The Zeta-R incorporate the Straight Steering Arms that eliminate the need to use a inverted track rod end kit.
This design reduce bump steer, and also prevent damage to the track rod end from stress of lowering the ride height of an EP3.
This will also work wonders for you if you want to go low because the track rod end will be place under massive amount of stress if they were use with the standard V-shape steering arm.
This can cause the track rod end to fail needing replacement that cost £££.
And is just not good to have parts fail on you in general.
The Zeta-R coilovers also gives you front camber adjustments via the pillowball bearing top mount, and 32 stage damping adjustment.
The only downside is that I am not 100% sure if the rear will go low enough for what you are looking for.
That is because the design of the EP3 rear suspension is very short to begin with.
I redesign the specification in the rear to allow the rear to go as low as possible while retaining an acceptable amount of damper travel.
To make the rear go any lower will mean reducing damping travel, therefore reducing compliant ride over fast roads and damping performance in general.
