Hi Rich,
Unfortunately they are an "old fella's car" in respect of braking, but with several hundred pounds investment they can have the same torque as a Boxster or Mercedes E320.
We experienced very little in the way of theft of these vehicles, but the problem area with the Fabia/Octavia models is primarily due to quite a number of accidents through failure to stop the vehicle (ie. Hit other vehicle in rear).
Sorry we couldnt help Rich....
Kind regards
Tony
