Giz-on your xray. Are you running it bone stock? I was thinking of blue gray springs,those shock pistons you posted and a king headz motor mount with the extended arm to help with the flex. I've just been running mine around the back yard. No big jumps,bumpy tho. The car is a lot different then my jammin x-2! I also noticed that with the smaller air filters,running richer. I have a bigger body on order to run the big filters. To me these little air filters are like trying to suck a milk shake through a coffee stir straw as opposed to a regular straw!
