Sorry bro...
There is no adjustment..... and from the time you start to feel serious slipping to the time it is almost completely gone will be very short...... believe me I know...... when you get it replaced... get price comparisons with a few higher end performance clutches..... some of them are even cheaper than a MAzda replacement...... just a thought..... DO NOT go with a no name clutch such as AC delco..... It doesnt fit..... I know this for sure also...... FORD is ok I guess... but if you have the choice go Mazda or performance aftermarket...... and it will be expensive any way you do it... im warning you now.
