dirt/clay setup

[grelland]

Guys.

Winter is here, and our astro-track has gone into winter-hibernation.

But just one hour from here, a brand new indoor clay/dirt track just opened:



and I was wondering if anybody out there has any experience with setups on similar tracks.

The track is fairly new, so the grip is not that good yet, but I expect a blue groove to develop.

I have had advice to increase the anti-squat, and bring the motor as far back as possible. Any other tips?

I still have not tested the track, so I do not know how well/bad my astro setup works...

[grelland]

not that many people running on clay tracks, I guess...

Well, I had a chance to test it last weekend and it worked ok, but in general the grip is quite low in places, and all the 2wd cars struggeled...

My biggest problem was the short distances from the 180 deg turns to the jumps, and I simply could not generate enough forward grip to clear the doubles... Other 2wds struggled too, but some of them made it, so there is more grip available.

Any hints?

Thats what we need over here. Looks amazing.

Is this on an RB5 version?

If it is are you running in the additional inside hole on the wishbone? This will give more drive. Also stand it up on the tower.

Run the inner rear ballstud on the lower row of holes.

Remove weight from the front and shift to the back. You can add about 20g either side of the motor.

If you are on small bore shocks try black rear springs. I ran these most of the time on high grip too but it will give more grip.

Make sure the rear driveshafts are level.

Short wheelbase if you are not already.

This is probably where you'll tell me it's not an RB5 but the same rules will apply anyway!

Raise the gearbox....

Rudebits may be able to help you with that.

If the car is B4.1 vega, convert it back to original rear motor B4.1. It works better in low grip clay. I use B4.1 at summer, vega at winter on astro, carpet etc....

my experience shows that minor traction advantage short base might give doesn't justify loss of steering in 180 degree turns.
I went back to long base and was amazed how easier was to drive the car in U-turns.

Short wheelbase will give a fair bit more drive, not just becuase of the weight shoft but because of the driveshaft angle too.

On low grip I always try and get as much drive as possible and then get steering back in other ways. Short wheelbase will pivot in to the turn more, but will give less steering on power so it just depends what you are after.

If you are struggling to get up to speed for a jump due to lack of traction (like grelland), then short wheelbase is going to help.
