The Contour does not lend itself to a high rpm start. It is easy to induce wheel hop and then have the final drive in the trans break.
If you add the inserts to the motor mounts to stiffen up the mounts, you will diminish this effect, but it will still be there.
The final drive in the trans is the weak point. It is the main reason that people add either a Quaife (sp) or a Torson LSD unit. It is also nice to have the LSD, especially in snow. It also provides more control carving your way through a fun canyon.
Even with those modifications, the Contour really isn't a drag race car due to the front wheel drive and poor weight transfer on acceleration.
So in stock form you don't want to have the engine reved much if any when releasing the clutch.
