Hello guys, I just got into karting with a 20 year old kart. So I first got some used tires, the vega xh4. On a track near me i got a lap time of around 48,3s. Then the front tires were worn down (inner side looked funky) and then i bought some used mojo d2. Because the front tires looked so bad, i also tried to adjust the suspension. Now my time is around 1s slower. Im just wondering, is the mojo d2 less grippy than the vega xh4? Or is my adjustment bad and i should look more into that?
