Change front droop... i.e. more spacers on the shock shaft inside of the front shocks.

I run on very high bite rubber/foam track. I'm in need of stiffer front springs than the Xray 4-dot.

What other springs fit the XB4?

All big bore springs fit. Try yokomo yatabe springs or ae springs. Also have you installed 12 degree caster blocks yet?

probably answered in here somewhere, but what would it take to run the newer gear center diff instead of the slipper setup in my '14?

Xray 4-dot C=.080 equals 4.58 lbs

AE hardest spring is Purple at 4.2 lbs

Haven't found a chart yet for Yokomo springs.

You will have to convert the weights...

A lot of work, some drilling, cutting & shutting & possibly some different length drive shafts.

Easier to pick up a used '15 car.

I went through the Petit Big Bore Spring chart and wrote in the X-ray springs for my reference. The 4 dot rear is ever so slightly softer than the Yatabe Arena Black and somewhat firmer than the Durango Dark Red and Yatabe Orange. You'll see what I mean if you look at the chart.

Default XB4 12 degree caster blocks

Just bought a 2016 coming from a HB D413. I understand the 12 degree aluminum caster blocks is a must for astro setups. Can't find them anywhere except for amain.

Where do I find these?

Till they are back in stock what can I expect from the stock caster on high grip? Is it really that twitchy?
