The short answer is, "Yes. These StopTech brakes I designed are better than the Wilwood Aerolites. I still like, recommend & sell Wilwood Aerolite 6 brake packages. They are a quality product & the most rigid caliper Wilwood makes. Caliper rigidity is a big deal that the average car guy doesn't understand to look at.

The brake packages I designed utilizing StopTech ST60 calipers front, ST40 calipers rear & Stoptech's lighter, cooler running 14" AeroRotors ... are a higher performing product, with many more benefits & features ... as well as a significantly higher price tag. I didn't design these new brakes to be price competitive. I designed them to be the best possible brakes you can buy for a Pro-Touring car ... especially if the car is also used for autocross & track days.

I feel these two brands of brake products appeal to different customers. The Wilwood Aerolite 6 packages are the "best bang for the buck" and the Stoptech packages I've created are the very highest level of performance braking for Pro-Touring cars.

The long list of Features & Benefits my StopTech systems have over other brake systems are:

• Calipers with more rigidity & less flex than any other caliper available to our market*
• The bridge of the ST60 caliper is so strong & unique it is patented
• The caliper bridge is removable on both ST60 & ST40 calipers for easier brake pad changes
• Firmer pedal feel from the high rigidity calipers = Gives driver better sense of braking degree
• More net braking force per piston area due to less caliper flex
• Much larger piston area / Critical for manual brakes
• Cleaner release of brake pad during hard stopping = Easier to modulate braking force
• Piston dust seals for longer piston life
• Anti-knockback springs behind the pistons = reduces or eliminates knockback
• Floating rotors = reduces or eliminates pad knockback
• Patented Aerovanes built into AeroHats® = pull cool air across the rotor surface
• Patented Aerovanes built into AeroRotors® = pull more cool air through the rotor than any other rotor
• AeroRotors® run 11% cooler than other rotors
• These 14" StopTech AeroRotors® only weigh 16.2#
• That's 2# to 5#lighter for less rotating inertia = Quicker acceleration & stopping
• This Brake system was engineered from scratch 100% for manual brake Pro-Touring cars
• Correctly matched front & rear piston area for balanced front & rear braking
• More braking force (3460#) than a ZR1 Corvette
• This is BIG = One pad works well for Street, Autocross & Road Course Track Days
• The StopTech 309 Pad has great cold bite for autocross & street braking
• The StopTech 309 Pad does dust the wheels / Just less than all other Autocross & Race pads
• The StopTech 309 Pad has very little squeal
• The StopTech 309 Pad will handle up to 1200° of temperature with ZERO fade
• The StopTech 309 Pad will handle up to 1400° of temperature with modest fade
• All other street & autocross pads fade & lose braking force in the 700°-800° range
• The StopTech 309 Pad utilizes modern "Adhesive Technology" where is lays a layer of pad material on the rotor surface to rub against.
• A lot of other brake pads out there utilize "Abrasive Technology" & wear against the rotor ... eating it up.
• The StopTech 309 Pads do NOT eat up your rotors
• The StopTech 309 Pads retail for $120 front & $65 rear = Only $185 total
• The StopTech 309 Pads last like street pads, not race pads
• The StopTech 309 Pad is only a part of the magic. The large piston area, allowed by the rigid calipers combine with these pads to create the awesome braking force & characteristics
• When we run these pads in smaller piston area brake systems, we achieve some of the benefits, but not the total braking force.

Depending on application, we sell the Wilwood Aerolite 6 front brake packages for $1819 to 1899. (Same as Jegs & Summit)
My StopTech front packages run $3295 to $3495, depending on whether the application needs hubs or not.

I didn't list the front hub features above, because some brake packages (like the C5/C6, Speedtech ATS, DSE, Roadster Shop, AME & others utilizing the C5/C6 mounting) don't need hubs. I’ll do that in a separate post.
