TT-02B suspension setup

[skom25]

Hi,

In a moment I will start to assembly CVA shocks for my TT-02B.

I bought shafts, so I can use pistons with holes. I also have red O-rings.

Car will be used on hard surface like concrete and asphalt. I found that I prefer low but quite soft suspension, so body can roll a little.

I have few questions:

1. Which pistons I should use at start? How many holes?

2. Which oil?

3. I am interested in #53927 springs set. Is it worth to buy them?

4. Should I build shocks with full travel or add spacer inside to make them shorter?

I considered DF-03 shocks but they are super expensive and I think that in my case, I will be waste of money.

A good starting point should be 3 hole pistons and 400 oil.

I can't speak for these springs other then offering my usual run-the-stock-ones-first advice.

Internal spacers are intended to reduce droop. If you're not sure how that all works leave them alone. If you want to experiment for an asphalt setup I would suggest 6mm ride height (can you go that low on this buggy?) And 2 to 3mm more for the droop, meaning the tires would start lifting off the ground when the lower deck is 2-3mm higher than your ride height. Later you can experiment with more droop at the rear than the front and so on. Droop is a very powerful tuning parameter.

Have fun!

Agree on 3-hole, rebound will be quicker and pack lower which will be a benefit with the limited suspension travel of the stock tt-02b.

personally I’ve always found that 4wd benefits from a tad of understeer, and usually go for 5wt thicker oil in the front shocks. Depending on your brand thats 50-75cst.

Thanks!

I have 400/800/900/1000 from Tamiya.

Can I mix 400 with 800 to get 600?

I am not sure if I understand correctly. If I use 400 on rear, I should go for something like 300/350 on front?

Other way round.

stiffer damping on the front
