| Dogboxes have been around for quite sometime. Pros:
Clutchless shifting (biggest pro): Just slight release of the throttle to shift. To downshift blimp the clutch. Its pretty much flat foot shifting. If you apply a little bit of pressure on the gearknob towards the next gear, as soon as you release a little bit of throttle which unloads the tranny the gearstick pretty much sucks into the next gear. Its not as rough as most people make it out to be. Less transmission loss: Straight cut gears don't have same thrust load as helical gears. Strength: With no synchro gears can be lathe bigger, so the tranny is a lot stronger. Cons:
Loudness: Straight cut gears are super loud. Imagine your reverse (straight cut) but 10x louder, then square it. This is the distinctive high pitch noise you hear from race cars (kinda like a supercharger). Clunkiness: Very awkward to shift in gear at low speed/low rpm. Shifting into first you normally hear a big thud. Price: Cost more than a new 99spec box. Durability: If you don't know what you're doing you can wear the dogs out really quick. In saying that these will last a long time if you use it properly. My 2c, this is not for a daily driver, but certainly for any weekend warrior. Good for drags/track/drift because of the quicker shifts. Power level wise, although it doesn't really relate to power if you're around 500-600hp+ then yeah why not. Hope this helps! PS: Brett, I've been in a Pulsar rally car with a PAR box, can't say much about it (its ok?). PPG is nicer in my opinion since its race proven, but I have nothing against PAR. They do seem weaker than PPG though since I've never heard of PPG breaking but I have heard of PAR gearsets breaking. If the GB happens I'll be interested in a set :)
