Had so much failure printing the suspension arms because it likes to either get snapped or broken off from the supports since I was using a A1 (bed slinger) printer but had so much fun assembling it. I would recommend to insert the wheel hubs onto the wheels first before you glue them to the suspension especially if you are planning to put bearings. This can prevent from your suspension arms from possibly snapping during assembly if you're not careful enough like I do since slotting the hubs into the bearing are very tight. PS: Please make a Toyota AE86 and Datsun 240Z. I would definitely buy it
