First a little background info. Although my Viper Project car has been evolving pretty well, a problem it has always had which seemed unsolvable is that it would sometimes enter FRC's hairpin corner (around Caiman Pond), start to go round, then suddenly understeer straight into the outer barrier. The only option was to be extra cautious at that point of the track, something that either slows the lap time or, if I go too fast, results in a de-slot. Nothing I tried to stop this ever worked. Nothing until this latest modification.
What I realised might solve the problem is adding some up and down play on the front axle, but the Scalextric chassis does not allow this because the front axle bearings are moulded onto the chassis and are not designed with up and down play. Enter Slot Car Corner's adjustable front axle mounts:
I purchased a pair of these cool front axle mount upgrades and spent time installing them in the Viper last Tuesday night. When I tested the car on Thursday night, try as I might, it refused to repeat the understeer problem. Whenever it de-slotted in that corner if I went over the limit, it would be an oversteer de-slot on the very exit of the corner. Problem solved. Here are some pics:

If you have a car with fixed front axle mounts and want to make them adjustable and/or add up and down movement, I highly recommend this upgrade.
