PFF5-303 is an eccentric bush for the M Series or where increased caster is required.
Please check front and rear anti-roll bar size before ordering.
PFF5-304 is designed to fit models where the Anti Roll Bar joins the lower arm, not the shock absorber. They will not fit the M' versions as a consequence.
For the rear trailing arms use either PFR5-306 or on-car adjustable bushes PFR5-306G
PFR5-5630-10 fits cars with standard or aftermarket rear shock absorber with a 10mm pin, PFR5-5630-12 fits cars with aftermarket rear shock absorbers with a 12mm pin.
PFF5-470 only fits vehicles with manual transmission.
