All cars will have some "slop". Trying to get rid of all of it is the wrong thing to do. If your car runs well, then why worry about it. If you feel something is wrong then replace a few parts if needed, but don't think that having some slop is horrible. I have had many, many cars in my 27+ years of R/Cing. The slop allows the car to center up when a force is aplied to it. It won't just wobble down the track. One of the best things in my opinion about the TC5 is how fair the pricing is on spare parts, when things get out of shape or worn after many runs then just replace some parts and it will be good again.
