It is now widely recognised that short big bore shocks are a step forward in electric Touring Cars. However most of them require the use of shorter springs which may not always be ideal. Shorter springs are, by nature, less linear than longer springs giving a more aggressive feel to your car. Some springs in particular have estabilshed themslves as a must have in certain conditions such as the HPI Silver on asphalt and the Yokomo Pink/Blue on carpet.

Here is how you can fit long springs on the True Big Bore shocks fitted on the VBC Racing Wildfire D06. This is not the only way to do it of course, but this is how I did it. Please note that this mod will only allow you to reach decent ride height with small tires only (LRP CPX, Ride Rex34 and Rex30 in particular).

First you need a different shock bottom connector and spring retainer combination. For that matter I used VBC Racing A-03-VBC-0086 Aluminium spring retaner and A-03-VBC-0066 Shock bottom connectors. The Aluminium retainers sit lower than the standard plastic ones, however they do not fit the TBB bottom connectors which are too big in diameter.

In order to lower the retainer to the correct height, you will need to shorten the rear (Rear ONLY) bottom connectors. They come at a 15mm length, you need them at 13.5mm. I cut them using a sharp cutter, no doubt a dremel will do the job as well. Make sure that you cut them both at the exact same length, use sandpaper if needed.

When screwing them back on the shock shafts, make sure your shocks are 59.00mm long from top to bottom. This mod may alter rebound settings a little bit since more shock shaft is exposed, I didn't find that being an issue at all however.

When fitting the shocks back on the car, you will need to space them by 2mm from the arms and the shock tower in order to ensure enough clearance between the retainers and the lower arms.

Set your ride height and thats it, job done !
