xb4 2014 very bumpy and wet astro set up

[alex97]

hello
After my first run with my xb4 I was a bit disappointed with how it was. I was using green mini pins that ive always used and they work very well on my b44.1 avid. The first round was terrible I only got 7 laps and I usually get around 10-11 in the first heat when the track is wet. I did take all the flex chassis screws and that did help a lot but the car was still not as good b44.1. is there any thing that I can change to make it drive any better.

thanks

It would help if you could post your current setup so we have an idea what you using at the moment. You don't mention why its not doing what you want compared to your previous car?

Shock oils, pistons, springs, diff oils, roll centres to start

Nothing is as easy and forgiving to drive as a B44!

Did you set the slipper right, as I assume you will be running kit setup.
Too tight a slipper and it will be an animal in the wet.

I find that no roll bars / 10K oil all round / shock middle on tower / inner on wishbones (max droop) Kit pistons (40 oil front) (25 oil rear) and it works a treat. Never run greens though these days, Yellow's always or Balistic's if it's wet outdoors.

Think it may take you a while to get happy with it, something must be very wrong to go from 10/11 laps to 7. Maybe flog it to me and cut your losses

Thanks Andy. I never built the kit I bought it built but not run off of this forum so I DONT know the current set up but it has stock everything. There is another xb4 where I race and his car felt much nicer than mine so I may see how he set his up.

What tires do you use in the wet ?

Ballistic Buggy Greens if it's really wet.
Damp - New Yellows.
Also D-Boots are quite good as a backup.
If it's pouring down / muddy, on grass - TR32's are ace but rare.

If you did not build the car - I would strip it down and start again to be sure it's right

Currently running 10k/5k although going to up the rear to 7k or 10k.

Had a Durango previously and ran 10k/10k almost everywhere other than wet grass or RHR dirt.

Surprised that anyone can notice a difference between 7k/7k and 7k/5k, I only notice a difference if I make a bigger jump in oil. I think some of it is placebo.
