how much would i be looking at for a set of the QFMs? What stores would stock them? Ta http://www.qfmperformance.com Quick run down on the pads: - The HPX is a Bendix Ultimate type performance pad, good for about 550 degrees, whilst being virtually dust free, and low rotor wear. - The A1RM is a Ferodo DS2500 type performance pad, good for about 780 degrees, but will still work from dead cold (A1RM and HPX have the same cold friction), and relatively low dust and rotor wear. I run the A1RM in both my daily road car and rally car and it isn't a compromise in either. Depends on what pads you've got in your Corolla. Most of the pads (except for DB1431 and some of the SA ones) are available at standard QFM prices, $79 per axle set in HPX, and $119 per axle set in A1RM. Where pads are covered by QFM's normal range need to be custom made, the pricing is $110 per axle set in HPX, and $149 per axle set in A1RM. Regards, Greg
