Xray xb4 2wd help!

[Blitz34]

Hi, just got a xb4 2wd from mb models just wondered what hopups or essential parts are needed before I bulid thanks.

The only essential part is the alloy covers for the cvd's as the plastic ones are a weak spot. Kit springs are ok to start if running indoor - if outdoor then we use AE springs front and rear

[Blitz34]

Thanks, seems to be alot with alloy shock tower protectors is that just precautionary?

[luniemiester]

I've only ever used the silver protectors that came with the car - indoors I do use a lexan guard in the front tower at the request of the club but I've had my car 12 months and broken nothing and that's racing indoors at silverstone and outdoors at regionals and on 1/8 scale tracks. The cars very durable IMO - just make sure you seal all the carbon fibre parts with super glue like the manual says too.

What AE springs do you use outdoors smd why?

I personally didn't bother with the AE springs. They are good if you want a bigger range, however I found 3dot/2dot front and 2dot rear worked everywhere.

We use the yellow and purple up front and green and white rear. We liked the feel of the AE springs better outdoor as felt more progressive than the XRAY springs did (tried XRAY progressive springs but for the 2wd car I found them very inconsistent )

If you run AE springs we also run 2 hole Pistons 1.6f 1.7r with 35-40wt oil up front and 25-32.5 rear depending on the grip in the track and how big the jumps are.

If I run XRAY springs then I run the kit Pistons front and rear with 40wt f 32.5wt r
