The most difficult part of the modification is the modification of the power system. Actually, the modification is divided into many parts.
There are exterior modification, chassis modification, power system modification, interior modification and so on.
The modification of chassis is the most common way to replace shock absorber, balance bar, lower arm and rim tire.
The modification of the power system is to brush the program, modify the intake and exhaust, change the turbine, forge in the cylinder and so on.
The modification of appearance is to modify the front and rear bars, modify the wide body and install some tails.
The modification of the interior is to modify the steering wheel, modify the seat, modify the dashboard and so on.
Automobile modification depends on practice and a large number of data, and it is necessary to constantly study it by yourself.
The modification of power needs a lot of tests, and also depends on many professional instruments and equipment and a lot of data.
The modification of the car can't be changed at all, and the safety and driving stability of the car will not be affected after modification.
If you want to learn modification technology, you can go to some big professional modification shops in big cities to learn. When studying, we should first master theoretical knowledge skillfully, and then combine it with practice.
In the process of learning, we should cultivate the spirit of being meticulous, because many screws need to be tightened according to the specified torque and sequence when refitting, so we must pay attention to these details.
If it helps, I hope to adopt it, thank you!
