Default XRAY T4 anti dive



Im tryng to set up the front anti dive on my T4 and I think the X-ray Manual and the set up helper from petitrc are opposite. Based in the XRAY Manual the FF should be higher than the FR so that the arms tilt down towards the rear of the car. The set up helper shows it as opposite... the FF should be lower than the FR. I also looked at several pro set up sheets and those that have anti dive have the FF lower than FR. So which is correct?

FF needs to be lower than FR to achieve anti-dive.

Or just add shim under the FR block and non under FF block..

I love how confusing the description is. Sounds like they described it backwards again.

Kick up causes more dive. Leaning the arm forward is anti dive. The opposite of rear antisquat.

I was going through the threads and this topic caught my attention.

From the Martin Crisp set-up guide; Anti-Dive will have the Front-Rear Suspension Mount [ lower ] than the Front-Front Suspension Mount.

I have the HPI Pro 4 chassis and its Anti-Dive help part had me confused.

That is pro-dive or front kick up. This will quicken the weight transfer to the front.

That is also what I thought. I tried it per the instructions thinking I was using Anti-Dive and it made the care very grippy it into corners and traction rolled on sweepers, made the rear end loose.... just screwed up the setup. I went back to level and will try FF higher than FR and test, regardless of what it is actually called... i think there is some inconsistency on the actual 'names'.

Try to think by yourself how the names are related to how the suspension is impacted... and it will become obvious

Upper hole (3 anti-dive): Works well in bumpy conditions, due to the constant caster angle when the suspension is compressed. However, steering is not as responsive as the 0 anti-dive setting.
Lower hole (0 anti-dive): Gives more aggressive steering when braking and especially while cornering, due to a decrease in caster when turning off-throttle.

That diagram, and the description is wrong. The line shows pro-dive (kick-up) as used on buggies, and that's what the explanation also describes.

Never used on a TC these days.

I do not own a XRay chassis. (I have a HPI Pro 4 and Tamiya TB Evolution 5) But the Anti-Dive set-up topic is interesting.
I dont run my chassis with Anti-Dive (at the moment). But now Im curious to test it out.


This is a Set-Up Sheet from a pro driver that used Anti-Dive (Front-Rear Suspension Mount [lower] than the Front-Front Suspension Mount)
