With a 9 second car even if you do drive it on the street I bet its not enough to warrant the locker. I would go with the spool as its the most simple and less likely to fail.

I will be running a normal Detroit locker in my 60. I have never broke on yet, little noisey on corners but I do not autocross my car.

In case there is any confusion, the E-Locker RSNAKE ia reffering to is an electric locking system which can be locked solid as a spool or unlocked to operate as a posi unit with the flip of a switch on the dash. Weight wise, it was MUCH heavier than a spool, but I did not notice any power loss from the rotating assembly. I installed it after having the ladder bars fatigue and break from driving 18.5 tires with a spool on the street. The ARB Locker I was refering to is a similar unit, only it requires an air supply to lock the unit, and is "open" when unlocked. They are more commonly used in 4x4 trucks for rock crawling. The Detriot locker is a mechanical posi type unit and does not fully lock a rear end. There have been instances, particuarly in 4-speed cars, where the Detroit unit can create an unequal power distribution when power is first applied or between shifts. I ran one in a 383 4-speed car and every shift the car moved a few inches right before it locked again. Had an Automatic car with the same gears set (8-3/4) and it ran straight. And if anyone can make a Detroit locker work, it would be Dr.Diff

Scott - Am I understanding you right in saying you switched from a spool to an E-locker and now to an ARB locker? You have not noticed any change in ET due to any of these changes (before the E-locker broke)?
I believe the Eaton E-locker is an open diff when not engaged. The Auburn ECTED has an electric lock function and is a posi when not engaged.
I did not notice an ET difference switching from the spool to the E-locker, and it was definitely a posi when unlocked. The car was running consistant 11.0's on motor, and 10.10 with a hit of NOS.
The ARB unit is going in a new project.

ARB has a great reputation in the four wheel drive world. Most any problems people have with them involves the air lines and not the unit itself. Since a race car doesn't have alot of suspension travel and ideally stays out of the mud the air lines should be cake.
My understanding of the auburn echted is its a limited slip all the time, it never fully locks it just becomes a "really stiff" limited slip unit. It gets alot of mixed reviews from the jeep forums I am on.
