I have noticed that when I go to the track with the stock suspension that it really beats up the outside edge of the front tires. This generally indicates that a little more negative camber is required.

As I only track my Evo occasionally I don't want a track alignment as it would be really hard on tire wear.

Would it be possible to use a set of camber plates to temporarily adjust the camber while at the track and then return it to stock when done? I have done this with my old race prepped 911 to fine tune the suspension at the track but have never done it with a street car.

My concern is what effect this will have on other settings such as toe?
Has anyone tried this?
Which camber plates are easy to adjust and will work with the stock suspension?

Thanks for the input,

 

theres a shop in N.Cal that did my Alignment, Corner Weight, and also ride height. Once i think of the name ill give you guysthe name!

yeah, that is possible.

ofcourse when you adjust one part of a dynamic system it will affect other parts... but.... not reallly that big of a deal.

Just get some camber plates, if they dont have marks on top off them just mark where your 'street' setting is and when yuo get to the track just set the camber plates to as much negative camber as possible (without going over board). When done just set it back to your street set up. You'll love it!

not sure on who makes/sells camber plates individually as I got mine with coilovers.

 

no not recommended.

changing the camber will dramatically change the toe. as you add more negative camber you will add toe-in, not what you want on the track.

 

That is exactly what I was worried about. I guess that I was hoping that the dynamics of the evo suspension would allow the addition if negative camber without it having a dramatic effect on the toe.

I guess what I could do is install some camber plates with street setting, mark the toe and camber settings and then do the same for track settings. I could then toggle between them the night before an event.

Is the toe adjustment easily accessible? Are there any solutions to make what I am looking to do easier?

Thanks for the info,

 

hmmm... see, I prefer fairly sharp turn-in and slight oversteer at exit.

before adding negative camber the car pushed pretty hard on turn-in and then caught at the very last minute (in mid to fairly sharp turns). Not fun IMO, and the tires looked like what you explained.

the same day, in the afternoon, I jacked up the car, added signifcant negative camber in front, did not touch the toe, ran the same cold tire pressures all day (35 cold) and the car felt alot better.. it went were I wanted it to and there was definitly less understeer (nearly none). Lots more fun. Didnt have a transponder but sure felt faster. Also, my front tire (hot) pressures went down compared to the morning sessions and on top of that it was a little warmer outside aswell.

what gives? I thought Toe out (not toe in) would generate that sort of result.....

I realize that preffered toe settings can vary greatly pending personal driving styles but based on what I said, wouldnt toe-in create the opposite effect of what I wanted? Did the severe negative camber compansate for it?

 

The places name is "Roger Kraus Tires" 510-582-5031 Give them a call, they are located at Castro Valley, CA (near bay area) They do alignments for many pro race cars! Give them a call!

 

I'd love to be able to add additional negative camber like that on the fly for track days. With the stock settings I experience exactly what you do. The outside of the tires get chewed up something severe and the insides are untouched. The heat rises in the outsides faster than the rest of the tires and eventually the ADvans get slippery.

 

I think the added camber balanced out the toe change. Resulting in better handeling overall, but still not as good as it could be. When I changed from stock camber to the max adjustment on the camber bolt, there was a good deal of change in the toe.

I've got some camber plates on order and when I get the car aligned I'm going to play around with the adjustment while the car is on the machine. I'm hopeing that I can come up with a compromise setting for toe that will allow me to go from -3.5 camber for track and maybe -2 or so for the street.

 

let us know once you got a good setting.

 

Scottybob,
I am very interested in what you find out on the alignment rack. I do not yet have camber plates installed and with Hotchkis springs the max negative camber that I can acheive and still retain near zero toe in up front is -1.6 on the left and -1.9 on the right. This setup leaves me with -.01 toe-in on both sides. As already mentioned, any more negative camber results in more toe-in. The question is when dialing out understeer which is more effective, increased negative camber or increased toe-in? I am sure that there is a point of diminishing returns using either method but what is more important to preserve?

 

I'm going to start putting these on this afternoon. Hopefully done and aligned by tomorrow evening...

 

HKS, Works, and I think Cusco make their own camber plates that come seperate from the coilovers. Tien I guess does too. Wired speedlab has the HKS and Tien here:

Would a quick adjustment of the stock system be worthwhile for camber gains only?
