Uptravel
A great feature added by Robert Pietsch in the MTC3 is to limit the uptravel on the front and the rear of the car.
By setting the height of the grub screw in each corner (the grub screw mounted in the front bumper A2440/rear body posts A2439), the lower suspension arm may have a limit before the shock is fully compressed.
There are multiple ways to measure properly.
The uptravel value (in this example of the front left = 14.6mm) is located in the setup sheets and can be checked in the following way:
- 1.Remove the shock.
-
2.Put your car down onto a flat setup board.
-
3.Lift and keep the suspension up.
-
4.Slide your droop gauge underneath the steel ball (A2819) and check the height in mm.
Alternativly, Ive added two other methods.
First, with the car flat on the setup board using a 10mm droop block underneath a ride height gauge, then measure in the same way as I described using the droop block above.
Or, in case the car isn't flat on the board or your board is not flat, put the car on your 10mm droop blocks, then use a 20mm droop block (yes, a bit random) under the ride height gauge.
Practically in my opinion, limiting the front further (so the arm can move up even less) may give some more cornerspeed but sacrifizing a bit of overall steering - worth to test especially on carpet or higher grip conditions.
Limiting the rear can be helpful on bumpy tracks and therefore also high speed to have less bottoming out.
In general, useful for bumpy tracks as well as you preferably want to use the car as low as possible to gain performance but would like to limit the amount of chassis touching the surface at the same time.
