Yah, Strap Drive is an AP Racing innovation... Supposedly cheaper than the traditional Bobbin Head fixtures, but as I mentioned, more suited to road applications than high temperature track/race applications.
I'm no race engineer, and I can only really go by what I'm told... Which is why I seek out multiple opinions and reconcile data to make sure people aren't feeding me bullsh1t But it isn't a foolproof method, so I'm more than open to what people on SAU think!
Using Ferrodo DS3000 front and rear at the moment... I'm sure that I'll be massively rear biased at it stands, so will play with pad setup and brake bias to fix it.
