I've no idea what you know about cars and driving so bear that in mind, but a flip side to what you'll get in Fabia Projects, if you want some (opposite) tips and info on considering car tuning. I'm sure you would agree that the first part of tuning is full and regular timely servicing, maintenance and repairs for the whole car - fiddling with things comes after. Once that is fully sorted you might move on to better lubricants for additional protection margins for the extra push at and/or passed the usual car's parameters. You always sort your brakes first along with the suspension (tyres come into both of those for safety as well as performance), get the geometry checked and sorted and adjusted with any changes you make each time to suspension, wheels/tyres. Always last is anything to do with the engine, check that no changes are required to clutch and transmission from engine changes if you're going far with the engine. The engine should never be beyond anything else on the car, you want all in balance. Many "improvements" can turn out to be not necessarily so in real world of (legal) driving on public roads particularly if they take the overall balance out of the car. Modern cars are already generally oversized with wheels and tyres and over lowed and over-stiff suspension can often on some roads make things worse rather than better. Here's the bit you would won't like, the best tuning you can do is driver training, the benefits can also transferred at no extra cost to future cars and sometimes negate the need for more extreme tuning on the car.
