The safety devices cage i have seen for the Saff was awful, poor fitting and not the best quality.

If you want one that is designed properly that fits with the whole interior in place then you want what i have in mine.
The cage was fitted before any interior was removed, is excellent quality finish, superb fit to the car (nice and tight to the body). It has removable door bars, properly fitted and bolted in place on mounts fabricated in the car.
Fitted and made by PROTECTION AND PERFORMANCE in Skipton.
