In refference to the strength of a Jag rear end:

The XJS is considered stronger than the unit most often seen in replicas which is the XJ6 set up. BUT, even the XJ6 rear end with high horse power seems to hold up really well in a REPLICA COBRA application. I think that is because of the cars relatively light weight combined with the "traction" problem!

DV (Ed Combs) had trouble blowing up 9" Ford third members and THERE about as strong as you can find anywhere! BUT, he was launching HARD with slicks out of the hole. IF the tires bite on a hard launch you CAN destroy a Jag rear end! With street tires or moderate slicks they can take a LOT of punishment.

But your on the right track, if the tires DO hookup, something has to give!
