Option Part Tip:

Useing a steering block from an Yokomo Chassis on the Roche F1 Evo. The Yokomo steering block have a really nice goodie. You can run these arms in two ways. One way is the inline axle mounting and the other one trail axle mounting with a difference of 3mm between the inline Mount. The inline mount is exactly like we have it in the kit from the diameters. One small modification was needed to use them. Under the steering arm you need to use a 2mm shim instead of 0.5mm shim (check ride height after this). Rest fits perfectly

Trail = axels slightly behind center of pivot
Inline= center of pivot

Inline axles give better turn in and more responsive and aggressive steering. Trailing axles reduce response so steering is smoother and car is more stable and easier to drive
