Body flex

Sup guys. So when I do a good turn or a sharp turn I hear a creek in the back. I`m pretty sure it`s body flex and it`s annoying. Would a rear upper tie bar eliminate that? or a lower tie bar? Or both. I always thought of strut bars as more for looks rather than performance but I know that it makes handling and the car more stable sapposibly. Anyone who has this on ther car vouch for it? That it actually does improve handling. I don`t car about looks especially if it doesn`t improve handling. It`s like a carboard box if its open it`s weak and if you close it up it becomes more stable and firm,. Atleast that`s what a Honda tech video said. I`ve seen some nice Megan tie bars on ebay for like 70 bucks. They look pretty sturdy. Any other good brands that are not to pricey.

Icon1 Professor Driver gives his view on the subject

How much stress is placed on the rear body and suspension components in the rear of the car to a large extent is proportional to the weight and/or effective weight on the back of the car as you make a turn. A front wheel drive car does not have much stress inducing weight in the rear to create much interia during cornering. Also, unless you have a ATTS Prelude, you can't really use much of the engines torque to cause a torque on the center of gravity of the car to create a stress inducing , effective transfer of weight to the rear when cornering.On a fwd car one usually tends to apply the brake in a corner to lighting up the rear , make it effectively lighter, so as to make it easier to bring the car around using the brake, turn ,accelerate technique.Weight transfer is also done using trailing throttle over steer where the engine braking acts to lighting up the rear and makes the car want to come around.So in many cases on a street driven, non drag type, car those strengthen enhancements to the rear are just eye candy and not really needed . If you want to strengthen something on a fwd car , a front strut bar is the way to go because thats where all the stresses are coming to bare on a conventional fwd car.

Re: Body flex

I've heard they're essentially useless and then I've heard it's like a new car. I guess it really depends on how accurate your butt dyno is. Roll cage will stiffen that bish up for sure.

Re: Body flex

SHDRIVER, why do you have such a supremacist like bias towards your particular trim of Prelude. Are you trying to say the the owners of all other Preludes own inferior cars? From my understanding the ATTS system is an electronic lsd and nothing else.

A front strut bar, and sway bars would be the most noticeable things to grab.

Re: Body flex

Hey SHDRIVER are you like a english teacher turned physics major that happens to be into Preludes bc everytime you post its very over the top with details. I feel like im at school when i read your post. or do you just google it and copy paste? no matter what you do, your putting the information out there and making it easy for the rest of us. lol so for that i thank you...

And to solve the body flex just get a rear strut bar. it will help bc your suspension cant take all of the load while cornering so the frame of your car flexes to releave stress from the strut towers. and if you want to strengthen your cardboard box further, get your self a good lower tie bar and maybe a thicker rear sway bar.

My front and rear strut bars do well and i bought the cheap brand.
megan parts will be more than good and stylish

Re: Body flex

Alright thanks for all in the input! Including SHDRIVER haha Yeha I`ll most likely go with Meagen because Tanabe and ob and etc are more and I can`t find them on ebay ._.

I feel my BB1 is superior to the S and Si models, lol.

Re: Body flex

I recently upgraded my stock rear sway bar with a Tanabe sway bar and it has done wonders for my body flex. My car is so much more fun to drive.

Re: Body flex

I put a Neuspeed front strut bar on my '00 right after I bought it and it made a huge difference. I later bought a Tsudo double bar upper rear strut bar and it seemed different, but not a lot. I had the struts replaced last year and the numbnutz dealer mechanic couldn't figure out how to get it back on. I didn't realize what a difference it made--and I was used to--until I drove it without it. Needless to say it's back on. I've never had any experience with the lower bars.

The famous SHDRIVER! I've heard so much about this guy! ..and I kinda see why..
Amazing how all that typing yielded no technical terms. I don't know much about ludes or cars in general yet, but I know my physics. I'd go with a stiffer front suspension, add weight to the back, and damp out the back to gracefully relieve the stress coming down on it after you've been torquing the front.
Why not try to reduce the pressure on the back tires so that you get better traction and rear stability (more surface area in contact with the road)?
Wish I could help some more, let me know if there's flaws to my logic. Don't know what components will fix the problem, but that's what you guys are here for!

Re: Body flex

Front chassis stiffness is 10 time more important then the rear. Unless you are on some super sticky tires or crazy spring rates. You do not need to stiffen the rear part of the chassis.

That makes sense Dwend. Thank you both A rear wheel drive car would most likely benifit froma rear sturtbar then

Re: Body flex

Yup yup SHdriver is on point with the detail! Kudos man!
And I noticed a diff with my sway bar and front strut bar on the 5th gen. Definitely feel it in the corners they hold alot tighter.
