Did mine anyway). Gotta remember on a fwd the engine, tranny, a-arm bushings are all part of the suspension and they preload. Its a totally different geometry to a rwd. altho both do the same weight transfer to the rear, which in a fwd if its not controlled will cause traction loss.
In a FWD Escort or Focus chassis you would swap in Wagon rear coil springs, and install 90/10 shocks if you can get them to keep the rear end up. If these shocks are not available you can use air bags in the rear springs. You would also swap over to some skinny tall rear runner tires 1-2" taller in diameter then your fronts to get that rack going forward.
As stated above i havn't done the A-arm urathene mod yet, but I have ES Inserts in rear and a Wagon front motor mount.
