Default Autocrossing/tracking..?

Hi guys,
I was just curious how many here that does any autocrossing and/or tracking?

I've started autocrossing and that is sure good fun, although you really notice that it is a heavy car and that you do need mods to be able to compete with other cars of the 'same' caliber.

Would be fun to see some other RS out there!

Default Quite a few of us track our RS4's here in the Northeast / New England

It's quite fun stock.

Semi-race pads and brake fluid are an absolute must. Once you do this, the brakes are fine.

Some will say that you "need" to switch to better brakes like the Alcons, because the stock rotors will wear quickly with track hours. But right now I have 30K miles on my rotors, with 2 track events. Even if I had to replace the rotors, I could purchase 4 sets of rotors for the cost of one Alcon brake kit. So the cost/benefit trade off for 4 track events per year is not justified for me.

Next modifications for track/street are the H-sport sway bars, and Bridgestone RE-01R tires, which go on in two days.

Default I've autocrossed it once...

and it was fun. The power and lack of turbo spool were very evident compared to the TT.

Default Re: Autocrossing/tracking..?

how many of you guys out there can heel toe shift with the US factory setup/location of the brake and accelerator?

Has anyone adjusted their accelerator pedal to make it easier to heel/toe shift.

Default I would say it's less about the car being heavy and more about some track time in the car

It can hang with if not beat cars in the "same" caliber, you just have to learn how to get the most out of it. The RS4 drives so much differently than any Audi I have owned and once you get some more track time you will learn how to use the car to avoid the weight. I dropped quite a bit of time off my laps once I stopped fighting the weight and learned to feel when to do things. You can break so much later than you think and get on the gas earlier than you think. Try different approaches on different runs. Remember, each lap is not necessarily about the best time you can get. Use a few of those laps to learn things and then incorporate your new found knowledge for a hot lap.

Default Tyre pressures make a HUGE difference...

Getting the tyre pressure right was the most important improvement for me... making the car more neutral... which droped times from 62.8 sec laps to 60.5 on my local short track. This puts it up with the 'small caliber + r-spec tyre' guys.

I'm still running standard P-Zero street tyres (RE-01R are illegal in Australia for street use) and I'm getting approx +7psi to +8psi increase between cold and hot.

Settings I have been using are;
IF Front Left = hardest worked tyre (i.e mainly RH corners)
THEN
Front Right = Front Left +0psi to +1psi
Rear Left = Front left +2psi to +3psi
Rear Right = Rear Left +0psi to +1psi
and set hardest working tyre (in this case the front left) to achieve about 40psi to 41psi (so about 34psi cold)

I do. It's not the most ideal pedal set-up for heel-toeing but workable.
