3 additional tips for optimum deflection

1.) Shortening the Alu-spacer at the upper/front damper mounting 

to 5-6mm can increase the freedom to the (100%) steered wheel 

2.) Mounting the front dampers "with damper reservoir to the front“ ensures a largely unhindered 100% spring Kompression with an increased steering angle at the same time

Articulation with the crawlster®BTA2-TFL steering system

3.) Optional wheel-widening via 12hex eliminates any narrowness between wheels and damper – exspecially when using more voluminous tires
