I recently got three Slot.it cars [two GT40s and an Alfa] and have been going through tuneups and tweaking to get the best out of them. I agree with what nhdungeonracer said about it. The front axle has been interesting and required the most care. When I took the magnets out initially the front end lifted on each of the cars. If you have this same problem, you might want to try what I did.
I worked the braid a bit, and then went to work on the front end. I needed to get the wheels down to meet the track, as they were in the air by about the width of a piece of construction paper.
Not sure whether your front end comes with the axle blocks under the axle or grub screws [mine all came with blocks], and I found those to be a bit limiting as far as allowing for the wheels to travel downward. I don't have the grub screws to add to the bottoms yet, so I just took the blocks out. To tell the truth, they kind of flew out when I was making an adjustment to my front axle and accidentally had a rather violent shakeup trying to get the wheel off. I was thinking "what if" at the time, I just wasn't expecting to have to think "it had better". The blocks were only stopping downward travel of the axle assembly, anyway. And one of them was already causing binding issues [I cut a groove in the top to stop the binding]. Besides, simply due to their construction - sitting freely on top of two posts like that, tells me that they are designed to be removed if desired.
Once they were out, the wheels rested on the track like I wanted them to. Not too heavily...just lightly sitting. I still had control of the upward travel of the axle assembly by way of the top-mounted grub screws, and adjusted those while the chassis was on the track, leaving just enough room for a little flex, but not enough to raise the opposite back wheel off the track if I pressed down on the front.
This is only a temporary fix, mind you. There's probably something wrong with doing it this way that I just don't know yet [and hopefully someone will say something if there is], but so far I've had good results. Mauricio also said that parts of the front assembly were there to help with the realism of the racecar, but that they aren't necessarily the best suggested setups for racing. He suggested what rhdungeonracer said, which was to have skinny tires on the fronts and have them just above the track in a tripod position. For my home track, I think four wheels down is good for me. I can see where the tripod could improve speeds by lessening friction, and that's cool, but I'm not sure if it's for me. If I eventually start competing, I'll consider it.
I would suggest that if you try taking the axle blocks out, do it with the consideration of eventually getting a set of the 6mm grub screws to hold up the axle properly. That's my plan, anyway.
I, like hkrslot, also have a warping issue with one of my chassis, and I'm planning on doing that fix as well. I've talked to Allan [Audi1] about his success with it on the long term, and he said it worked great. I discovered it when I noticed the rather lopsided adjustment I had to make to the front end of one of the cars to get both wheels down.
A little body float, a little pod float, trued backs and fronts and that car should rip.
Not sure what track you run on. Mauricio suggested to me to run P6 on my Carrera track, but that's before he knew I painted it with a latex. The stock C1 tires work great on my track. If it's another brand of track, I'm sorry, but I don't have any tire suggestions.
