i have powerflex and can not complain, car felt 100 times better than standard
didnt want to go for more hardcore ones, think these are good value for money and transform the car
never tried the others, is it polyrace do some? im guessin you could get group n or a ones as well? wouldnt really know
EDIT - how much are they? as i got full bush set, engine mount, arb mount as well for 90 quid delivered on ebay, cant say thats bad value at all
