Does anyone have experience autocrossing the RDX? I'm thinking about running my stock RDX, just to get a better feel for how it performs.

I've autocrossed before and already know that I need to run higher tire pressures, but I've never done it with an AWD vehicle.

Can anyone suggest starting tire pressures?

 

err, you REALLY want to try AutoXing this boat? with an automatic transmission and 4,000lb curb weight, you're just asking for a frustrating day.

However, with this car, if I were to actually AutoX it (which I never would), I'd be running about 44lbs front and 40lbs rear to start, then adjust from there, depending on over/understeer tendancies.

 

Thanks. I don't plan on taking LTD. Just want to take it out to see what it's like driving closer to the limit.

But I amazed myself, and several spectators, many years ago, when I ran my 280Z in an autocross, and then was allowed to run my 4,000 lb Old Cutlass for a "fun run". My time was fast enough to have placed 4th in the class with the Z. Took a completely different line and style, but it worked.

Thanks again for the advice. The Tirerack had some starting tire pressures for FWD, front-engined RWD and rear engined RWD, but nothing for AWD.

I still haven't figured out or decide on whether to run with the traction control/VSA turned off or not. Let me know if you have any ideas.

 

Oh, I'd definitely turn it off. Shoot, I turn it off for regular daily driving! :lol:

I can feel the VSA holding me back when I just want to have "fun" on an off-ramp, so I think if you tried to get any sort of drifting/sliding action in an AutoX, it'll clamp down on those brakes right away.

I used to AutoX AWD exclusively (Subaru Impreza 2.5RS, back before the WRX was available in the US) and we usually were slightly higher pressures in front and softer in rear, but then adjusting accordingly. Those cars were less nose-heavy and didn't have SH-AWD, so we could get away with a slightly more even pressure front to rear. I think with the system on the RDX, it's not as likely to oversteer if the front tires are firmers than the rears.

 

Thanks for the advice. Like I said, I'm not going out with the goal of setting low time of day. Just out to have some really spirited driving that I can't do on the road.

 

I was wondering if someone had actually took their RDX to autox. Please have someone video tape the session(s), and post it here! It will be something to look forward to.

Good luck!

 

i'd do a transmission fluid drain and fill before going out and rev that puppy!, also do one drain and fill after the event.

 

Mau108,

Why the transmission fluid drain and refill before and after the autocross?

 

I'm all for autocrossing it!

All this baby needs is some custom sway bars!!! ;p

Let us know how you do!
