Schelle Racing : B64 Carbon Gearbox Shims

 

The Schelle B64 Carbon Gearbox Shims package come with 2 pcs. 1mm thickness carbon fiber shims.   These shims fit in between the B64 gearbox and chassis and raise the gearbox and suspension mounts up higher as a tuning option.   Almost all “team” setups use this option to raise the rear gearbox to carry more speed through the turns.

 

Features:

 

1. 1.0mm carbon fiber, made in the USA.

2. 2 pcs. included to tune 1mm or 2mm height change.

3. Strategic cut-out to prevent backwards differential installation. 

4. Package comes with Instruction/Tuning notes, 2 pcs. 1mm Carbon shim.

5. Works on rear suspension only.

 

When to use: 

• Raises the inner suspension pivots 1mm higher when using the same ride height (stack 2 for 2mm).

• More support in turns and a higher roll center.

• Makes the rear more responsive and more entry and mid-corner steering.

 

Installation:  Remove all 5 gearbox screws from the chassis as well as the rear chassis brace screws.  Slide the shim into position on the chassis keeping the open side to clear the diff.   Re-assemble.
