that any upgrade would be of minimal improvement for the cost? Based on my thinking stock wheels would limit that leverage and I thought I read on here the pads/disk contact area is approx the same. No racing, but always 10 mph over the speedlimit(50-60 mph) on very crooked, hilly roads. If so, I will save my money as I was considering upgrading with my next breakjob. Everything is oem now. Thanks for any input. Sincerely, Doug
