Thank you. You have rated this product.

This upgrade option changes a brake kit you are purchasing from us TODAY to the Dynapro 4 piston caliper versions with dust boot seals. Price covers two calipers or one "kit".

This is an upgrade option available ONLY on the Wilwood Dynapro 4 piston brake calipers. This is available for both the black and red versions of that caliper (price is the same for both). Sorry, this is not available for 6 piston, Dynalite 4 piston, or rear 4 piston calipers. If you buy this option with a kit that is not compatible we will refund this back to you.

This price is an upgrade cost ONLY. If you buy this without purchasing a compatible brake kit from us in the same order we will refund this back to you.

Why dust boots?
Factory brake calipers use dust boot seals to keep dirt, salt and other debris from getting into the gap between the caliper piston and the caliper body which can cause premature wear. We occasionally get a call from someone asking if our brake kits have dust boot seals because the factory calipers have them and so they assume this is a feature they need to be concerned about. To be frank - nearly all Wilwood brake calipers just like all racing brake calipers, do not use dust boots to seal the caliper pistons. This is intentional and done for several reasons, including the point that rubber dust boots can catch fire under extreme brake heat. The pistons fit tightly into the caliper so they seal without the need for rubber seals. In our decades of experience with thousands of Wilwood calipers this design has proven itself completely reliable both road and race track use. HOWEVER, if despite that vote of confidence you are convinced that this is a feature you want to have in your brake caliper AND if you do not have plans for race/track use (remember that bit about the boots not being suitable for high heat) then we have made this option available for you to get the dust boot version of the brake caliper for that added peace of mind.

You guys are great! The new suspension is in and the ride is much improved. Thanks for the great service.

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
