Outer Limits 4x4 Board

how much for front radius arm bushes for a gq and i heard that the gu ones are slotted, do they fit and are they worth it
all mine are seperated from the center pin and ive developed a wobble from 50 to 80 kph
prices and thoughts welcome

$160 for slotted bushes from Haultech engineering

ive also been told by a bloke in the comp scene that you can also use 80 series radius arm bushes as they are the same phisical size and are also slotted and allow more flex, thou i havnt tried it yet,
