hi fella is the car lowered if so you will knacker the new ones in a short time as i have found
as when you lower the car buy say 40mm the angle at which the car sits puts stress to the bush in a direction they are not suited to work at properly so they wear quicker
and i know through the problems i had on mine so i got a new set of new wishbones and fitted spherical bushes and uprated ones where needed the company i got mine from was deflex and at the time they had just only finished testing them so i bought a set and fitted them, can be difficult to remove the old ones speacialy the inner one but outter one i used a socket and a vise for inner one i used a knife heated up red hot and cut around the hole and cleaned them up with a dremmel or if you want use a blow torch to burn the rubber away but i dont advise it unless you know what you are doing
i had gone through 3 pairs of wishbone in a year before fitted the deflex ones and never ever replaced them again
and the car was tight at the front with none of that swaying as the old wishbones start to wear
you dont need to buy new wishbones to do this you can if you want i only did as i needed the car on the road at all times so done the bushes in my spare time and once done an hour to fit both sides then off for the tracking tobe done which you will have to have done after fitting new wishbones
if i remeber rightly the new spherical ones work out cheaper than new wishbones so if the car is lowered i would go this route as its cheaper in the long run
