I have a Thule roof rack. Includes 4 feet total:
- 2 each of the 300 which is 6" tall for the front and,
- 2 each of the 387 which is 8" tall for the rear.

This makes the rack level on the roof of a 993 which is what you want!

As a package with the 4 feet, front wind deflector and two square cross bars for $225 plus actual shipping or pick up in zip code 07940.

I have some other Thule accessories we can discuss that are priced separately (bike rack, ski attachment, etc).

Please send a PM if you're interested.

Thanks,
Mike
