I put some 7k in the front and center today and tried it on dusty tarmac with some old tyres, before on this surface with these tires I could not get the back end to break free at all cos it would just understeer like a bitch! Now, if im not careful with the throttle it will do a 180 on the spot!

What a difference! Should be good on high grip tracks with some new tyres. What tyres do you recommend for astroturf?
