Price per brace

Choose your length. If you need a length that is in between sizes, you can shave a touch off the ends to get where you need to be. Most chassis should allow for a slightly different length than what was supplied.

These are lighter than the typical Delrin cross brace.

These are stronger than the typical Delrin cross brace.
These are more rigid than the typical Delrin cross brace.
These have stronger threads than the typical Delrin cross brace, allowing for shorter hardware for even more reduced weight.

There is a significant difference from running a Delrin cross brace to an aluminum cross brace. You will be able to see your shocks doing the work rather than the chassis flexing and doing the work. This obviously makes for a stronger/longer lasting chassis since you will not be constantly twisting and fatiguing the chassis.

All of the above benefits from such as small and simple piece could possibly make these cross braces one of the best buys for one of these cars.
