Because I know TW1T has a speedway, car different/longer control arms and bending the struts (some speedway guys have been doing this to also 'bend' the rules) are not permitted.
I'm not 100% on this but I reckon coilovers wouldn't be either.
So considering what Evan has said about the camber tops not working to there designed effectiveness without coilover, you might as well just file the strut tops holes a MM. Woohoo!
You guys (junior speedway in general, not specifically just TWF#14) are honestly getting a bit too serious with your junior cars and trying to be at the top. Let the kids learn how to drive and enjoy themselves, then step of the competiveness when you step up to another class of speedway car.
