Suspension Bottom Out
Along with my carburetor problem, found here, I have an issue with my suspension as well. I have a Hpi Nitro Rs4 3 18ss (that's a mouthful), and I'm not too sure why I've been having problems, I've built two hpi kits prior, but this one being the first nitro...On the highest settings, my chassis scrapes the ground. I have spent hours trying to adjust suspension but have only found out how to make it lower, which is bad right now. Any rs4 owners that have had the same issue? I still need to get the engine running so don't worry, I haven't been running it with the chassis scraping the ground

You shouldn't be having any problem with ride height. Double check your shock lengths with the instructions. Also make sure that the shock mounting locations are correct.

I have excess space in the shocks where the springs do not fill up, I would need to shorten the length of the shock to make it flush with the spring...wrong size springs maybe?? I can't thnk of anything else

There should be plastic shock inserts (collars) tha come with the kit. Use them and your problem shoud go away.

Yeah I know, but there's only 1 inserted into the 2 front shocks in the manual, and I'm gonna need like 3 at least...odd?

Check the part numbers you used in building the shocks. You can also check the part you used against the parts size reference along the margin of the manual.

RS4 has uneven weight distribution. the engine sits on one side and when the car takes a turn leaning towards the engine the chassis will scrape no matter what you do with the suspension to prevent that from happening,if you do managed to stop it from scratching most probably your suspension has uneven setting between both left and right in the end. Increase ride height and you will experience roll or unstable cornerin due to weight shifting.
To counter the problem I had on my RS4, I bought an MTX4

haha nice solution, unfortunately that's not what I wanted to hear considering I haven't run this yet

or 2. use Longer boots ( the black plastic that clips to suspension arms ).

yeah I'm thinking that it is the boots, because they have longer ones in the kit than the ones I have on currently, I'll try that when I get a chance, thanks

They are from the kit! haha they're the part that HPI tells you to use that's why I'm confused in the first place...would the amount of oil in the shocks have anything to do with it? Cause at one point I had the o-rings in the wrong place haha and I lost oil
