how would i be able to get better traction through the turn? My current setup im running is a 91 integra with a jdm b16a... my suspension is the energy suspension hyper flex kit and the apexi ws coilovers. I have the suspension techniques rear sway bar. Im running hoosiers when i run at autocross. My problem is when i am exiting a turn and trying to power out of it i just get wheel spin. My rpms shoot up and finally when i make the wheel straight again the rpms drop and finally catches traction... my question is what is the next mod i should do for this problem?

What size is your rear swaybar? What size is your front swaybar? What springrates are your coilovers?

LSD will help a ton. Putting the softer springs from the coilovers in the front will help some. Rear swaybar will help some.

FWD chassis is easy to figure out. "Any weight on the inside rear could have been on the inside front". Get more weight on the inside front and you're gold

G'luck

 

In no particular order

LSD
Less front spring / ARB
More rear spring / ARB
Non-binding bushings (I know DC RTA bushings bind when poly, do DAs?)

 

thanks for all the input guys... appreciate it... im running the stock spring rates on the world sport coilovers. My front sway bar is stock size and the rear is the ST sway bar... 19mm i think... correct me if im wrong...

tunernoob...
idk if the poly bushing bind? what is bind? haha im a noob...

anyways looks like i might get lsd... any suggestions on what lsd... im only doing auto cross down here and daily driving this car... thanks again for the input!

 

I'd try disconnecting the front sway bar for a run or two to see if that helps. It's free.

Poly bushings do not flex the same as stock bushings do. Again, I've never actually taken the time to look at the rear suspension of a DA, but if its similar to a DC, then you need more flex in the rear trailing arm bushing than a poly bushing will allow. As the suspension moves through its range of travel, the trailing arm moves in and out, relative to the chassis, as the camber changes.

Then again, binding rear suspension could create snap oversteer, and should be relatively easy tp notice during autocross.

Also, if you're running in STS, then an LSD will bump you up to STX. Personally, I have enough trouble keeping up with the STS Civics, and don't feel the need to go play with the STX Imprezas.

 

hey thanks for the explanation... yes the rear arms are almost the same as the dc integra type. =/ im in dm right now...

any suggestions on what lsd to run...

If you haven't done any crazy mods like lexan windows, or gutting your interior, you should probably be in Street Modified.

 

i don't have any crazy mods but i do have an engine swap... thats what put me in dm... b16a to be exact....

 

If all else fails, try dailing in less power... (power oversteer) You might end up sacrificing to much time to get on the power a fraction of a second earlier. like nonsense said try without the front bar and see how it feels, pay attention to your speed when you're on maintenance throttle.

 

-LSD
-Softer front (soft spg, no sway bar)
-Tigher rear (&lt;-- That don't sound right)
-If you have more than 150+ whp then a traction bar will also help plant the front

How'd he get that power oversteer again? The new Mugen "program-your-own-physics" chip? Maybe you meant power understeer..
Yeah, driver definitely makes the car's ultimate behavior. My cars will understeer or oversteer on demand based on driver input. Well, my durango "mostly" understeers, unless I'm really being an ***..

Please explain... Not sure what a traction bar will do to the understeer/oversteer traits of a car.

you shouldn't be in DM as Jaker said... go to SM, reading the rules to properly classify is important. If there is some trivial mod holding you from SM change it back.

 

LSD will make a huge difference, I would do that first it will allow you to better examine your suspension set up.

His question is about traction. I noticed after installing my Full Race TB the front end of my car had way less flex. This improved braking stability, straight line traction, and keeping the wheels planted in turns. Not my first recommendation, but my car feels much better with the traction bar.

He'll be stuck in D mod (maybe prepared, don't know those rules really well) if he goes with any of the aftermarket front crossmembers/traction bar setups.

Like vworcivic said, you should read the rulebook. You are likely classed in the wrong class. Have a look here at the classifications. Section 16 is the part that applies to you. If you have any questions, you could always list all your mods here, and we could help you to make sure your car is legal for Street Mod (swaps are allowed, and more).

thanks for all the replies guys... after christmas hopefully lsd... looking to pick up a kaaz or maybe even a quaife...

SM???? hmmmmmmm

what i have is B16a engine with i/h/e... dropped on apex ws coilovers suspension techniques rear sway bar... poly bushing kit from energy suspension... interior two seats one bucket one reclinable corbeau... no back seats! maybe thats why im in dm maybe... not sure... front and rear strut bar... and hoosier slicks... can i still be in SM with all of these mods? that would be alot better instead haha

 

If all you took out of the back is the rear seat and the carpet attached to the seat, then based on your mod list you're Street Mod legal. You can also take out the spare and jack (I think thats legal for all the SCCA Solo 2 classes) and the plastic/cardboard panel that covers the spare, as well as the rear seatbelts if you want to go to the trouble.

 

thanks jaker

anyone else.... opinions on an lsd? im thinking about kaaz... something that will fit a b16 cable tranny

 

If you've got full-on slicks, those probably would bump you out of SM. Don't you have to have hard-compound tires to be in SM, ST, or STS? Hard-compound tires would be things like the Falken Azenis, not "DOT-R" tires like the AS06 or whatever the latest autoX tire from Hoosier is.

My advice: Tighten up the rear suspension. Stiffer springs, more rear bar.

Kaaz == craap (for RR/AX), IMHO. Quaife would be preferable...

--DD

Sadly, I'm thinking more chassis flex in front will keep more weight on the inside wheel But it would surely give more controllability.

The OP needs less front roll stiffness, more rear roll stiffness, and an LSD for sure

 

i have never heard kaaz and crap together.

 

alot of my friends are saying go with quaife... its the same price range as a kaaz... idk guys =/
