I am having lots of problems with my 92 HB Civic. It has a b20vtec and is completly gutted. It weights 1975 lbs with 1/4 of gas and no driver. It has D2 Racing coilovers with 1232 lbs springs in front and 728 in the rear. I had softer ones but installed these springs to get rid of my tuisting (sorry for my spelling) problems. I also have Suspension Technique front and rear bars and skunk camber kits.

The car will twist on turns and will transfer all its weight to the opposite side. Drives me crazy. Any ideas?
Thanks
Jay

Opposite side front or rear? That set-up sounds like one understeering monster.

With your current setup your car should be understeering excessively. I would really check your alignment settings. You could have excessive toe out, either in the front or the rear.

swap front springs to back, vice versa

 

The car will move all its weight side to side. The car on a fast turn lowers some on one side and raises on the other. I tried installing harder springs (1232 front and 728 rear) but the problem still there.

You mean weight transfer? Cant get rid of it, sorry.

 

There has to be a way. There are some Civics at the track that stay planted to the floor, take turns really fast with minimum weight transfer from side to side, My car has too much weight transfer and does not allow me to take turns fast enough or have to wait a longer to get on it after that turn.

What he said! FWD demands set up tricks that are very different from RWD. Try some searches, this has been covered a lot.

 

You're confusing weight transfer with body roll. Weight transfer will be there unless you change the track, weight, CG height, or speed of your car. Body roll, you can eliminate by changing your roll stiffness (stiffer springs).

I am pretty surprised that your car has so much body roll with 1200lb front springs.

Impossible.

The same car will have the same weight transfer no matter what. Newton 0wnz j00!

sounds like understeer, which is what everyone else is suggesting could be your problem due to the very stiff front springs.

have you changed your bushings? They are probably worn after 14 years.

I'm sure we could come up with some gyroscopic device to keep weights even... Sounds like a fun project actually!

As has been said, your spring rates are pretty freakin' bad. At the very least have them even f/r, but I'd definitely go higher rear than front.

Weight transfer is a function of weight (d'uh), Cg, wheelbase and track width.

I know this... we could come up with something to counteract the weight transfer of the car... Ever read up on the segway?

 

I heard there was a plug in module for the new ASGM that incorporates a "weight transfer minimizer" program

 

What size sway bars do you have?

I would also say replace the bushings, and get some stiffer rear springs.
Definetly check the bushings

 

This is what the cars does.


I have suspnesion Technique bars. The bushings are all new. Right now I have 1200 springs in front and 730 in the rear. What do you think is better, installing 1000 in the rear and keeping the 1200 in the front or should I install the 1000 in the front and 1200 in the rear?
Thanks

 

Are those shocks valved properly for the spring rates?

Put the 1000lbs in the rear to start with (leave the 730's up front) and then go from there - try swapping in different rates, see how it feels.

Did you get the ST bar that was made for cars that didn't come with stock front sway? or did you have a front sway and just upgraded?

Did you put in poly bushings? Rear trailing arm bushing?

I agree. Also does the car react this way all the time? i.e. slow corners, fast corners, etc? It almost looks like you are pitching the car..... Have you tried different lines? What are your camber settings?

didn't think about that... d2 racing? probably not.

 

The car does does this in every corner. The camber settings are:

FL -3 FR -2.5
RL -1.5 RR -1.5

Whats wrong with D2 Racing? I don`t know much about them.

You may want to find out if the shocks are valved properly for the spring rates you run.

If you send them to CRX Lee @ Koni he will dyno them for free.

Are those camber settings done with you in the car? What about toe?

A sub-$1000 coilover setup from a company in Taiwan? I find it hard to believe they're valved to handle 1200lb/in springs...
