No, rear beam needs solid mounts on the main bolts, stops the car wandering around the rear beam. Rear arms are rose jointed anyway if you have a six degree beam. Front TCA's are rose jointed, and compression struts take the place of the front ARB for a huge improvement in turn in & braking stability.

Engine mounts need to be rubberised items, Collins ones are very good, made by Lord who make aerospace spec stuff as used on the aircraft I work on. Rear diff hanger needs to be poly, from MSD/Rainbird/GGR- great improvemnt.

Coilovers will mount direct to the turrets, so removes the top mount bush as well...

This is how my Escort is set up, it is on stiff gravel 909 Billies, and is like a go-kart, no slack in the car anywhere at all, yet is compliant and not buzzy/harsh... Well worth the small increase in road noise, which is minimal compared to the straight cut box anyway!

But the rear beam & solid mounts transform any tired old cossie.
