As luck would have it, we learned a lot and had much more confidence in the car when we got on the track. It is a great feeling when you win and have built or modified the vehicle you are driving.

Since you showed the Rear End.... here's some photo's of what you may want to consider ....










One of the problems we encountered was filling up our catch can on the rear end .... and we found out that the oil was going out the breather or vent hose into the catch can .... and then would not return to the diff.... then we would damage the differential.....

These are the mods we did to fix that issue...

These are the things we did to KMP259 as well and it has proven very successful.

I just had this same exact issue happen to a CSX6000 Series Continuation Cobra that I completed for a client. The oil pumped out of the differential and out of the catch can and now the the differential has a noise. The car has less than 1500 miles on it and the manufacturer refuses to stand behind their product even though the manufacturer of the differential they installed has told them repeatedly they need to vent the differential differently. Needless to say that my client is not to happy with the way the manufacturer has dropped this problem into his lap on a very expensive purchase.
