I don't know if it's the best thing to prepare with a car and race with an other, especially with the x6 and x7 eco that are so different handling wise..
the MP9E is supposed to provide confidence in the rough and loose tracks considering it's so easy to drive and suspensions are excellent.. on high grip tracks the shocks wouldn't make such a difference with the XB9E which is the reason why I thought I could reserve the Xray for high grip
I mostly practice on a local astro track so the XB9E would be used more.. but it shouldn't be a problem as the Xray is supposed to wear better
is there anyone that tried both cars and would recommend one more than another for loose or high grip conditions?
