Now in it’s 3rd version this product is now precision CNC machined from 6061 T6 Aluminium and beautifully finished in Thumbs Designs trademark Orange anodising with a stylish silver chamfer around the top edge. The precision machining means that the bearings are a perfect push fit into the metal counter bore in the rack.
The Thumbs Designs Aluminium steering rack is a direct replacement for the plastic kit item with the major advantage of being made from a high grade 6061 T6 aluminium so it will not flex like the kit plastic one. By removing the flex in this part you will notice more positive feedback under high-speed cornering as the Thumbs Designs drag link does not bend and allow the ball studs to deflect. It has also been noticed that the car has a more composed and consistent feel to the front end grip, especially when landing nose first or landing heavily from a big jump.
The Thumbs Designs aluminium drag link also benefits from having 2 extra holes cleverly positioned to give you 4 possible tuning positions for the steering control rod mounting ball. The extra positions will aid you to adjust the ackerman angles of the steering geometry which will fine tune the way your car turns in and grips through a corner.
Of course you could just use the standard kit position which is the furthest forward option.
