Wilwood say that the precision fit does not require dust boots. My experience is four years with this set up and no rebuild required. I track my car 27 days a year. I have gone through rotors and numerous J level pads with not stoppong issues. In fact htis set up with brake duct cooling allowed me to delay braking another 75 feet. Daytime temperatures 55 to 105 degrees in California. I am a very satisfied customer and still get my replacement parts through Russell at 350zbrakes or G35brakes.com

 

Oh noes! he does not have enough PISTONS!

 

well thats great news,cause on most all standard street cars a caliper piston without a dust boot dosent stand a chance.but it seems that the aftermarket high performance bbk manufactures must have much tighter tolerences.i like more informative info then we get most of the time on the forums....thank you.

 

From one who sells hundreds of Wilwood calipers a year and many dozens of brake kits...I can tell you that this arguement is a moot point.

I run my own Wilwood calipers in some of the most dusty conditions (Pikes Peak and other mtn roads) that far exceed that of most any street car. And I do little to "rebuild twice a year" my calipers. In fact in selling BBKs for over 14yrs I've seldom sold seal kits to customers with kits younger than perhaps 5-7yrs.

I'll grant you, if you live in the salt belt of the USA and you do little or no maintenance on your car and in short run it into the ground...you may find that running without boots and the pads to the backing plates then ramming the contaminated pistons back into the aluminum body that you may find your abusing the system.

Other than that foolishness booted or non booted is of little or no concern to the average user.

 

..."Racing Brake"...? lol.........
