I fitted mine at the shop yesterday however with ZERO issues. Followed the instructions to the letter on level ground and everything lined up. Retained my camber settings (-2.5) and everything sat flush and fit. The only thing is the clearance to the hard-line (on top of the engine) being negligible. Not sure what kind of impact that's going to have in the long run, but will monitor. I'll take shots when I'm back from the long weekend. My fitment could also be because I've only got 11k on the ODO - still quite new. I expect it's the same reason I don't have 2-3mm of space under the hard line - no engine /motor mount sag. I fully expected the intended effect of this bar to be small or muted at best (as per OEM bar). Couldn't be farther from the truth. TOTALLY tightened up the steering and front end. Never thought it would be possible on a car with a torsional rigidity of 32,000Nm. Awesome purchase. Next rack day Sept 10. |

had to clean ICV, DISA and throttle body so a friend helped me out (I have no tools). Removed the Race Brace and re-installed correctly per RE specs...Took pictures of the work done by RRT to custom fit too. Sorry for the HUGE delay, but better late then never...

The torque in the chassis around it's axis is still reacted to the ground via the strut towers and springs and the forces are reacted through the brace via the three mounting bolts on the top of each strut tower. So although twisting due to driveline torque or deflection due to suspension loading may both create load on the brace via the towers, the stiffening effect of the brace stays the same.

Aerobod, I think u should install one of these and THEN share your experience. There's a distinct before/after difference. It's a great piece.

From a chassis rigidity perspective, triangulating from the middle of the brace to the point where the bottom of the strut tower meets with the lower reinforcement would bring great benefits but is not very practical due to the engine being in the way. From the perspective of the brace doing anything other than keeping the distance between the strut towers fairly constant, you just have to look at how easy it is to lift the free end of the brace by hand if it is only bolted to one tower, to realize it isn't much better than a pivot where it is attached to the top of the strut tower. |
