Guard TBD's work great. Only way to go if your running Autox; you can dial out understeer. Same with Hill Climbs, the TBD will put the power to the wheel with the most traction.
Haven't driven the Wave TBD, but Bill Pickering just put one into his 901 for his new 914-6. It a 3.2 liter, so looking forward to trying that differential in the car. Should be a terror.
Matt Monson of Guard says that the Torsen design of Wavetrac locks under braking which is counter to what would be desireable in AX. He says the Wavetrac design is deliberately intended to prevent trail braking, which means that all your rotation in a turn must be done during the coast phase of the turn. Their locking mechanism doesn't release until you let go of the brakes. With the Guard, you can rotate earlier and therefore get on the throttle for exit in the direction you want to go. Anyway, in theory it sounds like a fast enter/exit in a tight turn.
I wish someone would chime in on that who has one and tell us if this is what he/she experiences.
I've just used the Guard and know it eliminates understeer. YES!
Not a big fan of trailbraking in autoxing, but do see big open courses, like Crows Landing, where it could be used effectively.
Can't wait to drive a big time torque car like Pickering's with the Wave unit. If it locks up under braking, Bill might be happy as that was the one thing that he didn't like about the unit, wanting to use it at the track as well.
BUT wondering how long it takes from brakes off to unlock; whatever that time is will cost you in autox.
