Looking at getting some STI 5/6 suspension to replace my jap spec coilovers but obviously they will be 2nd hand so just wondering what to look for example leaks etc.

Can suspension be fixed if there are leaks etc?

Cheers.

If they look clean, rust limited and the spring wipe-off to a nice black or pink colour they are prob ok. If they are off the ca then ask why.
''To fit coil-overs'' is a good answer.

Alternativly, buy from someone reputable, ie API Engines who sometime break Jap sourced low mileage cars.

In good condition with good choice of anti rollbars and alignment, the car will ride great.
