Default Downtravel, what's a good starting point?

What's a good starting point for amount of downtravel?

I'm running in stock class, carpet (with a few small bumps), rubber tires and a HPI Pro2

I know for sure the info already is on this forum, but I couldn't find it

I would say 2mm "real" droop all round as a good starting point.

Get some foams for carpet. Save your rubber tires when playing outside.

Cole Trickle;

Usually for outdoor Asphalt, my Cars work better if I run full droop.

Since the traction on Carpet is so good, you may need to limit droop to get the fastest possible lap times.

Start with 4-5mm in the Front and 5-6 in the Rear. This will make for a very stable Car and you can always take some out later if needed.

Some tracks are rubber only and some are foam only. It all depends on where you are.

That's right! I remember seeing Rubbers on YOUR Car the last time you were playing outside.

Hope Nate left some parts on the Car when he gave it back to you.

We're only allowed to use rubber.

Today I went from approx. 5 mm downtravel to 2. Way more responsive, yet good grip AND stable. Actually, it's very stable during cornering.

However, the rear tend sligthly to (very sligthly) to spin a little out. I think I try 3 mm all around next time.

Thanks for your help.

Could someone clear this up for me?? My droop guage looks like this:

I would have thought more droop would have meant longer shocks or more down-travel. Using a guage like this it is actually the reverse????

So what is the different between those two? I know what a down stop is..

A good starting point is to have front and rear the same... AT WHAT NUMBER?? Just be sure on Max droop, the spring still being hold firm enough with its collar and end cup. That's the starting point!!

It's a bit confusing innit John?

Strictly, more downtravel IS more droop.

The gauges are made in such a way that more droop is actually a smaller number.

I suppose it's a result of them referencing from the bottom of the chassis - it's easier to use that as 0, than to use it as 10 and then count down.

As long as people don't confuse "gauge" measurements with "real" measurements, and state how they are measuring it, there shouldn't be any confusion

Cheers Sosidge!

That's what I thought, but as you say it can be confusing.
