I am setting my MR up for autox in SM class. I haven't had this car out on the dry, just did 2 snowcrosses with it. Anyhow, I like a car to understeer and can't stand the oversteering push. From what I have read, adding a adjustable rear sway bar helps with this. I am also having the car aligned too with autox in mind. What air pressures do you guys run with the stock tires and similar set ups. BTW, I am in SM because of my fuel pump. I ran in SM with my Integra GSR for 3 years and like the people in my region in that class.

Thanks

 

what did you do to your fuel pump? Normally that would put you in ESP

 

You got your understeer and oversteer mixed up. Understeer pushes thru a turn. An adjustable rear sway bar will give you more oversteer.

 

Opps, you are right. I meant I like a car that oversteers, typed that *** backwards. I was told that changing the stock fuel pump out would put me in SM. With the other mods I could have been in either ESP or STU.

 

no fuel system is unrestricted, you should be able to run ESP.

Here is a link to the official rules

Wow, you are right when it comes to the fuel pump. I was misinformed. According to those rules though my reflashed ecu controls my boost, which would put me in SM. I had Dynoflash (al) reflash my ecu with EcuTek program. Is that correct? Anyone have a basic starting point for air pressure in tires based on someone who likes oversteering car. People who run the MR if they could give me some ideas on these tire pressures, Thanks again!

 

Don't know specifically about the MR, but in the stock Evo on Advans oversteer can be had in varying degrees just by having the rear tire pressures approach the fronts; try 42f/41r cold pressures and adjust from there; just don't brake too late going into turns. Trail braking a bit is OK, braking early and hard is OK, but moderate braking late in the corner leads to understeer every time.

P.S. Don't forget to let the air down after the Autocross and get the rears about 3 psi below the fronts before driving on the highway. Don't ask me how I know this is important.

 

I take my license plate off when I race (no reason ) and forgot to put it on one time. Luckily I stopped to eat. I sat down by the window and was staring at my car when I realized. Would have been fun getting pulled over for that. Thanks for the tire pressure info.
