Thanks for the replies!

Many people uses the jaguar rear. It will handle power but will also be to heavy. As the car is pretty light it will only be mild power tuning. Thats why i thought of using the light alloy subframe and maybe a 7,5" uprated diff. If the mk6 frame not would be to wide to fit (shorten would reduce the power handling worse i think) i then will make my own adjustable control arms as the width is not the same of capri/escort. But people uses sierras rear susp. wich seem to fit and sierra should be wider than escort.

The car will have cologne not and it approx 69" wide the info I have found. I will check out the mustang parts as newer cars should have some alloy stuff also.

Thanks in advance!
