Good tools are very important!
Integy also makes their hex drivers in metric.... I wouldn't buy a SAE set if you have a metric car. The only size that is nearly identical in SAE and Metric is the 5/64" is the same as 2mm. This is the main hex screw on a Kyosho 1/10th scale. The other size you will need is a 2.5mm. The main cap screw size and motor screw.
SAE cars like Losi and Associated use more screw sizes...
Bottom line is get what you need!
