I have an integra 4 dr (DB7) and am looking to improve handling. I've already decided on koni yellows and ground controls for my shocks & springs. This is my daily but will be used for some road racing (time attack).
After some extensive research and reading, I've come up with the following:

LCAs- Do nothing, just shiny pieces of metal with new bushings. Better to invest in some new hard rubber bushings with OEM LCAs.

Subframe brace- Useful only if used with a 20mm+ rear sway bar.

Beaks lower tie bar-better off going with a subframe brace

front solid shock tower bar- gives better steering response

Front sway bar-usually causes more understeer depending on spring rates.

Sticky tires-essential for high speed cornering

My question is if I get high enough spring rates (ie 450lbs or higher), will a 20mm+ rear sway bar still be beneficial on a street car?
Any chassis or suspension pieces I'm missing that would complement konis/GCs?

 

For those with cars that don't come factory with a rear sway bar or LCAs with endlink mount locations, aftermarket LCAs do serve a purpose more than bling. Some also offer better endlink positioning than stock LCAs. But you are right, you can get better bushings for your stock ones if you want.

For your question, the rear bar and it's influence will depend on the spring rates for. Oth front and rear. You told us 450+# springs but where? Front, rear or all around? Need to know this first.

If you actually plan on seeing any track with this car, just go to the track and start learning your car. Then start building the suspension for your needs and driving styles.

 

Not sure. Thinking 450f/500r to compensate for a lack of a bigger rsb? Thoughts?

Any other worthwhile parts that would stiffen up the chassis short of a cage?

 

there are unlimited amount of suspension setups that have been proven to work well with our cars. weather its a jdm front bias or a typical American rear bias setup. but in the end its your car that your driving and you need to build your setup to compliment your driving style. for now your money will be much better spent on track days. learning your car and getting seat time. then once your suspension is the limiting factor that is slowing you down, rather than your skill as a driver, you can start to build a suspension setup that works for you. have fun!

 

You forgot the upgrade that makes the biggest difference, seat time.

Sounds like you're trying to run before you can walk.

 

Bushings might be a good idea, considering the age of our cars. I personally went with Hardrace and like them but, the other choice would have been OEM.

 

aftermarket lca weight difference can make a difference because of unsprung weight, so it technically does not not to anything

 

you could cut water weight for a day and lose more than what you gain by running aftermarket LCA's
