its noticable when making hard corners, feels like there is less strain on the car when turning at a little higher speed. i felt a difference after installing it and felt a difference after installing the rear strut bar as well. not much but there is a slight difference.

 

nope.

14.8.L

Strut bars are permitted with all types of suspension. Strut bars
may be mounted only transversely across the car from upper
right to upper left suspension mounting point and from lower
right to lower left suspension mounting point. No other configuration
is permitted. Additional holes may be drilled for mounting
bolts. Only bolt-on attachment is permitted. Interior trim panels
may be modified to allow installation of strut bars. Holes or
slots may be no larger than necessary and may serve no other
purpose. This does not permit any modifications to the frame or
unibody beyond the allowed mounting holes.

the autoexe front and rear strut braces sure are pimp though.

 

So could a person have the two separate bars to stay in compliance?

 

i don't think so. i'm not a rules wizard, but the way i understand 14.8.L is that a strut brace, either front or rear, may attach to only two points and must be either at the top or bottom of the suspension mounting points.

 

If that is the case I would definitely do the Mazdaspeed one over the Greddy.
