Touring Car tweak help (Tamiya 417v5)

[cs8sz]

Hi,

Please help!

I have a tamiya 417v5 which for some reason is massively tweaked. If I take all the wheels off and put the chassis on a board it is flat as a pancake. If I then setup the ride height to be 5.5mm on the rear and 5 on the front making sure all the spring collars are identical left to right, and then put it on a tweak station the car is miles off, and requires loads of extra pre load on some of the shocks.

If I don't use the tweak station the car is awful, is there any other way around this does anyone else have this?

I have made sure all the shocks are identical lengths.

Also it really messes up trying to get the correct droop due to the chassis being at different heights.

Thanks in advance

Chris
