I just installed list night. Took all of 10-15 mins and is a GREAT addition to cornering. Yes, its in addition to the firewall braces, but IMO, these little corner pieces don't do too much by themselves. Its the easiest install in the world. No, you don't have to jack your car up! And no, there's no downside to this - at all.

If u put ur weight down on the center of the strut bar you feel it really flex, shouldn't it be rock solid to actually give you the rigidity required to corner better?

nope, it's not designed to resist loads in that plane.

it works in both tension and compression between the towers.

it's a relatively long piece so it'll be weak in bending (i.e. you pushing down on the middle of it)

I think a strut bar would be about the last suspension mod to make, after you'd already done swaybars and springs

strut bars can actually cause damage if you're in an accident where somebody hits your side (the other side can get damaged from the stress bar)

If you're looking to improve handling a stressbar would help the least behind sways, springs, better tires.....

if you're going hardcore and heading to the track or autoX all the time and running race rubber a stressbar will help prevent chassis fatigue over time, for most of us that's not an issue.

14mm extension didn't work for me, I had to use 15mm. Is this ok?

Can you fit both of them at the same time or not? do they fit at the same place? Which one makes more difference if only one is needed? cause i am thinking of getting one first and see how it feels
