If your going to be modding your car it's pretty pointless to get an extended warranty since it will just give them more excuses to not honor the warranty. The gold one seems to cover everything but I would make sure it doesn't specifically exclude items like the clutch or brakes.
IMO Compare the total cost of the warranty and figure is it worth it for you. Also many insurance companies offer mechanical break down coverage for cheap on new cars and you have a few months from purchase to get one of those.
The most costly thing that people need to replace early is the CSC and then you'll still want to pay out of pocket for an aftermarket replacement, so the warranty would only cover labor costs, guessing $600-800.


What is Mechanical Breakdown Insurance (MBI)?
Mechanical Breakdown Insurance covers many mechanical repairs to your car, protecting you from expensive repair bills. This coverage is only available for vehicles with less than 15,000 miles that have been purchased within the last 15 months. A $250 deductible per claim applies. Mechanical Breakdown Insurance is similar to a dealer's extended warranty protection. It's in excess of coverage provided by the manufacturer's warranty.

Mechanical Breakdown Insurance covers repairs to the following systems:

Engine, Steering, Air Conditioning, Transmission, Cooling, Brakes, Drive Axle, Suspension, Electrical

EXCLUSIONS: MBI does not include regular maintenance services such as tune-ups, suspension alignment, wheel balancing, filters, lubrication, coolant and fluids, spark plugs, brake pads and lining, brake shoes and tires (includes tire wear and/or tire damage). Breakdown repairs made necessary by intentional damage, rust and oxidation, misuse, or improper maintenance are not covered. Mechanical Breakdown coverage is in excess of coverage provided by the manufacturer's warranty.
From my policy runs a little bit under 200 a year. I waited a year to get it added because the factory warranty still covers a lot.
