Buggy chassis tuning
Hi again everyone, well the second hand car and all the spares I bought have arrived, and it is time to start trying to tune it for me and my local track.
Between the cars I have and the spare parts I will have 5 sets of front and rear shockies, what combination oils and holes should I build?
My local track is what I would consider tight and quick (not fast as no really big straights), it has some sweeping bends with a couple of hair pin corners, but it gets very rough and has low traction apart from when it is watered down.

There is 1 large jump.
I also have a large array of different colored springs, what is recomended?

Also the car came with a large assortment of sway bars both front and rear, what should I fit? and what will the car do with the different bars?

I was emailed some setup sheets so will work off these.

In the spare parts there was a 43t centre diff gear, is this different to standard? and if so what benefit would this have as opposed to standard? (trying to see if I should fit this)

Also there are a few different brake rotors and brake pads, some rotors have what I would describe as cooling fins cut in them, and there are some pads that are material and some that are steel, what should I fit? The brakes do get used a fair bit on the track.

I am basically looking to rebuild it (replacing diff oils so I have a known quantity) and am just trying to figure out what is a good starting point.

I realise Xray oil would be the best for the car but will struggle to justify the cost.
I was thinking of getting something like this

Or are these no good?

And for diff oils.
is it ok to use this brand as opposed to teh higher costing Xray oils?

Thanks in advance from a total tuning rookie, if there are any threads that I can read that will help me in understanding please direct me to them.

I'd use that set up for your baseline to get you started. I have no experience with x-ray but at least that is a start.

On my jammin x2 buggy I use...

Shock oil = Losi
Diff oil = Accociated

If that helps.

As far as the breaks I use the avid-rc breaks. Find something in what you have that won't fade on a long run or when fuel gets on them.

Looks like the 46 tooth is the stock spur gear. I'm not sure you may want to double check. Again I have no experience with Xray.



Read through some of those and learn what things do. Find something drivable and practice practice practice.

I could use some practice myself =P

Hope This helped.

Shock and diff fluids are not "brand specific," use what you want. Sometimes they vary from standards just a bit, but not much.

And it might help if you told us what kind of buggy it is... :nod:

From the pics, it looks like an XB8. I had one of these and if you put 7k/7k/1k in the diffs, you WILL have your hands full. I think I ran 5k/5k/5k in the car and even then it was twitchy. In terms of durablity, that car was TOUGH! Turns great too.

Sorry for the late reply everyone, I was dragged away from internet access for a few days with work.

Yes sorry, the car is an XB8TQ.
