Sounds good. How does the roll centre settings affect the handling? Is there an online shop thats carries them?
Jimmyd - The IRS adjustable caster blocks for 1/12th scale have 4 mounting locations for the upper arm/caster block pin to adjust roll center. Modifying the roll center will change how fast the front transfers weight side-to-side when entering a corner. It allows you to tune how aggressive the car reacts on turn entry and to tune the steering response through the center of the corner. The adjustable reactive caster rake helps tune the steering response from mid-turn to turn exit. This is accomplished by keeping the same initial caster for turn entry and adjusting how much the caster reduces as the suspension compresses.
I don't buy much stuff online but I'm sure
