Lippy , I think you misunderstood what I was trying to say . Racing parts on the street have their own set of issues . Makes no difference if they are Wilwood or Sierra , racing parts are designed for a totally different set of conditions . For example , my racing only pads will glaze up pretty quickly on the street and never come up to correct operating temps if they aren`t used hard . They also wear the rotors .... higher friction/ harder pads and street use do not go together . IMO , if you aren`t going to use the brakes that hard , then why spring for parts that aren`t intended for everyday use ? Just like my cam , which is fairly long . Not very well mannered below 2100 rpm , but great for coming out of a turn .
Check with ERA , but I think they require you to have the ERA optional IRS rear if you want the big front brakes . Also , be careful playing around with different pads as you can unbalance the F/R brake ratios .
That`s why I let a brake guy for Roush Racing come up with the track pads I now use ..... like hitting a brick wall when I get on them hard , but I get rotor wear and not streetable at all .
