Ive hopped this car up with blue shock springs at front, purple at the rear, purple alloy locking wheel hubs (cant be seen), racing fuel tank, fuel filter, purple alloy rear engine brace, fiberglass brake disc, allumininum brake disc hub, 1200 mAh hump battery pack. I dont plan to do any more to this car since it is no longer made, but i have spare parts to keep it going for ages.
