AP strap drive

[Alistair C]

Saw these featured in banzai magazine - looks like a pretty neat solution to the 'problems' associated with both rigid and floating discs.

So who's tempted to give them a go on their S2 (custom bells needed obviously!)

• Compared with single piece discs the disc is de-coupled from hub, this allows disc to align itself perfectly within the caliper.
• Improved pedal feel and brake response as a result of improved disc alignment within caliper.
• Improved pedal feel at elevated temperatures as disc rotor is able to expand in a controlled manner with little influence from the disc mounting. This greatly reduces disc coning.
• Controlled axial float of disc rotor reduces brake 'knock-off' which can result in an inconsistent pedal feel.
• No free moving parts means that the wear problems normally associated with floating disc designs is not present.
• No free moving parts means that there are no clearances to become clogged with debris and corrosion which would prevent a conventional floating disc from operating correctly.
• No free moving parts means no unwanted mechanical noise from discs.
• Disc rotor and strap sub assembly available as service item for cost effective servicing.
• Successfully used in race applications.

Seems like a good idea, what happens to the straps when you brake heavily in reverse though, wouldn't the straps distort?

Used on bikes too.

Yes, problems might arise when going backwards, but then again, race cars seldom do and neither do bikes. I'm guesing that's why steet kits don't have this design...yet..

Nice system.

The solution to the reversing problem is simple - don't drive too fast in reverse!

Isn't it enough of a buzz proving that S2s are quick going forwards, without proving that they can beat things going backwards too?!!!

remeber my mate driving his 200sx flat out backwards to se if his turbo still worked in reverse

Well surely the Turbo would spin backwards and therefore suck the fuel out of the engine and pump it through the air filter
