I've been given a set of uprated ARBs from a Seat Leon and the part numbers seem to match for a my Octavia. Would there be a noticeable difference using these with standard suspension or should they be installed as part of a full kit?

 

Thanks.

If you suffer from oversteer then install uprated front ARB

If you have problems with understeer install rear ARB.

Want to make more stiff all around where balance is already OK install both

Putting on standard suspension is fine, that way you get better cornering, less body roll, better balance without sacrificing comfort. In fact you weirdly get more comfort because the car isn't lolling around.
