STI flexible draw stiffener experience anyone?

[StraightOuttaCanadaEh]

I have so much grip through my tires that it's exposing the innate limitations of the chassis so I'm getting a bit of side to side suspension wiggle in the rear I think in high G corners and squats in depressions. Will try better coilovers first, but apart from that don't know if I need sway bars or strut braces. Also the entire interior now squeaks and rattles and I'm sure all of this can be mitigated with some chassis/suspension bracing

I don't know about the rear, the body design looks OK to negate the flex from the sideways loading of the tyres.

The front struts though, whilst very close to the fire wall, still have the typical sideways/cornering loading issues as all macpherson strut front ends, just not as pronounced as others.

The stock V bars help to a point.

I got a whiteline hinged bar as I still wanted some compliance to negate NVH, I put a fixed/solid bar on my MX5 and noticed alot more NVH, my Skyline had a hinged bar, it tightened up the frontend "alot" without undue NVH.

If your "becauseracecar" then NVH isn't going to be factoring in to this equation.

Opinions may vary

Personally I would buy whatever has been tested together with the other parts and in case it improves the behavior of the car even slightly. I've installed different performance parts from STI and every time there was a noticeable difference. In some cases the difference was apparent even after the first few days. Will the car go faster with a flexible tower bar? If a driver is professional, then in most cases I believe NO. The WRX STI 24h NBR car is a different case, because there is driver fatigue and even if it contributes to a few better laps it counts. Maybe such parts provide much more confidence to an ordinary driver, but in the end who cares? Our cars are supposed to be more about driver feel and not so much about power or time results. So a part that makes the steering wheel more direct I think that it counts.

A horizontal bar really only prevents the tops of the towers from flexing towards or away from each other, nothing to stop the shock tower from moving vertically.

If you have a horizontal strut bar, and hit a bump on the passenger side of the car, you will feel it on the driver side more than if you didn’t have that bar itself
