The T1R X-brace is a strut tower brace that has a lower x member that ties the tops of the strut towers to the steering rack on the Honda S2000. This brace effectively locks the front of the chassis which sharpens steering response and feedback.
First, park the car on level ground, raise the hood and remove the intake box by removing the bolts and clips around it’s base. Now locate the two bolts on the steering rack and remove them with a 14mm socket. Next place the cross member of the x-brace in position over the steering rack and use the two bolts to secure the cross brace to the rack.
Removing the intake box isn’t required but it takes literally 1 minute and will give you much more room to work.
Remove the circled bolt and then follow the arrow along to rack to the identical bolt hiding under the solenoid in this picture.
Next remove the two nuts from each strut tower and then place the strut bar over the strut mounts. A little whack with a mallet on the top of the bar can help get the mounts to sit right if they won’t go on all the way. Now tighten the bar to the strut mounts by reinstalling the nuts onto each strut. (See pics below) Once tightened, use the supplied bolts to attach the cross brace to the strut bar and then tighten everything down. Once don, reinstall your air intake and go for a spin.
This images illustrates how everything mates up.
