I don't think that there's a minimum or maximum.
Conditions for a race typically set weights that are required for each horse to carry. These may be different for different horse based on their previous performances. When the weight (jockey plus equipment) weigh more than that assigned they are listed as "over weights" of "high weights".
There is no minimum weight for a horse to be allowed to race in the Kentucky Derby. The weight of a Thoroughbred racehorse is typically in proportion to the horses overall build and fitness level.
During some horse races, officials will insist on handicapping the horses. This process is done by placing weights in the saddles of the horses, and usually compensates for the differing weights of the jockeys.
The amount of weight carried by colts in the Kentucky Derby is 126 pounds. Fillies carry 121 pounds. If a jockey weighs less than either of those weights, then additional weight is added to the saddle of the horse to achieve the assigned weight.
If your horse is not in an equestrian center, when you go to his page there should be links that say "your horse is not yet boarding in a center ...click here..." etc. Click on that, and it will take you to a page where you can select the maximum price and minimum prestige.
There can be 8 nails in one horse shoes. Only if the horse requires 8 nails (maximum). Edit: *** The minimum nails is 5 nails I never heard of such thing of maximum nails on a horseshoe.***
as a horse improves and wins more races, they add weights to 'handicap' the horse. so there is not one particular horse, it's just a racing method for any successful thoroughbrd.

horse can never carry the car. because car is bigger
The maximum weight for a pony is calculated using the same formula as for a horse. A horse or pony should never carry more than 20% of it's own body weight, this includes the rider and equipment. Remember that 20% is the upper limit, anything below that is better for the pony. As an example a 800 lb (362.8kg) pony can carry a maximum of 160 lbs (72.5 kg) in combined rider and equipment weight.
