Dave, what are these knuckles (do you have a pic) and can the SRT-8 knuckles be upgraded on the regular models. Thanks.

DZechhousen; Thanks for clearing that up. I admit that I am a bit of a novice about this car, but I'm working on it. I should know something about it by the time mine gets here.

The StopTech brake system was carefully engineered and tested to make sure it worked well with the factory ABS and dynamic stability control. You can check out my "diary" of a test day in California a couple years ago when the 350Z was first coming out: http://www.zeckhausen.com/Testing_Brakes.htm. That will show you some of the test methodology to ensure the brakes work well with the vehicle electronic control systems.

I've had plenty of opportunities to play with the StopTech 300C 4-wheel kit in snow over that last couple weeks. And it works great. Firm pedal, easy modulation, and the ESP works the same as it did with the stock brakes. It makes me wonder how we ever got along before stability control systems.

You mentioned some people say it is "touchy." That's how one would describe an overamplified system with caliper pistons that were too big for the rotor size. That's not at all how one would describe the 300C kit. There's no nose dive and the brakes are easily controlled. Anyone within driving distance of NJ is welcome to stop by and try it out. Who says it is touchy? I haven't heard anyone describe a StopTech kit that way.

The knuckle (or "upright" or "kingpin") is the Grand Central Station of the front suspension. It's the chunk of iron or aluminum that the wheel bearings, sway bar end links, tie rod ends, upper and lower ball joints, and shock absorber all attach to.

At this point, I don't know how many suspension components are unique to the SRT-8. So I can't yet tell you if we can swap out the 300C knuckles for SRT-8 knuckles without also changing a dozen other components. I expect this will all be well understood within the next six months or so.

Brakes

I have to admit I know absolutly nothing about brakes other than hopefully they're supposed to stop you when necessary. I have a few questions however. On the Chrysler SRT site under handling, they state:

SRT6 Crossfire 60-0 mph is 115'
300C SRT8 60-0 mph is 110'

On the Dodge site:

Viper 60-0 mph is 97'
Ram SRT10 60-0 mph is 118'
SRT4 60-0 mph is 118'

I couldn't find anything for the 5.7L 300C stopping distance, but it seems to me that the Crossfire and the SRT4 should have a lower number than the 300C SRT8 given that they are lighter. Either that or the 300C SRT8's brakes are far superior to their braking systems. Are there any 60-0 stopping distances available for the 5.7L 300C?

Your last statement is correct, despite extra weight SRT8 brakes overall superior to SRT6 and SRT4, grippier tires and road surface type & condition play a factor too at the outer limits of braking. Sticky tires can stave off ABS intrusion into the stop, giving max stopping grip, and shorter distances.

60-0 300c
Motor Trend 122' Road & Track 126'

Well, the brakes on the 300C are not quite "world class" as the SRT-8's are, but they're pretty darned good.

Yes, there are stopping distance numbers available for the 300C. As part of the development of their front and 4-wheel brake kits, StopTech conducted extensive testing of this platform. They measured stopping distances on the stock brakes to obtain a baseline, then they measured stopping distances with front and 4-wheel big brake kits installed. These tests were conducted on the same car, same day, same test driver and at the same track. The stock Continental ContiTouring Contact tires were used.

Ten stops each were performed from 60mph, 80mph, and 100mph. Each stop was measured with a stationary radar gun, feeding data into a laptop. Accuracy of the test fixture has been confirmed to less than 2 tenths of an inch.

The average stopping distance for each of the three speeds is:

60-0 mph
  • Stock: 124.50 feet
  • StopTech front brake kit: 121.77 feet
  • StopTech 4-wheel kit: 120.44 feet (4.06 feet better than stock)
80-0 mph
  • Stock: 221.57 feet
  • StopTech front brake kit: 214.22 feet
  • StopTech 4-wheel kit: 211.07 feet (10.5 feet better than stock)
100-0 mph
  • Stock: 343.90 feet
  • StopTech front brake kit: 337.56 feet
  • StopTech 4-wheel kit: 327.16 feet (16.74 feet better than stock)

For more details on the test methodology, you can check out my write-up at: http://www.zeckhausen.com/Testing_Brakes.htm

I doubt that lug pattern has changed. It should be 5x115.
