is it possible to increase the tyre grip against the ground on a csm mod?

i've been playing gp4 2018 mod and yeah it's pretty cool and stuff but i'm more used to playing the vanilla gp4 but with the tyre grip against the ground at ~150% with gp4 tweaker which we all know that we can't use when playing csm mods. i just wanna increase that tyre grip against the ground.

is it possible? what do i have to do?

thank you.
