personally i would avoid deflex, on a mk5/6 escort they are a complete c*nt to fit, especially if you dont have a 500 tonne press to hand.....
i have fitted one set to my cabby, they are ok at the mo, but the set i fitted to my mates car, he has had no end of trouble, he got through 2 ball joints in 1 month, fukked a suspensoin strut, done the inside edge of his 3 week old tyres, and why??
because the deflex bushes on the passenger side had siezed!
if i were to polybush the lower arms on my mk6, i will get superflex - they are powerflex bushes, but powerflex dont sell them, you have to buy through a distribtor.
for the mk5/6 escort they are £125 incuding VAT compared to deflex £55.
you get what you pay for!
