Dear Sir,

Thank you very much for your enquiry, unfortunately there was an error in
this recent advertisement and unfortunately we have not yet developed a
sequential product suitable for the Subaru Impreza.

We are currently developing Quaife dog engagement & synchromesh gearkits -
internal gears to fit within the standard gearbox casing.

We hope to have these products available early in the new year, dont
hesitate to let us know if you would like to be amde aware when they become
available.

Kind Regards

Rachael Hurd
