Here next time u get tires look at this it will give u A better look instead of ur car sitting nose high lol
It won't hurt ur speed is in the read tires, I know this because I have done a 60mph burnout without moving lmao
Btw look at the psi max on your tires before u add more air if they max at 44 I would not do more than 38-40 if they max at 51 like mine u can put 44 in them safely, I've gotten use to rougher ride since I hardly have passengers lol
It should help at 40 not a lot or anything but it will help
