S4 chassis

[rcracer]

The back end of my chassis seem to be wearing down i believe its a older version and by the looks of it when it gets a bit more hammer on a outdoor track i could be having problems with the two screws right at the rear, is there any way i could repair it with resin for instance bring the thickness back up again then file and redrill for the srews as i imagine a new chassis will sting me a fair bit....will post some pics of the problem later..

You can drill some extra holes, you will notice on the rear suspension mount there are two inner holes as well as the current two outer holes used to hold the mount

If you use these as well, it will a lot of life to the chassis

Maybe make a thin sacrifical skid plate too out of thin CF or ali?

Those protective chassis sheets might be an idea.

Dude.. that plate is seriously messing with your anti squat. Or maybe its the angle of the photo, but, It actually looks like you have pro squat... NASTY!!!

I'd strongly advise you replace the chassis and get shot of that plate. Either that or as a desperate measure put a similar thickness plate under the front bar, whilst not ideal, as you will raise the roll centre considerably. This option is far more preferable than pro squat though.

Another little tip, I used titanium screws in the back of my S4, they seem to wear less than steel ones and so protect that rear lip better.

The rear of the chassis was changed on later cars, looks like that was one of the very early chassis you have there.
