Ways to reduce tri pod mode?

Nasty Evolution · Oct 15, 2008, 08:03 PM

Looking for ways to reduce the car going into tripod mode while exiting sharp corners. (while on sticky tires at the track) Feels like I'm loosing so much exit speed while the 3rd wheel is in the air spinning.

Currently I'm on stock struts with Tien springs, everything else is stock for now.

Swaybar stiffness causes it but you said you are on stock bars...hmm!

Perhaps, spring length and spring rate....Check the BSP discussion thread, there is excellent info there!

soften the rear bar, stiffen the front bar or fix the rear dif.

corner entry and exit angle?have you taken any driving classes? i would love to take some classes and sharpen my driving skills.alot of this tripod action comes from the way the car is being driven through the corners.also jack your car up and push down on one side make sure the sway bar isnt stuck (salt,corrosion bushing too tight?)i dont know just thought i would toss it out there in case driver style is not the cause.thought about going to a full c/o setup? enjoy!

Coilovers will be added for next year. As far as the lines, it's a toss up. A seasoned vet and instructor who is a good friend of mine has the same problems with his EVO 8 (with ACD) He is in tri pod mode in just about every corner, through the Slalom, etc. His car is also stock.

Too soft Tein springs with sticky tires means you'll be lifting a wheel. Those springs are no good for handling.

Get rid of those, even if it means going to stock springs. I'd recommend getting a front sway bar.

Teins sucks, sorry man. Also like Drew said, if your using slicks you REALLY need stiff springs, preferabbly coilovers...stock suspension just cant get that stiff no matter what springs you run. Its really tough to run sticky tires on stock suspension because the tires are literally getting too much grip for the soft suspension and causing excessive body roll. That lateral G has to go somewhere, its all about good ole physics hehe.

Best bet is coilovers. If you want to stick with the stock type suspension (to stay in a certain class or what have you) I would consider taking the slicks off and getting some decent street tires like RE-01R's or Star Specs. It will really help you when you decide to bolt the slicks back up again too, sometimes they can be a band aid for other things.

Yeah the car came with the springs.. nothing I intend to keep. I bought a set of Stance GR+3 way coilovers and got screwed over. So till I get that resolved I will be on the Teins.

That sucks man. But no biggie on having to run what you have...I would just try running with your street setup rather then bolting the slicks on, you may even be faster

Agreed. There we Teins on my car when I bought it. First thing I did was take those stupid things off.

Even on street tires the car is lifting the inside rear wheel. On the Dunlops and stock Advans, and even on some cheaper tires I was running for a while. Coilovers are def on the way.

It could be done also by jacking the front spring rates up while reducing the the rear bar.

More rear travel with better shocks and the use of helper springs would also help somewhat. However, like cfdfireman said, the rear diff is to be adressed IMO to completely cure the problem (give TRE a call).

Like both cfd fireman1 and I suggested before, coilovers alone will not fix the problem so don't set your expectations too high on them because there is a lot more work to do.

^ Agreed....especially if you end up with coilovers with ultra short droop travel like a lot of them out there.

^^^Most of them out there, including some really respected and expensive ones
