a standard hub? are you fitting a jet engine to it? your gunna need some big rims to clear them. :D

The Renault 21 Savanna disc conversion seemed ideal. What's better about these ones?

After looking at buying big brake conversion of verious
companies decided against paying big prices. .
Had looked at Renault conversation which is probably more than enough..
but thinking of doing track days and in my mind at least
bigger is better? ..
have 18" wheels fitted to the viva so shouldn't be clearance issue's ..
The engine running 6psi boost and I know it's good for at least 16 psi which will be around 450 bhp ish
at the flywheel (after saving some more money for bigger injectors and mapping session ) :)

I think you should scrap the idea, the back of the hubs have barely enough area for standard disc fitment, unless of course you intend to add additional support which might help but ultimately its not good enginneering, the renault 21 discs are more than enough for these hubs.

Why not mount the disk to the front of the hub you will have to redrill the stud holes and maybe the centre bore or fit a spigot type ring ,longer wheel studs if your making brackets to fit the calipers then they just have to be abit thicker. you will have all the strength you need where the wheel bolts on, i have 300mm discs and brembo 4pots on my viva
